7、art of BS 6222 is published by BSI Standards Limited, under licence from The British Standards Institution, and came into effect on 31 July 2017. It was prepared by Subcommittee FW/0/2, Domestic and contract furniture, under the authority of Technical Committee FW/0, Furniture. A list of organizatio

8、ns represented on these committees can be obtained on request to their secretary.SupersessionThis part of BS 6222 supersedes BS 62223:1999, which is withdrawn.Information about this documentThis part of BS 6222 represents a full revision of the standard and incorporates the following key changes: up

9、date of normative references to reflect the most current test standards; removal of the classification of surfaces; removal of the selection criteria; removal of the requirement for a laminate sheet to conform to BS EN 4381; restructuring of the layout of performance requirements for ease of use; re

10、moval of the resistance to edge impact test and requirements; and removal of test for peel and shrinkage of foils and requirements.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal

11、auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Requirements in this standard are drafted in accordance with Rules for the structure and drafting of UK standards, subclause G.1.1, whic

12、h states, “Requirements should be expressed using wording such as: When tested as described in Annex A, the product shall .”. This means that only those products that are capable of passing the specified test will be deemed to conform to this standard.Where words have alternative spellings, the pref

13、erred spelling of the Shorter Oxford English Dictionary is used (e.g. “organization” rather than “organisation”).Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance w

14、ith a British Standard cannot confer immunity from legal obligations.BS 62223:2017 BRITISH STANDARDII THE BRITISH STANDARDS INSTITUTION 2017 ALL RIGHTS RESERVED1 ScopeThis part of BS 6222 specifies performance requirements for durability of surface finishes for panel materials and fascias used in do
