19、ion of the General Building Codes Technical Committee (B/209). BS 5234-2 specifies performance requirements for the strength and robustness of partitions, regardless of the materials and form of their construction, when tested by the methods given. BS 5234-2 is new whereas BS 5234-1:1992 is a comple
20、te revision of the 1975 edition, which is withdrawn. The test methods to determine the effect of large soft body impacts and door slamming are similar to those in ISO 7892 and ISO 7894 respectively. However, it was found that the small hard body impact test method given in ISO 7892 could be hazardou
21、s and required too much space to achieve the required energies, so a different apparatus is used in this standard. Assessed capability. Users of this British Standard are advised to consider the desirability of assessment and registration of a suppliers quality systems against the appropriate Part o

Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligat

This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the

General 1.1 Scope
25、 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
26、 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 pa
27、rtition. 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 1Tests may be used individually or in combination. A specimen right-angle junction is required to be tested fo
28、r 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 b
29、e 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 regard
30、less 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, et
31、c. 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
32、 BS 5234. This standard does not include requirements for wind loading. NOTE 2If 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.) 1.2 References
33、1.2.1 Normative references This Part of BS 5234 incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text and the publications are listed on the inside back cover. Subsequent amendments to, or revis
34、ions of, any of these publications apply to this Part of BS 5234 only when incorporated in it by updating or revision. 1.2.2 Informative references This Part of BS 5234 refers to other publications that provide information or guidance. Editions of these publications current at the time of issue of t
35、his standard are listed on the inside back cover, but reference should be made to the latest editions. 1.3 Definitions For the purposes of this Part of BS 5234, the definitions given in BS 5234-1:1992 apply. 1.4 Grades For the purposes of this standard, partitions are graded according to the level o
36、f activity in adjacent spaces and the degree of care likely to be exercised by people in the area (see Table 1); for a partition to be described as having a particular grade it shall pass all the tests for that grade. 1.5 Performance requirements 1.5.1 Grade For a partition to conform to a particula
37、r grade, a specimen partition shall be tested by the methods given in Annex A to Annex F and a specimen partition corner junction shall be tested by the methods given in Annex B, Annex C and Annex D and shall satisfy the corresponding level of performance for that grade given in the corresponding su
38、bclause in 1.6. NOTEA summary of the requirements and principal test performance levels for each grade is given in Table 2. 1.5.2 Performance For a partition to conform to an individual performance requirement, a specimen partition and, if specified, a right-angle partition junction shall be tested
39、by the method given in the relevant annex and shall satisfy criteria for test performance that falls within the criteria given in the corresponding subclause in 1.6.

40、9 The performance achieved shall be identified by criteria only without reference to grade, for example: “BS 5234-2 performance compliance for stiffness: at the applied load of 500 N the maximum deflection was 16 mm and the maximum residual deformation was 2 mm”.
