2、 (c) BSI DD CLC/TS 50430:2005 This Draft for Development was published under the authority of the Standards Policy and Strategy Committee on 23 February 2005 BSI 23 February 2005 ISBN 0 580 45568 8 National foreword This Draft for Development is the official English language version of CLC/TS 50430:
3、2005. 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 the technology is still at a developmental stage. It should be applied on this provisional basis, so that information and
4、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 conversion to a European Standard. A review of this publication will be initiated
5、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 appropriate issue of Update Standards. According to the replies received by th
6、e 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 sent in writing to the Secretary of BSI Subcommittee GEL/86/1, Optical fibres and
7、cables, at 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 organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references The British Sta

28、t covers gas pipe cables and sub-ducts for installation by blowing and/or pulling / dragging in high pressure gas pipes. Systems built with components covered by this standard are subject to the requirements of sectional specifications EN 60794-3 and EN 60794-4 where applicable. Gas pipe cable and s
29、ub-duct constructions have to meet the different requirements of the gas- companies and/or associations regarding chemical, environmental, operational interactions and in general maintenance conditions. A table of preferential applications, describing gas pipe cable characteristics versus methods of
30、 installation is reported in Annex A for high pressure gas pipe cables. Clause 4 describes a blank detail specification for gas pipe cables and sub-ducts for installation by blowing and/or pulling / dragging in/into high pressure gas pipes. It incorporates some minimum requirements. Detail specifica
31、tions may be prepared on the basis of this family specification. The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance criteria should be interpreted with respect
32、 to this consideration. The number of fibres tested is representative of the sewer cable and should be agreed between the customer and supplier. 2 Normative references The following referenced documents are indispensable for the application of this document.
