SAE AS81582C covers environment-resisting, quick disconnect, EMI/RFI shielded and non-shielded umbilical, electric connectors and adapter assemblies with removable crimp or nonremovable solder-type contacts and accessories. Connectors are rated for operation from -55 C (-67 F) to 200 C (392 F). Adapter assemblies are rated for operation from -55 C (-67 F) to 125 C (257 F). The upper temperature is the maximum internal hot spot temperature resulting from any combination of electrical load and ambient temperature.
