Apakah Vibrasi itu

Vibration is defined by its magnitude and frequency The magnitude of vibration could be expressed as the vibration displacement (in meters)

the vibration velocity (in meters per second) or the vibration acceleration (in meters per

second per second or mssup2) Most vibration transducers produce an output

that is related to acceleration so acceleration has traditionally been used to describe vibration

What is Hand-Arm Vibration

Hand-Arm Vibration is the transfer of vibration from a tool to a workerrsquos hand and arm

Acceleration - the rate of change of velocity in speed or direction per unit time (eg per second)

The amount of HAV is related to the acceleration level of the tool when grasped by the worker and in use The vibration is typically measured at the handle of the tool while in use to determine the acceleration levels transferred to the worker

Whole Body VibrationWhole Body Vibration

Whole Body VibrationWhole Body Vibration -WBV -WBV WBV is caused by machinery vibration passing through the buttocks of seated

people or the feet of standing people The most widely reported WBV injury is back pain

Many sources of back injury in addition to WBV which must be adequately controlled if risk of back pain and injury is to be minimised

Those at risk include regular drivers of Construction and quarrying vehicles and machinery Tractors and other agricultural and forestry machinery Industrial trucks such as lift trucks Road haulage vehicles rail vehicles and buses Those operating large static compaction hammering and mobile crushers can be

exposed to high levels of WBV Those working on vibrating platforms

Whole Body Vibration(WBV)

WBV refers to mechanical energy oscillations which are transferred to the body as a whole (in contrast to specific body regions) usually through a supporting system such as a seat or platform Typical exposures include driving automobiles and trucks and operating industrial vehicles

Vibrations arise when a body moves back and forth due to external and internal

forces Figure B1 In the case of whole-body vibration it may be the seat of a vehicle

or the platform on which a worker is standing that vibrates and this motion is

transmitted into the body of the driver

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

Frequency represents the number of times per second the vibrating body moves back

and forth It is expressed as a value in cycles per second more usually known as hertz

(abbreviated to Hz) For whole-body vibration the frequencies thought to be important range

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

y and another (the Wk weighting) applies to the vertical z-axis vibration

Both parameters A(8) and VDV are defined in ISO 2631-11997

The vibration directive allows for two vibration assessment methods

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

vibration dose value of 91 ms175)bull a daily exposure limit value of 115 mssup2(or at the choice of the EC Member State a

vibration dose value of 21 ms175)

Human exposure to whole-body vibration should be evaluated

using the method defined in International Standard

ISO 2631-11997 and detailed practical guidance on using the

method for measurement of vibration at the workplace is given in

EN 142532003

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

person or the feet of a standing person (see Annex B) it isexpressed in units of metres per second squared (mssup2)

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

It is the highest of three orthogonal axis values (14VDVwx 14VDVwy or VDVwz) that

is used for the exposure assessment

What is Hand-Arm Vibration

Hand-Arm Vibration is the transfer of vibration from a tool to a workerrsquos hand and arm

Acceleration - the rate of change of velocity in speed or direction per unit time (eg per second)

The amount of HAV is related to the acceleration level of the tool when grasped by the worker and in use The vibration is typically measured at the handle of the tool while in use to determine the acceleration levels transferred to the worker

Whole Body VibrationWhole Body Vibration -WBV -WBV WBV is caused by machinery vibration passing through the buttocks of seated

people or the feet of standing people The most widely reported WBV injury is back pain

Many sources of back injury in addition to WBV which must be adequately controlled if risk of back pain and injury is to be minimised

Those at risk include regular drivers of Construction and quarrying vehicles and machinery Tractors and other agricultural and forestry machinery Industrial trucks such as lift trucks Road haulage vehicles rail vehicles and buses Those operating large static compaction hammering and mobile crushers can be

exposed to high levels of WBV Those working on vibrating platforms

Whole Body Vibration(WBV)

WBV refers to mechanical energy oscillations which are transferred to the body as a whole (in contrast to specific body regions) usually through a supporting system such as a seat or platform Typical exposures include driving automobiles and trucks and operating industrial vehicles

Vibrations arise when a body moves back and forth due to external and internal

forces Figure B1 In the case of whole-body vibration it may be the seat of a vehicle

or the platform on which a worker is standing that vibrates and this motion is

transmitted into the body of the driver

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

Frequency represents the number of times per second the vibrating body moves back

and forth It is expressed as a value in cycles per second more usually known as hertz

(abbreviated to Hz) For whole-body vibration the frequencies thought to be important range

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

y and another (the Wk weighting) applies to the vertical z-axis vibration

Both parameters A(8) and VDV are defined in ISO 2631-11997

The vibration directive allows for two vibration assessment methods

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

Human exposure to whole-body vibration should be evaluated

using the method defined in International Standard

ISO 2631-11997 and detailed practical guidance on using the

method for measurement of vibration at the workplace is given in

EN 142532003

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

What is Hand-Arm Vibration

Hand-Arm Vibration is the transfer of vibration from a tool to a workerrsquos hand and arm

Acceleration - the rate of change of velocity in speed or direction per unit time (eg per second)

The amount of HAV is related to the acceleration level of the tool when grasped by the worker and in use The vibration is typically measured at the handle of the tool while in use to determine the acceleration levels transferred to the worker

Whole Body VibrationWhole Body Vibration

Whole Body VibrationWhole Body Vibration -WBV -WBV WBV is caused by machinery vibration passing through the buttocks of seated

people or the feet of standing people The most widely reported WBV injury is back pain

Many sources of back injury in addition to WBV which must be adequately controlled if risk of back pain and injury is to be minimised

Those at risk include regular drivers of Construction and quarrying vehicles and machinery Tractors and other agricultural and forestry machinery Industrial trucks such as lift trucks Road haulage vehicles rail vehicles and buses Those operating large static compaction hammering and mobile crushers can be

exposed to high levels of WBV Those working on vibrating platforms

Whole Body Vibration(WBV)

WBV refers to mechanical energy oscillations which are transferred to the body as a whole (in contrast to specific body regions) usually through a supporting system such as a seat or platform Typical exposures include driving automobiles and trucks and operating industrial vehicles

Vibrations arise when a body moves back and forth due to external and internal

forces Figure B1 In the case of whole-body vibration it may be the seat of a vehicle

or the platform on which a worker is standing that vibrates and this motion is

transmitted into the body of the driver

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

Frequency represents the number of times per second the vibrating body moves back

and forth It is expressed as a value in cycles per second more usually known as hertz

(abbreviated to Hz) For whole-body vibration the frequencies thought to be important range

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

y and another (the Wk weighting) applies to the vertical z-axis vibration

Both parameters A(8) and VDV are defined in ISO 2631-11997

The vibration directive allows for two vibration assessment methods

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

a daily exposure action value of 05 mssup2(or at the choice of the EC Member State a

vibration dose value of 91 ms175)bull a daily exposure limit value of 115 mssup2(or at the choice of the EC Member State a

vibration dose value of 21 ms175)

Human exposure to whole-body vibration should be evaluated

using the method defined in International Standard

ISO 2631-11997 and detailed practical guidance on using the

method for measurement of vibration at the workplace is given in

EN 142532003

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

person or the feet of a standing person (see Annex B) it isexpressed in units of metres per second squared (mssup2)

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

It is the highest of three orthogonal axis values (14VDVwx 14VDVwy or VDVwz) that

is used for the exposure assessment

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

Frequency represents the number of times per second the vibrating body moves back

and forth It is expressed as a value in cycles per second more usually known as hertz

(abbreviated to Hz) For whole-body vibration the frequencies thought to be important range

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

y and another (the Wk weighting) applies to the vertical z-axis vibration

Both parameters A(8) and VDV are defined in ISO 2631-11997

The vibration directive allows for two vibration assessment methods

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

Human exposure to whole-body vibration should be evaluated

using the method defined in International Standard

ISO 2631-11997 and detailed practical guidance on using the

method for measurement of vibration at the workplace is given in

EN 142532003

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

person or the feet of a standing person (see Annex B) it isexpressed in units of metres per second squared (mssup2)

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

It is the highest of three orthogonal axis values (14VDVwx 14VDVwy or VDVwz) that

What is Hand-Arm Vibration

Hand-Arm Vibration is the transfer of vibration from a tool to a workerrsquos hand and arm

Acceleration - the rate of change of velocity in speed or direction per unit time (eg per second)

The amount of HAV is related to the acceleration level of the tool when grasped by the worker and in use The vibration is typically measured at the handle of the tool while in use to determine the acceleration levels transferred to the worker

Many sources of back injury in addition to WBV which must be adequately controlled if risk of back pain and injury is to be minimised

Those at risk include regular drivers of Construction and quarrying vehicles and machinery Tractors and other agricultural and forestry machinery Industrial trucks such as lift trucks Road haulage vehicles rail vehicles and buses Those operating large static compaction hammering and mobile crushers can be

exposed to high levels of WBV Those working on vibrating platforms

Vibrations arise when a body moves back and forth due to external and internal

forces Figure B1 In the case of whole-body vibration it may be the seat of a vehicle

or the platform on which a worker is standing that vibrates and this motion is

transmitted into the body of the driver

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

Frequency represents the number of times per second the vibrating body moves back

and forth It is expressed as a value in cycles per second more usually known as hertz

(abbreviated to Hz) For whole-body vibration the frequencies thought to be important range

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

y and another (the Wk weighting) applies to the vertical z-axis vibration

Both parameters A(8) and VDV are defined in ISO 2631-11997

The vibration directive allows for two vibration assessment methods

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

vibration dose value of 91 ms175)bull a daily exposure limit value of 115 mssup2(or at the choice of the EC Member State a

vibration dose value of 21 ms175)

Human exposure to whole-body vibration should be evaluated

using the method defined in International Standard

ISO 2631-11997 and detailed practical guidance on using the

method for measurement of vibration at the workplace is given in

EN 142532003

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

person or the feet of a standing person (see Annex B) it isexpressed in units of metres per second squared (mssup2)

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

It is the highest of three orthogonal axis values (14VDVwx 14VDVwy or VDVwz) that

is used for the exposure assessment

Vibrations arise when a body moves back and forth due to external and internal

forces Figure B1 In the case of whole-body vibration it may be the seat of a vehicle

or the platform on which a worker is standing that vibrates and this motion is

transmitted into the body of the driver

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

Frequency represents the number of times per second the vibrating body moves back

and forth It is expressed as a value in cycles per second more usually known as hertz

(abbreviated to Hz) For whole-body vibration the frequencies thought to be important range

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

y and another (the Wk weighting) applies to the vertical z-axis vibration

Both parameters A(8) and VDV are defined in ISO 2631-11997

The vibration directive allows for two vibration assessment methods

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

Human exposure to whole-body vibration should be evaluated

using the method defined in International Standard

ISO 2631-11997 and detailed practical guidance on using the

method for measurement of vibration at the workplace is given in

EN 142532003

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

person or the feet of a standing person (see Annex B) it isexpressed in units of metres per second squared (mssup2)

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

It is the highest of three orthogonal axis values (14VDVwx 14VDVwy or VDVwz) that

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

Vibrations arise when a body moves back and forth due to external and internal

forces Figure B1 In the case of whole-body vibration it may be the seat of a vehicle

or the platform on which a worker is standing that vibrates and this motion is

transmitted into the body of the driver

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

forces Figure B1 In the case of whole-body vibration it may be the seat of a vehicle

or the platform on which a worker is standing that vibrates and this motion is

transmitted into the body of the driver

Vibration is defined by its magnitude and frequency The magnitude of vibration

could be expressed as the vibration displacement (in metres) the vibration velocity (in

metres per second) or the vibration acceleration (in metres per second per second or

mssup2) However most vibration transducers produce an output that is related to

acceleration (their output is dependent on the force acting on a fixed mass within the

transducer and for a fixed mass force and acceleration are directly related) so

acceleration has traditionally been used to describe vibration

Frequency represents the number of times per second the vibrating body moves back

and forth It is expressed as a value in cycles per second more usually known as hertz

(abbreviated to Hz) For whole-body vibration the frequencies thought to be important range

from 05Hz to 80Hz However because the risk of damage is not equal at all

frequencies a frequency-weighting is used to represent the likelihood of damage from

the different frequencies As a result the weighted acceleration decreases when the

frequency increases For whole-body vibration two different frequency weightings

are used One weighting (the Wd weighting) applies to the two lateral axes x and

y and another (the Wk weighting) applies to the vertical z-axis vibration

Both parameters A(8) and VDV are defined in ISO 2631-11997

The vibration directive allows for two vibration assessment methods

bull the daily exposure A(8) - the continuous equivalent acceleration normalised to

an 8 hour day the A(8) value is based on root-mean-square averaging of the

acceleration signal and has units of mssup2 andbull the vibration dose value (VDV) is a cumulative

dose based on the 4th root-meanquadof the acceleration signal with units of ms175

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

person or the feet of a standing person (see Annex B) it isexpressed in units of metres per second squared (mssup2)

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

It is the highest of three orthogonal axis values (14VDVwx 14VDVwy or VDVwz) that

is used for the exposure assessment

vibration dose value of 91 ms175)bull a daily exposure limit value of 115 mssup2(or at the choice of the EC Member State a

vibration dose value of 21 ms175)

Human exposure to whole-body vibration should be evaluated

using the method defined in International Standard

ISO 2631-11997 and detailed practical guidance on using the

method for measurement of vibration at the workplace is given in

EN 142532003

The root-mean-square (rms) vibration magnitude is expressed in

terms of the frequency-weighted acceleration at the seat of a seated

person or the feet of a standing person (see Annex B) it isexpressed in units of metres per second squared (mssup2)

The rmsvibration magnitude represents the average acceleration

over ameasurement period It is the highest of three orthogonal

axesvalues (14awx 14awy or awz) that is used for the

exposureassessment

The vibration dose value (or VDV) provides an alternative measure of vibration

exposure The VDV was developed as a measure that gives a better indication of the

risks from vibrations that include shocks The units for VDV are metres per second to

the power 175 (ms175) and unlike the rms vibration magnitude the measured VDV

is cumulative value ie it increases with measurement time It is therefore important

for any measurement of VDV to know the period over which the value was measured

It is the highest of three orthogonal axis values (14VDVwx 14VDVwy or VDVwz) that

is used for the exposure assessment
