1、DRAFT FOR DEVELOPMENT DD CEN/TS 14507-1:2003 Inhalational nitric oxide systems Part 1: Delivery systems ICS 11.040.10 DD CEN/TS 14507-1:2003 This Draft for Development was published under the authority of the Standards Policy and Strategy Committee on 11 April 2003 BSI 11 April 2003 ISBN 0 580 41536

2、 8 National foreword This Draft for Development reproduces verbatim CEN/TS 14507-1:2003. 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 nitric oxide is a relatively new medica

3、l gas. 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 UK experience can be reported to the European organization responsible for its con

4、version 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. Notification of the start of the review period will be made in an announcement in the

5、 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 the life of the Technical Specification or to withdraw it. Comments should be sen

6、t in writing to the Secretary of BSI Subcommittee CH/121/1, Breathing attachments and anaesthetic machines, at British Standards House, 389 Chiswick High Road, London W4 4AL, giving the document reference and clause number and proposing, where possible, an appropriate revision of the text. A list of

7、 organizations represented on this committee can be obtained on request to its secretary.
