7、hnical Committee TCT/7, Telecommunications Installation requirements.A list of organizations represented on these committees can be obtained onrequest to their secretary.SupersessionThis British Standard supersedes BS 6701:2010, which is withdrawn.Information about this documentThis is a full revisi
8、on of BS 6701 and has been published to supportBS EN 50174-1:2009+A2:2014, BS EN 50174-2:2009+A2:2014 andBS EN 50174-3:2013 which contain text that was previously in BS 6701:2010. Itshould be read in conjunction with the BS EN 50174 series of standards. It alsocontains information regarding the use
9、of telecommunications cabling for thepowering of telecommunications and other equipment.Unless otherwise stated in this standard, voltages and currents are r.m.s. with anominal frequency of 50 Hz.Hazard warningsWARNING. This British Standard calls for the use of substances and/or proceduresthat can
10、be injurious to health if adequate precautions are not taken. It refersonly to technical suitability and does not absolve the user from legal obligationsrelating to health and safety at any stage.Use of this documentIt has been assumed in the preparation of this British Standard that theexecution of
11、 its provisions will be entrusted to appropriately qualified andexperienced people, for whose use it has been produced.The requirements contained within Clause 4 are primarily for owners of premiseshousing telecommunications systems, who may delegate selected responsibilitiesto designers, specifiers
12、, operators and maintainers of installedtelecommunications equipment and telecommunications cabling.The requirements contained within Clause 5 are primarily for the installers oftelecommunications equipment and telecommunications cabling.Users of this British Standard should ensure that they are rea
13、ding the clauseappropriate to their responsibilities.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrequirements are expressed in sentences in which the principal auxiliary verb is“shall”.Commentary, explanation and general informative materi
14、al is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of acontract. Users are responsible for its correct application.Compliance with a British Standard cannot c
