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: 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.
Tel. 0115 945 1564 Fax. 0115 945 1562email: [email protected]
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.
Tel. 0115 945 1564 Fax. 0115 945 1562email: [email protected]
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
Tel. 0115 945 1564 Fax. 0115 945 1562email: [email protected]
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
Tel. 0115 945 1564 Fax. 0115 945 1562email: [email protected]
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
Tel. 0115 945 1564 Fax. 0115 945 1562email: [email protected]
� Heavyweight Anchorages –This test is to simulate heavyweight fixings such as wash basins, wall cupboards etc.
Lightweight Anchorages
Tel. 0115 945 1564 Fax. 0115 945 1562email: [email protected]
� 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.
Tel. 0115 945 1564 Fax. 0115 945 1562email: [email protected]
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.
