17、9/A1 : 1996 BSI 1997 Brief history Following a request by the International Wallpaper Manufacturers Association (IGI), CEN/TC 99 was established in 1980 to develop standards for wallcoverings in roll form. The IGI submitted a first draft proposal. This was considered and developed at CEN/TC 99 meeti

18、ngs in London (1981), Paris (1982), Berlin (1983), Go teborg (1984), Manchester (1985) and Brussels (1988). This is one of three European Standards for wallcoverings so far developed; the other two being a vocabulary, EN 235, and a standard for finished wallpapers, wall vinyls and plastics wallcover

19、ings, EN 233. Still in preparation in CEN/TC 99 are standards for textile and for heavy duty wallcoverings. In accordance with the Common CEN/CENELEC Rules, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ir

26、t. They are normally relief or ingrain wallcoverings. These wallcoverings do not, in general, have as good washability and colour fastness to light before their subsequent decoration as have finished wallcoverings which are not intended to be decorated after hanging. Related European Standards on th

27、e vocabulary and symbols used in the wallcovering industry and for finished wallpapers, wall vinyls and plastics wallcoverings are also published. Other European Standards covering textile wallcoverings and heavy duty wallcoverings are in course of preparation. 1 Object and field of application This

28、 European Standard: specifies requirements for dimensions and marking; gives the symbols to be used for marking purposes, for matching, methods of application and removal; specifies the maximum permissible content of certain heavy metals, vinyl chloride monomer and formaldehyde. The marking requirem

29、ents of this standard are primarily for information of the consumer and to enable optimum use to be made of the product. This standard applies to wallcoverings for subsequent decoration supplied in rolls for hanging onto walls and ceilings by means of an adhesive covering the whole of the interface

30、between the wallcovering and the support. Excluded from this standard are rigid materials, materials not attached or not wholly attached by adhesive, finished wallpapers, wall vinyls, plastics wallcoverings, textile wallcoverings, heavy duty wallcoverings and non-decorative wallcoverings such as wal

31、l linings or those with special properties, e.g. thermal or acoustic insulation. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are placed at the appropriate places in the text and the publicati

32、ons are listed hereafter. For dated references, subsequent references to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. ISO 186 : 1985 P
