33、on of electronic equipment has caused users to require fuse-links of small dimensions, and of appropriate design for application to printed circuit boards or other substrate systems, possibly by automatic means. These fuse-links should be designed to incorporate a degree of non-interchangeability. R
34、ated voltages of 32 V, 63 V, 125 V, and 250 V are specified together with the following characteristics: very quick acting (FF), quick acting (F), time-lag (T) and long time-lag (TT). Because of the increasing importance of limitation of transient overvoltages in new technology, recommendations are
35、included for limits to the overvoltages produced by these fuses under specified test conditions related to typical circuit configurations. The option is given to specify the breaking capacity with alternating current or direct current; it is considered that fuses that meet the d.c. requirement will
36、meet the a.c. requirement; however, testing is required to validate this. Fuses may be dual rated, in which case the manufacturers literature should be referred to. The users of miniature fuses express the wish that all standards, recommendations and other documents relating to miniature fuses shoul
37、d have the same publication number in order to facilitate reference to fuses in other specifications, for example, equipment specifications. Furthermore, a single publication number and subdivision into parts would facilitate the establishment of new standards, because clauses and subclauses contain
38、ing general requirements need not be repeated. The new IEC 60127 series is thus subdivided as follows: The fourth part of this standard covers additional requirements, test equipment and standard sheets for UMFs. It should be read in conjunction with other parts of the IEC 60127 series. IEC 60127, M

Additional requirements and test equipment 1 Scope and object 1.1 This part of IEC 60127 relates to Universal Modular Fuse-links (UMF) for printed c
42、ircuits 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-links for appliances intended to be used under special conditions, such as in a corrosive or explosi
43、ve atmosphere. These fuses are normally intended to be mounted or replaced only by appropriately skilled persons using specialized equipment. Fuse-links for use in fuse-holders are under consideration. This standard applies in addition to the requirements of IEC 60127-1. 1.2 The objects of this part
44、 of IEC 60127 are as given in IEC 60127-1, with the additional requirement of a degree of non-interchangeability. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60127. At the time of publica
45、tion, the editions indicated were valid. All normative documents are subject to revision and parties to agreements based on this part of IEC 60127 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
