10、 in the text by tags !“.The series of standards includes product and facility specifications giving particular requirements for individual items of apparatus and facilities, together with standards covering general requirements for the connection of apparatus to the various public telecommunication

11、systems (i.e. any telecommunication system designated as a public telecommunication system by an order made under Section 9 of the Telecommunication Act 1984).The requirements specified in the standards are intended to ensure that apparatus conforming to them, when connected to public telecommunicat

12、ion systems, will neither adversely affect any such system, nor interfere with the service available to other users of the systems.The standards include certain safety requirements that are only for the protection of personnel operating the public telecommunication system and others that are for the

13、 protection of users from hazards that may arise from the connection of the apparatus to that system.BS 6312:1985 has been revised and re-numbered as BS 6312-1:1994 and is published with a new Part 2 which comprises two separate Sections.BS 6312 covers the generic subject of connectors for analogue

14、telecommunication interface purposes.BS 6312-1 specifies the requirements for plugs. BS 6312-2 specifies the requirements for sockets for use with plugs specified in BS 6312-1.There are two Sections of Part 2.Section 2.1 Specification for sockets General requirementsSection 2.2 Specification for par

In particular, attention is drawn to the Telecommunications Act 1984.Summary of pagesThis document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 16, an inside back cover and a back cover.The BSI copyright notice displayed in this document indicates when t

17、he document was last issued.ForewordThis Section of BS 6312-2 has been prepared under the direction of the Telecommunications Standards Policy Committee. It forms one of a series of British Standards that are being produced following the commencement of liberalization in October 1981 of the supply o

18、f certain telecommunications BSI 24 August 2005BS 6312-2-2.2:19971 ScopeThis Section of BS 6312-2 specifies the requirements and tests necessary to ensure the safety and the dimensional interchangeability of fixed socket-outlets, as defined in 3.2, intended for connection to telecommunications wirin

19、g.Such socket-outlets may be classified both by function, i.e. as being either primary (surge protected or unprotected) or secondary, and according to their method of mounting, i.e. as surface, flush and panel mounted socket-outlets.This Section does not apply to sockets incorporated in apparatus.So

20、cket-outlets conforming to this standard are intended to be suitable for use under the following conditions of service unless otherwise specified: an ambient temperature in the range 5 C to +35 C, the average value over a 24 h period not exceed-ing 25 C; a situation not subject to direct radiation f

21、rom the sun or other source of heat likely to raise temper-atures above the limits specified above; an atmosphere not subject to excessive pollution by smoke, chemical fumes, rain, spray, prolonged or high humidity or other abnormal conditions.NOTE Socket-outlets conforming to this standard may be s

22、uitable for use in other conditions subject to agreement between manufacturer and user. Information given in a manufacturers catalogue may take the place of such an agreement.This standard applies in conjunction with BS 6312-2.1 and the requirements are in addition to those in that standard.Requirem

23、ents for electromagnetic compatibility are not given as socket-outlets do not in themselves produce extraneous emissions, nor is their functioning affected by external emissions. Therefore no emission or immunity tests are necessary.2 References2.1 Normative referencesThis British Standard incorpora

24、tes, by dated or undated reference, provisions from other publications. These normative references are made at the appropriate places in the text and the cited publications are listed on the inside back cover. For dated references, only the edition cited applies; any subsequent amendments to, or rev

25、isions of, the cited publication apply to this British Standard only when incorporated in the reference by amendment or revision. For undated references, the latest edition of the cited publication applies, together with any amendments.2.2 Informative referencesThis British Standard refers to other

36、in the order specified in 6.2. The tests shall be made either by the manufacturer, or the responsible vendor, or by any competent testing laboratory or certification authority. The results of such tests shall be recorded and retained for reference and inspection. Where no test method is specified, c

37、onformity shall be checked by inspection and, where appropriate, by measurement.6.2 A total of at least nine specimens of socket-outlet, of any one type, shall be submitted to inspection and tests against the requirements of the following clauses:a) three specimens of socket-outlet: Clauses 7, 8, 9,

38、 10 and 12 (visual inspection and manual examination);b) three specimens of socket-outlet: Clauses 10, 11, 13 and 14 (general tests);c) three specimens of socket-outlet: Clause 15 (material tests).NOTE If any particular test has to be repeated, as part of the normal sequence, this requirement is spe

39、cified in the appropriate test clause.6.3 Unless otherwise specified in this standard, the socket-outlets shall be tested (as delivered by the supplier) under the conditions specified in 4.2 of BS 6312-2.1:1994.Socket-outlets used for the tests shall be identical to normal production items in respec

40、t of all details which may affect the test results.Socket-outlets shall be deemed to conform if no socket-outlet fails in the complete series of tests given in 6.2.If one socket-outlet fails in any group in the complete series of tests specified in 6.2, socket-outlets of that type shall be deemed to

41、 have failed to conform to this standard, unless that socket-outlet can be shown to be unrepresentative of normal production or design, in which case a further set of socket-outlets shall be submitted to the test or tests in that group. If there is no failure in this retest then socket-outlets of th

42、at type shall be deemed to conform to this standard.If more than one socket-outlet fails in the complete series of tests given in 6.2 then socket-outlets of that type shall be deemed to have failed to conform to this standard.7 Construction7.1 The minimum size of flush socket-outlet plates construct
