IEC/PAS 60127-8:2014(E) relates to fuse resistors with particular overcurrent protection rated up to 500 V a.c. and/or 500 V d.c. for printed circuits and other substrate systems, used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors. It does not apply to fuse resistors with particular overcurrent protection for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere. The object of this PAS is: – to establish uniform requirements for fuse resistors with particular overcurrent protection so as to protect appliances or parts of appliances in the most suitable way; – to define the performance of the fuse resistors with particular overcurrent protection, so as to give guidance to manufacturers of electrical appliances and electronic equipment and to ensure replacement of fuse resistors with particular overcurrent protection by those of similar dimensions and characteristics; – to define methods of testing. This PAS applies in addition to the requirements of IEC 60127-1. Keywords: resistors with particular overcurrent protection, protection of electric appliances, electronic equipment and component parts
