GB/T 9364.7-2016
Scope
This part of GB/T 9364 specifies the terms and definitions, general requirements, standard ratings, marking, testing, size and structure, electrical performance and other technical requirements of small fuse-links for special applications, as well as standard specification sheets. This section applies 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. This section does not apply to fuses that are fully covered in the subsequent parts of GB 13539.1. This standard does not apply to fuses for electrical installations intended to be used under special conditions (for example, corrosive or explosive atmospheres). Small fuse-links for special applications are not expected to be replaced by end users of electrical installations and electronic equipment. The purpose of this section is to develop a unified test program for special applications of small fuse-links, in order to achieve the verification of the data given by the manufacturer (for example, melting time and breaking capacity data).
