This Standard gives details of an accelerated screening test method and acceptance criteria to determine the suitability of silver\u00adplated 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). They established that \u201cred\u00adplague\u201d originates at breaks in the silver\u00adplating of copper wire strands in the presence of moisture and oxygen. The environmental test system artificially promotes \u201c red\u00adplague\u201d 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.<\/p>\n
