BRITISH STANDARD BS EN 12058:2004 Natural stone products Slabs for floors and stairs Requirements The European Standard EN 12058:2004 has the status of a British Standard ICS 91.100.15 ? Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 16:35:45 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 12058:2004 This British Standard, was published under the authority of the Standards Policy and Strategy Committee on 6 January 2005 © BSI 6 January 2005 ISBN 0 580 45198 4 National foreword This British Standard is the official English language version of EN 12058:2004. EN 12058:2004 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandates M/119, Flooring, and M/121, Internal and external wall and ceiling finishes, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 12058 as a “harmonized” European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. The Commission in consultation with Member States has agreed a transition period for the co-existence of “harmonized” European Standards and their corresponding national standard(s). It is intended that this period will comprise a period, usually nine months, after the date of availability of the European Standard, during which any required changes to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. EN 12058:2004 is the subject of transitional arrangements agreed under the Commission mandate. In the UK, there are no corresponding national standards. The UK participation in its preparation was entrusted to Technical Committee B/545, Natural stone, which has the responsibility to: A list of organizations represented on this committee can be obtained on request to its secretary.
