4、 60051-1:1999 Comments National foreword This British Standard is the English language version of EN 60051-1:1998. It is identical with IEC 60051-1:19!37. It supersedes BS 89-1:1990 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee PEL85, Measuring equi
5、pment for electrical and electromagnetic quantities, which has the responsibiiity to: - aid enquirers to understand the text; - present to the responsible intedonalA3uropean committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed - monitor related i
6、nternational and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Rom 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered
7、as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to int
8、ernational publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “international Standards Correspondence Index”, or by using the “Find faci

CENELEC members are bound to comply with the CENICENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without
15、 any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language
16、made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.

39、ect acting indicating electrical measuring instruments having an analogue display, such as: - ammeters and voltmeters; - wattmeters and varmeters; - frequency meters of pointer and vibrating-reed types; - phasemeters, power-factor meters and synchroscopes; . - ohmmeters, impedance meters and conduct
40、ance meters; - multi-function instruments of the above types. It also applies to certain accessories used with these instruments, such as: - shunts; - series resistors and impedance elements. If other accessories are associated with instruments, this standard is applicable to the combination of the
41、instrument and the accessory provided that the adjustments have been made for the combination. This standard also applies to a direct acting indicating electrical measuring instrument whose scaie marks do not correspond directly to its electrical input quantity, provided that the relationship betwee
42、n them is known. This standard also applies to instruments and accessories having electronic devices in their measuring and/or auxiliary circuits. This standard does not apply to special purpose instruments which are covered by their own IEC standards. This standard does not apply to special purpose
43、 devices which are covered by their own IEC standards when they are used as accessories. This standard does not contain either requirements for protection against environmental conditions or the relevant tests. However, when necessary, and then only by agreement between the manufacturer and the user
44、, tests to approximate the conditions of use may be selected from IEC 60068. This standard does not specify requirements concerning dimensions of instruments or accessories (for the former, see IEC 60473).
