12、, na, Mon Dec 04 16:37:09 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5459-3:1983 ii BSI 07-1999 Foreword This Part of this British Standard has been prepared under the direction of the Furniture and Household Equipment Standards Committee in recognition of the need for performance standards for o
13、ffice furniture; it is intended to provide assurance that office furniture made in compliance with it is sound and reasonably durable, factors that are difficult to assess by inspection at the time of purchase. The requirements are based on performance tests that are intended to ensure a satisfactor
14、y article whatever materials or manufacturing methods are used. The tests have been devised to take into account the conditions and hazards to which office furniture is subjected during everyday use, and in using them the Technical Committee wishes to acknowledge the considerable assistance given to
15、 it by the Furniture Industry Research Association (FIRA), Whose research work has been utilized whenever possible. At the request of the Business Equipment Trade Association, FIRA has completed a special programme of testing during which several typical items of office furniture were subjected to t
16、he strength and stability tests and due account of this work has been taken in the performance figures given in this standard. Subsequent to the completion of the testing programme, the opportunity was taken to align the test methods with those in international work in progress within ISO/TC 136/SC
17、1 “Furniture test methods”. An additional loading test for flaps, and a test for displacement of the bottom surface of drawers was also included using the tests proposed in ISO Draft Proposal DP 7170 “Furniture storage units determination of strength and durability”. The performance tests specified
18、in this standard are similar to those given in BS 4875-3 for domestic and contract furniture and do not assess ageing and wear. The tests are designed to be applied to an article of furniture that is fully assembled and ready for use. At present, no requirements are specified in this standard for su
19、rface finishes. It is intended to introduce requirements for surface finishes at a later date in an amendment to this standard. This standard forms Part 3 of a specification for office furniture of which the other Parts are Part 1 “Desks and tables” and Part 2 “Adjustable chairs”. Attention is drawn
20、 to BS 4438 which specifies dimensional and performance requirements for filing cabinets and suspended filing pockets. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with
21、a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 10, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amen
22、dments incorporated. This will be indicated in the amendment table on the inside front cover.

23、cribes applicable tests for office storage furniture. The test methods give three levels of severity of testing, i.e. furniture intended for general use (test level G), heavy use (test level H) and severe use (test level S). The requirements do not apply to office desks, mechanical filing and retrie
24、val systems, rotary filing systems, drawing office storage furniture and furniture for archival storage. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definition For the purposes of this Part of BS 5459 the following definition applies. 2.1 of
25、fice storage shelves and open or closed cupboards and cabinets NOTEThis definition includes free-standing, fixable and mobile items, e.g. shelf systems. 3 Description of performance tests 3.1 Functional tests 3.1.1 Principle. The functional tests simulate the loads imposed on an article of furniture
26、 during the performance of its primary function. The following tests (3.1.2 to 3.1.4) fall within the functional test category. 3.1.2 Sustained load test. The sustained load test simulates the levels of continuous application that occur most frequently. 3.1.3 Operational test. The operational test s
27、imulates the repetition of operations occurring during daily use. 3.1.4 Fatigue loading test. The fatigue loading test simulates that level of repeated loading that is likely to occur most frequently. 3.2 Non-functional tests 3.2.1 Principle. The non-functional tests simulate the loads imposed on an
28、 article of furniture as a result of the use to which it may reasonably be put outside the performance of its primary function. As such the test levels set in the non-functional tests represent the dividing line between reasonable misuse and abuse. The following tests (3.2.2 to 3.2.5) fall within th
29、e non-functional test category. 3.2.2 Static load test. The static load test consists in the steady and gradual application, up to the maximum that the article may be required to withstand occasionally, of a test load repeated a sufficient number of times to check the static strength of the article.
30、 3.2.3 Impact test. The impact test simulates impact or repetition of sudden operations that occur only occasionally. 3.2.4 Slam open and slam shut tests. The slam open and slam shut tests simulate sudden operations that occur only occasionally. 3.2.5 Carcase rigidity test. The carcase rigidity test
31、 simulates the forces employed when moving a loaded carcase. 4 Performance requirements 4.1 When tested in accordance with clauses 5 and 6, the article shall meet the requirements of 4.2 and 4.3 and, where appropriate, the requirements of 4.4 and 4.5 at the same test level in all tests. 4.2 There sh
32、all be no overbalancing during the tests. 4.3 The article shall not develop any of the following as a consequence of the tests: a) any fracture of any member, component or joint; b) any deformation or wear of any part or component that will essentially affect its function; c) any loosening of any me
33、ans of fixing components to the article; d) any loosening, shown to be permanent by hand racking the article, of any joint intended to be rigid. 4.4 The maximum deflection of each shelf or clothes hanging rail when tested in accordance with 6.1.1 shall not exceed the span divided by 100 for metals a
34、nd the span divided by 200 for all other materials. NOTEThe requirements for metals are different from those for other materials owing to their different time dependent properties. 4.5 When tested in accordance with 6.5.1 to 6.5.4, the force required to move the loaded drawer from rest shall not exc
35、eed 70 N and the force required to maintain constant movement shall not exceed 40 N. The drawer shall operate smoothly. NOTEGuidance on the scale of sampling is given in BS 6001.

36、 2 BSI 07-1999 5 General requirements for tests 5.1 Sequence of tests. The article of furniture shall be submitted in turn to each of the appropriate tests given in clause 6. The tests on each component, e.g. doors, shall be carried out in the specified sequence, but it is not necessary to test the
37、components of the article in any set sequence. Unless otherwise specified in the particular test method, during each test free-standing articles shall be supported on a true and level base; articles for wall attachment shall be mounted on a flat vertical surface in the manner intended by the manufac
38、turer. NOTE 1Test loads should be applied at a realistic rate and care should be taken to avoid kinetic heating since the functions represented do not occur continuously in practice. It is recommended that in the tests the rate of operation or loading of components does not exceed 15 cycles per minu
39、te including a 2 s delay in each cycle. NOTE 2For practical purposes, a force of 10 N may be taken to be equal to the downward force due to a mass of 1 kg. 5.2 Test loads. Unless otherwise specified in the particular test method, the test loads shall be as given in Table 1. Table 1 Test loads (1)a 5
40、.3 Moisture content. Before any article containing structural members made of timber or of other materials whose properties depend on moisture content is subjected to the strength tests, it shall be checked with an electric moisture meter to ensure that the moisture content is not higher than 12 %.
41、If the moisture content is too high, the article shall be allowed to dry out gently in a warm, ventilated room until the moisture content is below 12 %. The moisture content during testing shall be recorded if outside the range 8 % to 12 %. NOTEThe moisture content during testing should be reasonabl
42、y constant but it is recognized that there are many different conditions of end use which alter the moisture content. The low relative humidity possible in centrally heated premises can reduce moisture content to considerably less than 12 %, whilst other conditions can allow it to rise above 12 %. 5
43、.4 Examination before testing. Immediately before testing, the article shall be thoroughly inspected. Any defects in the members, joints or attachment of such components as flaps and extensions shall be noted so that these are not attributed to the effect of the tests when the tests have been comple
44、ted. 5.5 Tests on doors, flaps and drawers. For an article fitted with a number of flaps, drawers or doors that are identical in every respect (apart from their direction of opening and closing), it is necessary to test only one of the relevant flaps, drawers or doors. Other flaps, drawers or doors
45、fitted to the article shall each be tested separately. 6 Test methods NOTEFor information on the availability of test apparatus for carrying out the various test procedures apply to Central Enquiries Section, BSI, 2 Park Street, London W1A 2BS, enclosing a stamped addressed envelope for reply. 6.1 T
46、ests on shelves, horizontal surfaces and clothes hanging rails 6.1.1 Sustained load test. Load each component of the article given in Table 2 uniformly and simultaneously with the appropriate load given in Table 2 (see Figure 1). Maintain the load for 7 days. Record the maximum deflection. Component

49、apart, except for the distance between the lowest shelf and the bottom surface or the floor which shall be between 100 mm and 300 mm. Table 2 Test loads (2)a For wall or screen hung articles, i.e. articles not directly supported by the floor, the following additional test shall be carried out. Load the horizontal surfaces of the article with four times the load given in Table 1 for the appropriate test level. Maintain the load for 7 days. 6.1.2 Impact test. Carry out the following test in turn on each shelf and hor
