BS52
18、34-2 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. BS5234-2 is new whereas BS5234-1:1992 is a complete revision of the1975 edition, which is withdrawn. The test methods t
19、o determine the effect of large soft body impacts and door slamming are similar to those in ISO7892 and ISO7894 respectively. However, it was found that the small hard body impact test method given in ISO7892 could be hazardous and required too much space to achieve the required energies, so a diffe

Users of this British Standard are advised to consider the desirability of assessment and registration of a suppliers quality systems against the appropriate Part of BS5750 by a third party certification body. A British Standard does not

Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside fro

23、Scope This Part of BS5234 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
24、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 th
25、e 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 1Tests may be used individually or in combination. A specimen right-angle junction is required to be teste
26、d 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
27、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 re
28、gardless 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
29、, etc. Masonry partitions should be designed for structural requirements in accordance with BS5628-1:1978, BS5628-2:1985 and BS5628-3:1985. 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 o
30、f BS5234. 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 of0.75kN/m this may be sufficient to satisfy the wind loading requirement. (See 8.4 of BS5234-1:1992.) 1.2 References 1.2
31、.1 Normative references This Part of BS5234 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 revisions
32、 of, any of these publications apply to this Part of BS5234 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 this s
33、tandard 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 BS5234, the definitions given in BS5234-1:1992 apply. 1.4 Grades For the purposes of this standard, partitions are graded according to the level of activ
34、ity in adjacent spaces and the degree of care likely to be exercised by people in the area (seeTable 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 particular grade,
35、 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 subclause
36、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 by the m
37、ethod 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.BS5234-2:1992 2 BSI 03-1999 The performance achieved shall be identified by criteria only without reference to grade, for example: “BS 5234-2 p
38、erformance compliance for stiffness: at the applied load of500N the maximum deflection was16mm and the maximum residual deformation was2mm”.

45、, etc.), other than superficial cracking of the surface. The maximum deflection and residual deformation shall not exceed the limits for the grade being tested given in Table 4. NOTEOnly superficial cracks which represent aesthetic damage are acceptable. Table 4 Stiffness: applied loads and deflecti
46、on limits 1.6.2 Surface damage by small hard body impact The partition and a right-angle junction shall be tested as described in Annex B and shall be subjected to the impact energy for the grade being tested as given in Table 5. Evidence, including photographs showing the nature and extent of surfa
47、ce damage and, if relevant, extent of damage, depth of indent, etc., shall be provided by the test authority to enable judgement to be made as to whether the damage is acceptable. NOTENo specific criterion for acceptance is given because the impact damage will vary with different materials and forms
48、 of construction; some surface damage may be acceptable because it can easily be repaired. Table 5 Small hard body impact test (surface damage) 1.6.3 Resistance to damage by impact from a large soft body When tested as described in Annex C the partition and a right-angle junction shall be capable of
49、 withstanding the impact energies for the grade being tested as given in Table 6 without sustaining either permanent deformation in excess of2mm or any damage. Any local damage that can be easily repaired to regain the partitions original properties shall be permitted.
