This SAE Aerospace Information Report provides additional information and background in regard to the dimensional life of a heat-shrinkable sleeve. The term dimensional life is newly introduced in AS23053 to relate to the dimensional stability instead of the material stability often associated or referred to as the “shelf life.” When the material exceeds such shelf life, it becomes harmful or non-functional.
This ARP specifies the recommended methods of handling silver coated conductors and shield, by the conductor fabricator, wireinsulator, distributors, harness or assembly houses, and OEM’s. Red Plague mitigation depends upon each link in the chain of supply handling the wire and cable properly.
This SAE Aerospace Recommended Practice (ARP) shall be limited to information about corrosion caused by fluoride offgassing of fluoropolymer-based wire insulation. It reviews published reports of corrosion caused by this phenomenon, describes scenarios where this may be a concern, mitigation options, and references a test method which can be used to evaluate wire insulations where needed.
