29、neral requirements and tests applicable to all types of miniature fuse-links (e.g. cartridge fuse-links, sub-miniature fuse-links and universal modular fuse-links) for the protection of electric appliances, electronic equipment and component parts thereof normally intended to be used indoors. Specif

30、ic details covering each major subdivision are given in subsequent parts. This standard does not apply to fuses for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere. The object of this standard is a) to establish uniform requirements for miniatu

31、re fuses so as to protect appliances or parts of appliances in the most suitable way, b) to define the performance of the fuses, so as to give guidance to designers of electrical appliances and electronic equipment and to ensure replacement of fuse-links by those of similar dimensions and characteri

32、stics, c) to define methods of testing, d) to define maximum sustained dissipation of fuse-links to ensure good compatibility of stated power acceptance when used with fuse-holders according to this standard (see IEC 60127-6). 2 Normative references The following referenced documents are indispensab

33、le for the application of this document. For dated references, only the edition cited applies.
