8、1996 Foreword This British Standard has been prepared by Technical Committee MHE/8 and is a revision of BS 4680 : 1971 Specification for clothes lockers, which is superseded and withdrawn. The range of widths and depths of locker sizes has been increased to agree with the wider range of lockers now

9、manufactured. The testing requirements have been expanded to ensure that lockers made in compliance with this standard will be sound and durable. Lockers are manufactured in other materials and to other dimensions, for example to fit a particular installation. Such lockers do not conform to this sta

10、ndard and should be the subject of agreement between the manufacturer and purchaser. Compliance with a British Standard does not of itself confer immunity from legal obligations. BSI 1996 1 BS 4680 : 1996 Specification 1 Scope This British Standard specifies requirements for the overall dimensions,

11、materials, fitments, finishes and type performance testing of three types of clothes locker used for industrial and commercial purposes. It does not apply to lockers designed for special applications. Lockers which conform to this standard will give satisfactory service in their intended environment

12、. However, failure may result as a consequence of service abuse, habitual misuse or an excessively long period of service. 2 Informative references This British Standard refers to other publications that provide information or guidance. Editions of these publications current at the time of issue of

13、this standard are listed on the inside back cover, but reference should be made to the latest editions. 3 Definitions For the purposes of this British Standard the following definitions apply. 3.1 locker A storage compartment with its own fastenable door. 3.2 unit One or more lockers, arranged verti

14、cally, contained within the overall dimensions specified in clause 5. 3.3 initial unit A unit with two sides. 3.4 extension unit A unit with one side; the open side is fixed to the initial unit or to the previous unit in the nest. 3.5 nest A series of initial or initial and extension units fixed sid

15、e by side. 3.6 general duty locker A locker which is designated as suitable for use in well supervised environments such as schools, colleges, hospitals and light industrial environments. 3.7 heavy duty locker A locker which is designated as suitable for use in poorly supervised or industrial enviro

16、nments. 4 Information and requirements to be agreed and to be documented 4.1 General The following items to be agreed between the contracting parties, which are specified in the clauses referred to, shall be fully documented.

NOTE. An example of an enquiry or order is given in annex A. 4.3 Options There are a number of opt

21、ions incorporated in this British Standard. In the event that the purchaser does not wish to implement any of these options at the time of enquiry and/or order, the manufacturer shall supply the product on the following basis: a) without base (see clause 7); b) without a seat (see clause 8); c) with

22、out hooks (see clause 12); d) without hanger rails (see clause 12); e) with a flat and level top (see clause 13); f) without door baskets (see clause 12).2 BSI 1996 BS 4680 : 1996 Depth Depth Depth Depth Width Width Width Width Type 1a - One locker fitted with shelf Type 2 - Two tier unit.

A.2 Order The order should be made out as follows: 1) 68 lockers general duty; 2) type 2 (two-tier); 3) reference size (400 mm3 400 mm); 4) 4 nests of 4 units 5 nests of 3 units 3 separate units; 5) stove enamelled; 6) colour; 7) locking by unmastered dea

All the lockers in this order are the same (type 2). However, if the requirement is for a number of lockers of various types, a sep

42、arate schedule should be prepared for each type of unit. Annex B (normative) Testing B.1 Principle B.1.1 General Test results shall be valid only for the type (model) of locker tested. The test specimen shall be representative of the production model in order to provide approval for the type (model)

43、 of locker tested. The sequence of testing shall be B.1.2, B.1.3, B.1.4. B.1.2 Static tests The static strength of the component parts is assessed. This determines the ability of the locker to withstand the high levels of loading that occur only occasionally. B.1.3 Wear tests The strength and durabi

44、lity of the component parts of the article are assessed. This determines the ability of the locker to withstand repeated operations, movement or application of loads encountered during daily use.6 BSI 1996 BS 4680 : 1996 Table B.2 Test loads applied to the part being tested Test level Top surface st

This determines the ability of the locker to withsta

Specification and test procedures for such special criteria should be agreed between supplier and customer prior to order (s

48、ee clause 4). NOTE 2. The loads and test loads are given in tables B.1, B.2 and B.3. B.2 General requirements for testing B.2.1 Test loading All loads and forces shall be measured to an accuracy of 5% . NOTE 1. The tests may be carried out by means of loads or forces. For practical purposes, a force

49、 of 10 N may be taken to be equal to the downward force due to a mass of 1 kg. For each component part, the tests shall be carried out in the order in which they appear in the appropriate sub-clause. NOTE 2. The compound parts of an item can be tested in any order and do not necessarily have to be carried out in the order given in B.1. B.2.2 Loading system The loads specified in table B.1 shall be applied to all accessories when not being tested. NOTE. The loads specified in table B.1 represent
