11、eakfast bars to withstand the maximum loadings specified for general domestic use with higher test levels specified for heavy domestic use. It is recognized that accidental overloads occur from time to time but it would be impracticable to specify requirements for assemblies to withstand such accide

Safety requirements are omitted from this Part of BS 6222 as they will be specified in EN 1153 Kitchen furniture Safety requirements and test methods for built-in a
13、nd free standing kitchen cabinets and work tops, which is in preparation. Other Parts of BS 6222 are as follows: Part 1: Specification for coordinating dimensions; Part 2: Specification for strength requirements and methods of test for fitted kitchen units; Part 3: Specification for performance requ
14、irements for durability of surface finish and adhesion of surfacing and edging materials; Part 4: Code of practice for protection, storage and installation of fitted kitchen units. NOTEAttention is drawn to BS 7376 and BS 7749. Product certification. Users of this British Standard are advised to con
15、sider the desirability of third party certification of product conformity with this British Standard based on testing and continuing product surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate Part of BS EN ISO 9000. Enquiries as to the availabil
16、ity of third party certification schemes are forwarded by BSI to the Association of British Certification Bodies. If a third party certification scheme does not already exist, users should consider approaching an appropriate body from the list of Association memebers. A British Standard does not pur
17、port to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. 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 front

20、nt damage. Many of the tests specified in this Part of BS 6222 are identical to those specified in BS 6222-2. It is emphasized that the purpose of this Part of BS 6222 is to specify strength requirements for complete peninsular, island and breakfast bar assemblies. BS 6222-2, whilst containing the s
21、ame tests, is applicable to individual units or components. Two grades are specified. The tests are for the repeated operation of doors, for the loading of storage surfaces and for the exceptional loads that should occur only occasionally. Tests carried out in accordance with this standard are inten
22、ded to demonstrate the ability of the item to give satisfactory service in its intended environment. It should be understood that such tests do not ensure that structural failure will not eventually occur as a result of habitual misuse or after an excessively long period of service. 1 Scope This Par
23、t of BS 6222 specifies strength requirements and methods of test for assembled peninsular units, island units and breakfast bars but does not specify safety requirements. This Part of BS 6222 does not specify requirements for individual units which are covered by BS 6222-2. The requirements are appl
24、icable to all materials and all types of construction. The tests do not take account of the effects of ageing or chemical degradation. 2 References 2.1 Normative reference This British Standard incorporates, by dated or undated reference, provisions from another publication. This normative reference
25、 is made at the appropriate place in the text and the cited publication is listed on the inside back cover. For dated references, only the edition cited applies; any subsequent amendments to, or revisions of the cited publication apply to this British Standard only when incorporated in the reference
26、 by amendment or revision. For undated references, the latest edition of the cited publication applies, together with any amendments. 2.2 Informative references This British Standard refers to other publications that provide information or guidance. Editions of these publications current at the time
27、 of issue of 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 breakfast bar a horizontal surface that is attached to one or more base units and that is
28、at a height convenient for use by a seated person 3.2 island unit an assembly of units attached to the structure of the building only at the floor 3.3 peninsular unit an assembly of units in which not more than one base unit and one overhead unit are attached to the structure of the building 3.4 she

Grade G is
32、applicable to general domestic situations where users are expected to exercise care. Grade H units are for locations where heavy use is foreseen or where the users are liable to fail to exercise care. 5 Range of assemblies and worktops For a range of assemblies to be described as conforming to grade
33、 G or grade H, all of the parts of the range shall conform to the same grade, i.e. grade G or grade H, as appropriate. If a range of assemblies is to be tested the following assemblies shall be submitted for test: a) the longest peninsular unit; b) the breakfast bar with the longest span; c) the bre
34、akfast bar with the greatest cantilevered projection; d) the longest peninsular unit that is attached only to a wall; e) the worktop with the greatest cantilevered projection; f) the overhead unit door whose geometry creates the greatest bending moment on the hinge. 6 Performance 6.1 General Individ
35、ual units within peninsular and island units and breakfast bars shall conform to BS 6222-2. When tested in accordance with Annex B and Annex C none of the following defects shall affect the strength or function of the unit or component: a) a fracture of any member, joint or component; b) any looseni
36、ng of joints intended to be rigid; c) deformation or wear of any component; d) loosening of any components. 6.2 Components 6.2.1 Peninsular and island units shall be tested by the methods given in Annex B and breakfast bars by the methods given in Annex C to the test levels of either grade G or grad
37、e H given in Table 1, Table 2 and Table 3 and shall conform to 6.1. When tested in accordance with B.3, at the appropriate grade, shelves and the bottoms and tops of assemblies shall not deflect by greater than span/200 for particle board, span/150 for wood or span/100 for other materials. 6.2.2 Whe
38、n tested in accordance with B.1, to the test levels specified for grade G or grade H in Table 2, pivoted doors on overhead units shall conform to 6.1.

42、e following information shall be made available by the manufacturer for reference by the purchaser at the point of sale: a) the name, trademark and other means of identification of either the UK manufacturer, UK distributor or UK retailer; b) description or name of the range of assemblies of which i
43、t is part (if applicable); c) the number and date of this British Standard, i.e. BS 6222-5:19951), indicating that it refers to only the strength requirements; d) the grade, i.e. grade G or grade H; e) a list of the types of assembly from the range that has been tested (if applicable). An example of
44、 suitable wording is “The strength of this assembly conforms to grade G of BS 6222-5:1995”. 8 Samples for tests Each sample assembly submitted for test shall be representative of the production assembly in all respects. Ranges of assemblies shall be tested in accordance with clause 5. 9 General requ
45、irements for tests 9.1 Inspection before and after testing Each assembly shall be inspected before it is tested. Any defects in the members, joints or attachments of components shall be noted so that they are not attributed to the effects of the tests when the tests have been completed. Before each
46、test all screws shall be tight and, if necessary, adjustable hinges shall be adjusted to function correctly. Immediately after completion of the tests, the assembly shall again be inspected thoroughly for any apparent defects and changes that have taken place since the initial inspection. 9.2 Test l
47、oading and measurements The tests shall be carried out by means of either loads or forces. NOTEFor practical purposes, a force of 10 N may be taken as equal to the downward force exerted by a mass of 1 kg. All loads and forces shall be to an accuracy of 0.5 % unless otherwise stated. All linear meas
48、urements shall be to an accuracy of 0.5 mm unless otherwise stated. 9.3 Moisture content and conditioning Before the tests are commenced, the assembly shall be sufficiently old to ensure that all component materials have developed their full strength. At least four weeks in normal conditions shall e
49、lapse from manufacture in the case of glued joints in timber, plastics moulded parts, etc. Parts made of timber products shall be checked with an electric moisture meter to ensure that the moisture content is between 8 % and 12 %. If the moisture content is above 12 %, the article shall be allowed to dry out in a warm, ventilated room until the moisture content is between 8 % and 12 %. If a standard atmosphere is required for conditioning or testing, that atmosphere shall be a temperature of (23 3) C and a relative humidity of (50 5
