IEC 60127-8:2018

This part of IEC 60127 relates to fuse resistors with particular overcurrent protection rated upto AC 500 V and/or DC 500 V for printed circuits and other substrate systems, used for theprotection of electric appliances, electronic equipment and component parts thereof, normallyintended to be used indoors.It does not apply to fuse resistors with particular overcurrent protection for appliancesintended to be used under special conditions, such as in a corrosive or explosive atmosphere.The object of this part of IEC 60127 isa) to establish uniform requirements for fuse resistors with particular overcurrent protectionso as to protect appliances or parts of appliances in the most suitable way;b) to define the performance of the fuse resistors with particular overcurrent protection, so asto give guidance to manufacturers of electrical appliances and electronic equipment and toensure replacement of fuse resistors with particular overcurrent protection by those ofsimilar dimensions and characteristics;c) to establish uniform test methods for fuse resistors with particular overcurrent protection,so as to allow verification of the values (for example rated dissipation, functioningcharacteristic and rated breaking capacity values) specified by the manufacturer.Manufacturers of fuse resistors with particular overcurrent protection shall ensure on theirown responsibility that their products comply with the requirements of the resistor-relatedstandards IEC 60115-1, IEC 60115-4-101 and IEC 60115-4-1021.This part of IEC 60127 applies in addition to the requirements of IEC 60127-1.
