This standard gives a guide for tests for assessing the quality of miniature fuse-links other than type tests, for the case where there is no complete agreement between the user and the manufacturer on what such tests should be. To provide guidelines and limits generally acceptable for quality control purposes by large scale users and manufacturers of miniature fuse-links. This standard has validity for large scale series with lot sizes of 10000 and more. It is also applicable for smaller lot sizes, if necessary. Periodic inspections by reduced type tests (Clause 5) are intended to be carried out periodically in order to ensure that the level of technical performance previously verified by complete type tests as given in subsequent parts of IEC 60127 is maintained. The frequency of periodic in relation to lot-by-lot inspections is not established in this standard.
