For a sample partition with a door when tested by the methods given in the annexes. Grades derived when tested for stiffness, hard and soft body impacts and door slamming. Performance levels and test methods are also given for crowd pressure, lightweight and heavyweight anchorages.

This Part of BS 5234 specifies the performance requirements for strength and robustness of a sample partition when tested by the methods given in the annexes.

The partition specimen to be tested is defined and includes a doorset and the surface finish of the partition where this is supplied as part of the partition.

Partition grade can be derived when all the relevant tests are applied to the test specimen and, where specified, to the specimen right-angle partition junction.

Performance levels are given for each requirement tested based on the frequency and/or intensity of the loads on the partition.

Methods of test are given for stiffness, hard and soft body impacts, door slamming, crowd pressure and for anchorages for lightweight fittings, wash basins and wall cupboards.

NOTE 1 Tests may be used individually or in combination.

A specimen right-angle junction is required to be tested for surface damage and perforation by a small hard body and for its resistance to damage by impact from a large soft body. Other junctions may be tested by the methods given in this standard but such tests are beyond its scope.

Lightweight and heavyweight anchorage tests specify brackets that are to be used to evaluate the performance level of the partition. Proprietary brackets may not be substituted to demonstrate conformance to this standard. Alternative test brackets may be used but such tests are beyond the scope of this standard.

The requirements tested may be applied to a partition regardless of the materials used in its construction. However, it would be unnecessary and/or inappropriate to apply some tests to some forms of construction; for example, heavyweight anchorage tests on movable partitions, screens or WC cubicles, hard body impact test on the glass of glazed partitions, etc. Masonry partitions should be designed for structural requirements in accordance with BS 5628-1:1978, BS 5628-2:1985 and BS 5628-3:1985. However, the design of some masonry partitions may need modification to achieve some of the performance criteria when tested by the methods given in this Part of BS 5234.

This standard does not include requirements for wind loading.

NOTE 2 If the partition specimen, when tested for crowd pressure as given in Annex G, meets the requirement of 0.75 kN/m this may be sufficient to satisfy the wind loading requirement. (See 8.4 of BS 5234-1:1992.)
