1、DRAFT FOR DEVELOPMENT DD CEN/TS 13810-2:2003 Wood-based panels Floating floors Part 2: Test methods ICS 79.060.01 DD CEN/TS 13810-2:2003 This Draft for Development was published under the authority of the Standards Policy and Strategy Committee on 20 August 2003 BSI 20 August 2003 ISBN 0 580 42486 3
2、 National foreword This Draft for Development is the official English language version of CEN/TS 13810-2:2003. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because it is a new test
3、and there is insufficient experience of its use in the majority of CEN National Members. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments arising from the use of this Draft for Development are requested so that
4、UK experience can be reported to the European organization responsible for its conversion to a European standard. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken on its status at the end of its 3-year life. Not
5、ification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European standard, to extend
6、 the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Technical Committee B/541, Wood-based panels, at British Standards House, 389 Chiswick High Road, London W4 4AL, giving the document reference and clause number and proposing, where
7、 possible, an appropriate revision of the text. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement European publications referred to in this document may be found in the BSI Catalogue under the sec
8、tion entitled “International Standards Correspondence Index”, or by using the “Search” facility of the BSI Electronic Catalogue or of British Standards Online. Summary of pages This document comprises a front cover, an inside front cover, the CEN/TS title page, pages 2 to 15 and a back cover. The BS
