FOREWORD

This Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, after the draft finalized bythe Automotive Basic Standards Sectional Committee had been approved by the Transport Engineering DivisionCouncil.

This standard was first published in 1980. In this revision standard terms and definitions related to dimensions ofroad vehicles have been updated based on present usage. Definitions pertaining to weights have not been includedsince. 1S9211 :2003 ‘Terms and definitions of weights of road vehicles other than 2 and 3 wheelers’, already exitson the subject.

In order to achieve harmony with the international practices, this standard is based on 1S0612 : 1978(E) ‘Roadvehicles — Dimensions of motor vehicles and towed vehicles — Terms and definitions’, issued by the InternationalOrganization for Standardization.

The composition of the Committee responsible for formulation of this standard is given in Annex A.

1 SCOPE

This standard defines the terms relating to dimensionsof road vehicles.

1.1 Itdoes not deal with methods of measurement, theunits used in reporting the results, or the accuracyrequired or the order of magnitude of the dimensionsdefined.

1.2 Provisions of this standard apply to four wheelermotor vehicles as defined in IS 14272 (Part 1).

1.3 This standard does not cover road vehicles, suchas, motor cycles, mopeds or other vehicles, such as,agricultural tractors, which are only incidentally usedfor the carriage of persons or goods by road or fortowing on the road vehicles used for the carriage ofpersons of goods.

2-REFERENCES

2.”1The following standards contain provisions whichthrough reference in this text, constitute provisions ofthis standard. At the time of publication, the editionsindicated were valid.

Terms and definitions of weights ofroad vehicles other than 2 and 3wheelers (second revision)

Automotive vehicles — Types —Terminology: Part 1 Three and fourwheelers

3. I Unless otherwise stated with regard to one or moreof the items mentioned below, it should be understoodthat:

a) The supporting surface is horizontal; lengths andwidths are measured on the horizontal plane andheights in the vertical plane;

b)

c)

d)

e)

f)

The total weight of the vehicle is the maximumauthorised gross vehicle weight (GVW), theload being distributed according to themanufacturer’s instructions as per IS 92”11;

The tyres are inflated to the pressurecorresponding to the maximum authorized grossvehicle weight (GVW) of the vehicle;

The vehicle is stationary, its doors and windowsare closed and its wheels and articulated elementsare in positions corresponding tomovements ina straight line;

All wheels of the vehicle are resting on theground; and

The expression ‘mid-plane & the wheel’ thatoccurs in a number of definitions, designates theplane equidistant from the inner edges of the rim.

4 DEFINITION OF THE LONGITUDINALMEDIAN PLANE (OF THE VEHICLE) (seeFig. 1)

The vertical plane Y passing through the mid-points ofAB for front and rear axles, perpendicular to AB. A andB being defined as follows:

a)

b)

for each wheel, the vertical plane passing throughits axis cuts the mid-plane of the wheel [see3 (f)] following a straight line A which meetsthe supporting surface of the vehicle at one point;and

A and B are two points thus defined whichcorrespond to two wheels, both of which areeither steering or powered wheels, situatedrespectively at two ends of the same rear orimaginary axle.

NOTES

1 The Longitudinal.medianplane (of the vehicle) is also called‘the longitudinal plane of symmetry’ or Zero Y plane (see[S0 4130-1978 ‘Three dimensional reference system andfiducial marks — Definitions’).

2 In the case of dual wheels, the mid-plane of the dual wheelsis equidistant from the inner edge of one wheel and the outeredge of the other. The straight line A is, in this particular case,the intersection of the mid-plane of the dual wheels and thevertical plane passing through the axis of the axle pin.
