This Singapore Standard specifies the performance requirements for strength and robustness of a sample partition wall when tested by the methods given in the annexes.\n?\nThe partition wall 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 wall.\nPartition wall grade can be derived when all the relevant tests are applied to the test specimen and, where specified, to the specimen right-angle partition wall junction.\nPerformance levels are given for each requirement tested based on the frequency and/or intensity of the loads on the partition wall. .\nMethods 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.\nNOTE 1 - Tests may be used individually or in combination.\nA 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.\nLightweight and heavyweight anchorage tests specify brackets that are to be used to evaluate the performance level of the partition wall. 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.\nThe requirements tested may be applied to a partition wall 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, screens or WC cubicles, hard body impact test on the glass of glazed partition walls, etc. Masonry partition walls should be designed for structural requirements in accordance with BS 5628 : Part 1 : 1978, Part 2 : 1985 and Part 3 : 1985. However, the design of some masonry partition walls may need modification to achieve some of the performance criteria when tested by the methods given in this standard.\nThis standard does not include requirements for wind loading.\nNOTE 2 - If the partition wall 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 Clause 2.4.4 of SSCP90:2001).\n
