2、 Copy, (c) BSI DD CEN/TS 15023-3:2006 This Draft for Development was published under the authority of the Standards Policy and Strategy Committee on 31 January 2007 BSI 2007 ISBN 978-0-580-49912-8 National foreword This Draft for Development was published by BSI. It is the UK implementation of CEN/T
3、S 15023-3:2006. 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. It should be applied on this provisional basis, so that information and experience of its practical application can be
4、obtained. Comments 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 to a European standard. A review of this publication will be initiated not later than 3 years after its publication by
5、 the European organization so that a decision can be taken on its status. Notification 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
6、 decide whether to support the conversion into a European Standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent to the Secretary of the responsible BSI Technical Committee at British Standards House, 389 Chiswick High Road, London W4 4AL. The UK parti
7、cipation in its preparation was entrusted to Technical Committee NFE/34, Copper and copper alloys. A list of organizations represented on NFE/34 can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible

10、AF) Kupfer und Kupferlegierungen - Bestimmung des Nickelgehaltes - Teil 3: Flammenatomabsorptionsspektrometrisches Verfahren (FAAS) This Technical Specification (CEN/TS) was approved by CEN on 12 September 2006 for provisional application. The period of validity of this CEN/TS is limited initially t
11、o three years. After two years the members of CEN will be requested to submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard. CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/
12、TS available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.
