    • BS 6431-1:1983 National foreword This Part of this British Standard has been prepared under the direction of the Clay Products Standards Committee and is the English language version of EN 87:1991 “Ceramic floor and wall tiles. Definitions, classification, characteristics and marking” published by the European Committee for Standardization (CEN). EN 87 was produced as a result of international discussion in which the UK took an active part. Attention is drawn to the use in this standard of the comma as a decimal marker. This is to accord with European practice, but it should be noted that it is current practice in British Standards to use a full point on the baseline as a decimal marker. Additional information. It is unlikely that standards for the group C tiles, made by a cast process, will be published as there is now only a small production of this type in Europe. When marking or specifying a product (see 6.1 and 6.2) the manufacturer may mark or specify by reference to either the European Standard or the British Standard. A British Standard does not purport 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 cover, pages i and ii, the EN title page, pages 2 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.ii © BSI 07-1999

Anforderungen und Kennzeichnung This European Standard was approved by CEN on 1991-07-17. CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.
