6、I 20 August 2003 National foreword This British Standard has been prepared by Subcommittee PEL/32/3 (formerly PEL/78/3). It is the official English language version of EN 60127-6:1994 Miniature fuses Part 6: Fuse-holders for miniature cartridge fuse-links, including amendments A1:1996 and A2:2003, p

7、ublished by the European Committee for Electrotechnical Standardization (CENELEC). It is identical with IEC 60127-6:1994 including amendments 1:1996 and 2:2002, published by the International Electrotechnical Commission (IEC). This British Standard is one of a series. The other Parts, which together

8、 superseded BS 4265 in 1991, are as follows. BS EN 60127-1, Definitions for miniature fuses and general requirements for miniature fuse-links. BS EN 60127-2, Specification for cartridge fuse-links. BS EN 60127-3, Specification for sub-miniature fuse-links. BS EN 60127-5, Guide for the quality assess

9、ment of miniature fuse links. It is expected that IEC 60127-4 will be approved by CENELEC as EN 60127-4. For the purposes of this British Standard, any references to IEC page numbers in the text should be ignored. This publication does not purport to include all the necessary provisions of a contrac

10、t. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

39、y the users of miniature fuses, all standards, recommendations and other documents relating to miniature fuses should have the same publication number in order to facilitate reference to fuses in other specifications, for example, equipment specifications. Furthermore, a single publication number an

40、d subdivision into parts would facilitate the establishment of new standards, because clauses and subclauses containing general requirements need not be repeated. The new IEC 60127 series is thus subdivided as follows: IEC 60127, Miniature fuses (general title). IEC 60127-1, Part 1: Definitions for

41、miniature fuses and general requirements for miniature fuse-links. IEC 60127-2, Part 2: Cartridge fuse-links. IEC 60127-3, Part 3: Sub-miniature fuse-links. IEC 60127-4, Part 4: Universal modular fuse-links (UMF). IEC 60127-5, Part 5: Guidelines for quality assessment of miniature fuse-links. IEC 60

42、127-6, Part 6: Fuse-holders for miniature cartridge fuse-links. IEC 60127-7, (Free for further documents). IEC 60127-8, (Free for further documents). IEC 60127-9, Part 9: Test-holders and test circuits. IEC 60127-10, Part 10: User guide. This Part of IEC 60127 covers requirements, test equipment and

43、 test methods for fuse-holders. It is a self-standing document, which refers back to Part 1 with regard to certain definitions and the atmospheric conditions for test. It also makes reference to other parts of IEC 60127 with regard to dimensions and maximum power losses of fuse-links. 1 Scope and ob

44、ject 1.1 This Part of IEC 60127 is applicable to fuse-holders for miniature cartridge fuse-links according to IEC 60127-2 and sub-miniature fuse-links according to IEC 60127-3 for the protection of electric appliances, electronic equipment and component parts thereof, normally intended for use indoo

Examples of fuse-holder types with different features are given in Table 1.EN 60127-6:1994 6 BSI 20 August 2003 Table 1 Features of unexposed or exposed fuse-holders This standard applies to fuse-holders with: a maximum rated current of 16 A; and a maximum rated voltage of 1 500 V d.c. or 1 000

46、V a.c.; and for use up to 2 000 m above sea-level, unless otherwise specified. 1.2 The object of this standard is to establish uniform requirements for safety and the assessment of electrical, mechanical, thermal and climatic properties of fuse-holders and the compatibility between fuse-holders and
