BMS13-48 Specification

Approved by Boeing, the BMS13-48 specification establishes the requirements for insulated wire and cable with tin-coated, nickel-coated, and silver-coated copper conductors, nickel-coated and silver-coated high strength copper alloy conductors and a primary insulation of cross-linked Ethylenetetrafluoroethylene (ETFE). Intended for "General Purpose" use in both pressurized and unpressurized areas of aircraft, this product's application can withstand exposure to temperatures from -65 C to +150 C and various corrosive fluids. When operating with circuits where this wire and cable is utilized the voltage rating will be limited to 600Vrms, and during a continuous operation the stabilized conductor temperature will be limited to 150C.
