2、d Strategy Committee on 10 September 2003 BSI 10 September 2003 ISBN 0 580 42591 6 National foreword This Draft for Development is the English language version of CEN/TS 13763-27:2003. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development serie
3、s of publications and is of a provisional nature because electronic initiation systems are a recent innovation and the testing procedures are not fully developed. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments
4、 arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion into a European Standard. A review of this publication will be initiated 2 years after its publication by the European organization so t
5、hat a decision can be taken on its status at the end of its three-year life. The commencement of the review period will be notified by an announcement in Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support
6、the conversion into a European Standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Technical Committee CII/61, Explosives for civil uses, at 389 Chiswick High Road, London W4 4AL, giving the document reference and
7、clause number and proposing, where 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 international or European publications referred to in this docum
