BS: 5234 Testing

� The Building Test Centre offers a wide range of construction expertise covering the areas of fire, acoustics and structures.

� The Building Test Centre is one of the most well respected test centres in Europe with a range of facilities not matched anywhere else within the UK.

� The facility was purpose built in 1987 to test and evaluate the strength and robustness of lightweight building techniques.

UKAS

� The United Kingdom Accreditation Service (UKAS) is the body responsible for assessing and accrediting the competence of measurement, testing, inspection and certification of systems, products and personnel.

� The Building Test Centre is a UKAS accredited testing laboratory (No. 0296) for a wide range of BS, EN and ISO test methods; test reports issued by the Building Test Centre carry the same weight as those from all other accredited test houses.

BS: 5234 Testing


BS: 5234Partition Grade Testing

� The testing comprises a series of tests which examine the partition systems suitability for a given partition duty. Each test method is specific for the duty grade required and has strict acceptance criteria.


BS: 5234Partition Stiffness

� Partition Stiffness - A point load is applied to the partition and the maximum deflection together with any residual damage recorded.


BS:5234Hard Body Impacts

� Hard body impacts - two levels of impact are applied to the partition firstly to assess the resistance to damage of the partition lining and the second to assess the resistance to perforation.


BS: 5234Soft Body Impacts

� Soft Body Impacts - two level of impact are applied the first to assess the resistance to aesthetic damage and the second to assess the resistance to structural damage.


BS:5234Door Slamming

� Door slamming - a door built within the partition system is mechanically slammed and the deformation and damage on the partition system assessed.


BS: 5234Duty Grading


Grade Category of Duty Examples

Light Duty

Adjacent space only accessible to persons with high incentive to exercise

care. Small chance of accident occurring or of misuse.

Domestic

accommodation

Medium Duty

Adjacent space moderately used primarily by persons

with some incentive to exercise care. Some chance of

accident occurring and of misuse.

Office

Accommodation


Grade Category of Duty Examples

Heavy Duty

Adjacent space frequently used by the public and others

with little incentive to exercise care chances accident occurring and

misuse.

Public circulation areas

Industrial areas

Severe Duty

Adjacent space intensively used by the public and others

with little incentive to exercise a care. Prone to

vandalism and abnormally rough use.

Major circulation

areas

Heavy industrial

areas

BS: 5234Duty Grading

Optional Testing

� The standard also includes optional test methods, which are not included in the duty grading system these are:


Crowd Pressure

� Crowd Pressure - a line load is applied to the partition and the partitions ability to resist the load assessed.


Heavyweight Anchorages


� Heavyweight Anchorages –This test is to simulate heavyweight fixings such as wash basins, wall cupboards etc.

Lightweight Anchorages


� Lightweight Anchorages –The Pull Out – Pull Down Tests is to simulate light weight fixings such as Pictures, shelving etc.

Pressure Testing (UDL)

� The Building Test Centre is able to offer UKAS accredited positive or negative pressure testing on partitions up to a height of 6m.

� The rig applies a uniformly distributed load (UDL) over the surface of the partition allowing the bending stiffness characteristics of the partition system to be evaluated.


Racking Resistance

� Racking resistance is the stiffness contribution offered by internal walls buttressing against an external walls that are subject to wind loading. The test method was developed to be applied to timber framed buildings but can easily be adapted for steel framed construction techniques.
