6、n . 9 Page 3 TR 4732:11-2015 (E) Foreword The main task of ASD-STAN is to prepare EN standards. In exceptional circumstances, however, the publication of a Technical Report of one of the following types may be proposed: type 1, the subject is still under technical development requiring wider exposur
7、e; type 2, a Technical Domain has collected data of a different kind from that which is normally published as a European Standard. The Electrical Domain decided to publish this document in the form of a Technical Report of type 2, as it contains only general guidelines. Page 4 TR 4732:11-2015 (E) In
8、troduction The aim of this Technical Report is to describe applicable test methods for alternative plating validation for connectors and accessories. 1 Scope This Technical Report specifies necessary tests and methods to validate alternative plating compatible with cadmium and chromium VI existing p
