This part of IEC 60127 covers requirements for miniature fuse-links for special applications. It does not apply to fuses completely covered by the subsequent parts of IEC 60269-1. It does not apply to miniature fuse-links for appliances intended to be used under special conditions@ such as in corrosive or explosive atmospheres. This standard applies in addition to the requirements of IEC 60127-1. This standard is applicable to fuse-links with a rated voltage not exceeding 1000 V@ a rated current not exceeding 20 A and a rated breaking capacity not exceeding 50 kA. Miniature fuse-links for special applications are not intended to be replaced by the end-user of an electrical / electronic appliance. The object of this standard is to establish uniform test methods for miniature fuse-links for special applications@ so as to allow verification of the values (for example melting time and breaking capacity values) specified by the manufacturer.
