What is BS EN 60127-7‒ Miniature fuse links for special applications about?
BS EN 60127-7 is the seventh part of an international multi-series standard that covers guidelines for miniature fuse links for special applications.
BS EN 60127-7 is applicable 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.
BS EN 60127-7 provides guidelines and limits that are usually acceptable for quality control purposes by large-scale users and manufacturers of miniature fuse-links. It gives specifications like terms, definitions, general requirements, standard ratings, markings, general notes on tests, as well standard sheets for miniature fuse-links for special applications.
Note 1: BS EN 60127-7 does not apply to miniature fuse-links for appliances intended to be used under special conditions, such as in corrosive or explosive atmospheres.
Who is BS EN 60127-7‒ Miniature fuse-links for special applications for?
BS EN 60127-7 on miniature fuse-links for special applications is useful for:
- Manufacturers and suppliers of miniature fuses
- Dealers and distributors of miniature fuses
- Designers of miniature fuses
- Test/ service providers for miniature fuses
Why should you use BS EN 60127-7‒ Miniature fuse-links for special applications?
Miniature fuses are tiny instruments that are relatively small in physical size but have a wide range of diverse applications. As these switches play a key role in the safety of several instruments, it’s essential to perform the quality assessment of miniature fuses, periodically.
BS EN 60127-7 provides you with effective methods for checking the quality and efficiency of miniature fuse-links that are used in special applications. It establishes uniform test methods that guide you to verify the values and performance aspects, serving the purpose of quality control of the miniature fuse-links according to the requirements from the global standards.
The users of BS EN 60127-7 also get recommendations as well as information for documents relating to miniature fuses so that, they have the same publication number in order to facilitate reference to fuses in other specifications, for example, equipment specifications, etc.
What’s changed since the last update?
BS EN 60127-7:2016 supersedes BS EN 60127-7:2013, which is withdrawn. BS EN 60127-7:2016 includes the following significant technical changes with respect to the previous editions:
