1、DRAFT FOR DEVELOPMENT DD ENV 737-6:2003 Medical gas pipeline systems Part 6: Dimensions and allocation of probes for terminal units for compressed medical gases and vacuum ICS 11.040.10; 23.040.60 DD ENV 737-6:2003 This Draft for Development was published under the authority of the Standards Policy
2、and Strategy Committee on 29 April 2003 BSI 29 April 2003 ISBN 0 580 41648 8 National foreword This Draft for Development is the English language version of ENV 737-6:2003, which is a Special Status European Prestandard. This publication is not to be regarded as a British Standard. It is being issue
3、d in the Draft for Development series of publications and is of a provisional nature because of the reasons given in the Foreword to ENV 737-6, i.e. principally to allow existing national standards for probes to continue in existence so that probes complying with the dimensions specified in those st
4、andards may continue to be used for new medical gas installations and the extension and maintenance of existing installations. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. BS 5682:1998 will remain in effect. A Specia
5、l Status European Prestandard differs from an ENV or Technical Specification by being exempt from the necessity of regular review as to suitability for its conversion into a European Standard, although such reviews can be undertaken should circumstances indicate. If such a review is undertaken in fu
6、ture, comments arising from the use of this Draft for Development will be requested so that UK experience can be reported to the European organization responsible for its proposed conversion into a European Standard. Notification of the start of any such review period will be made in an announcement
7、 in the appropriate issue of Update Standards and, according to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion of ENV 737-6 into a European Standard or to withdraw it. Comments relating to experience of the use of DD
8、ENV 737-6 should be sent in writing to the Secretary of BSI Technical Committee CH/121/6, Medical gas supply systems, at 389 Chiswick High Road, London W4 4AL, giving the document reference and clause number and proposing, where appropriate, suggestions for revision of the text.
