This part of IEC 60127 covers the general requirements and tests applicable to all types ofminiature fuse-links (e.g. cartridge fuse-links, sub-miniature fuse-links and universal modularfuse-links) for the protection of electric appliances, electronic equipment and component partsthereof normally intended to be used indoors.Specific details covering each major subdivision are given in subsequent parts.This standard does not apply to fuses for appliances intended to be used under specialconditions, such as in a corrosive or explosive atmosphere.The object of this standard isa) to establish uniform requirements for miniature fuses so as to protect appliances or partsof appliances in the most suitable way,b) to define the performance of the fuses, so as to give guidance to designers of electricalappliances and electronic equipment and to ensure replacement of fuse-links by those ofsimilar dimensions and characteristics,c) to define methods of testing,d) to define maximum sustained dissipation of fuse-links to ensure good compatibility ofstated power acceptance when used with fuse-holders according to this standard (seeIEC 60127-6).
