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 Ethylene tetrafluoroethylene (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 are utilized, the voltage rating will be limited to 600Vrms. During a continuous operation, the stabilized conductor temperature will be limited to 150C.
The construction of the wire is determined by the wire and cable type, class, and gauge size. With 65 types and seven classes, the specifications cover sizes 24 AWG through 4/0 AWG. When completed, the products will have a jacket color of white unless otherwise specified.
