DIN EN 16602-70-20:2015-02

This standard gives details of an accelerated screening test method and acceptance criteria to determine the suitability of silver-plated wire and cable materials for use on spacecraft and associated equipment. The test method, which also determines the suitability of the associated fabrication processes, is based on the work of Anthony and Brown (1965). Anthony and Brown established that "red plague" originates at breaks in the silver-plating of copper wire strands in the presence of moisture and oxygen. The environmental test system artificially promotes "red plague" corrosion under controlled laboratory conditions as a result of galvanic corrosion of the copper conductor core. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00. This document (EN 16602-70-20:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document has been developed to cover specifically space systems and has therefore precedence over any European Standard covering the same scope but with a wider domain of applicability (for example: aerospace). The responsible German committee is Working Group NA 131-10-01 AA "Interoperabilität von Informations-, Kommunikations- und Navigationssystemen" ("Interoperability of information, communication and navigation systems") at DIN Standards Committee Aerospace (NL).
