13、.BRITISH STANDARDBS 8201:2011ii BSI 2011ForewordPublishing informationThis British Standard is published by BSI and came into effect on30 October 2011. It was prepared by Technical Committee B/543, Round andsawn timber. A list of organizations represented on this committee can beobtained on request
14、to its secretary.SupersessionThis British Standard supersedes BS 8201:1987, which is withdrawn.Information about this documentThis British Standard includes recommendations relating to the work involved inlaying flooring and illustrates some typical constructions on which it may be laid.This is a fu
15、ll revision of the standard, and introduces the following principalchanges: information and recommendations have been rationalized in considerationof current best practice; new materials and product availability; materials are included in a new Section 2; and details provided are now in relation onl
16、y to wood and wood-based panelsinstalled as, or as a component part of, finished wood flooringGeneral recommendations applicable to all types of wood flooring are containedwithin Section 1, Section 2, Section 3 and Section 9, with recommendationsspecific to individual types of flooring given in Sect
17、ions 4 to 8 . Because somerecommendations are applicable to more than one individual type of floor, thisinvolves some repetition. It was considered that a limited degree of repetition toensure reasonable completeness of each section would be preferable toexcessive cross-referencing.Annex A describes
18、 the test method for use in conjunction with therecommendations given in 12.4.6.Increasingly, in addition to material selection based on performance capabilities,suitability and appearance, consideration is being given to the specification ofwood and wood products with regard to legality and sustain
19、ability of source.Whilst this aspect of material specification is not within the remit of BritishStandards (this might be set to change with the desire of the EuropeanCommission to see environmental criteria included in EN product standards) thecommittee believe it to be of sufficient importance tha
20、t reference to provisionsbeing made in the UK to address this issue is included in the new Annex B.Use of this documentAs a code of practice, this British Standard takes the form of guidance andrecommendations. It should not be quoted as if it were a specification andparticular care should be taken
21、to ensure that claims of compliance are notmisleading.Any user claiming compliance with this British Standard is expected to be able tojustify any course of action that deviates from its recommendations.It has been assumed in the preparation of this British Standard that theexecution of its provisio
22、ns will be entrusted to appropriately qualified andexperienced people, for whose use it has been produced.BRITISH STANDARD BS 8201:2011 BSI 2011 iiiPresentational conventionsThe provisions in this standard are presented in roman (i.e. upright) type. Itsrecommendations are expressed in sentences in w
23、hich the principal auxiliaryverb is “should”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of acont
24、ract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.BRITISH STANDARDBS 8201:2011iv BSI 2011Section 1: GeneralIntroductionThis British Standard gives recommendations and guidance on the material,environment and instal
25、lation variables that in combination have a fundamentaleffect on the achievement of satisfactory performance and serviceability offinished wood flooring.The content of the document has been modified to reflect more appropriatelywood and wood-based panels installed as finished flooring and, of necess
26、ity, asunderlayment for finished wood flooring but not for subsequent installation ofcarpet or resilient flooring.The installation and use of wood-based panels as primarily a load-bearingsurface has been cross referenced to BS 8103-3.The words “timber” and “wood” in this British Standard cover softw
27、oods,hardwoods and wood-based panels, as appropriate in the context.1 ScopeThis British Standard gives recommendations for laying the following types offlooring:a) board;b) pre-assembled board;c) strip;d) mosaic;e) overlay;f) parquet;g) block;h) end grain flooring;i) multi-layer; andj) wood-based pa
28、nels.This British Standard does not cover the protection afforded to a floor by floorcoverings or surface finishes.This British Standard does not cover floors for temporary structures or floorsintended for limited use. Different considerations might apply to these floors.NOTE For laminate flooring,
29、see BS 8425.Bamboo flooring is also not covered by this British Standard.The hygrometer test for dampness of concrete bases is given in Annex A.Guidance on the selection of wood species is given in Annex B.2 Normative referencesThe following referenced documents are indispensable for the application
