BS EN 4612‑004 is an international standard on tin-plated copper cables with jackets and screens.
BS EN 4612‑004 specifies the characteristics of UV laser printable jacket, tin-plated copper conductor, electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene copolymer (XLETFE) family for use in the onboard electrical systems of aircraft operating at temperatures between 65 °C and 135 °C, operating at voltages not exceeding 600 V rms and frequencies not exceeding 2000 Hz rms at sea level. This insulation system has been used in aerospace applications using 115 V (phase-to-neutral) 400 Hz ac and 28 Vdc.
Tin-plating on copper cable enhances the life of the cable and protects it from corrosion.
BS EN 4612-004 on tin-plated copper electrical cables (single extruded wall for open applications) for aerospace applications is applicable to:
Tin-plated copper wire is primarily used in wastewater treatment facilities, subway systems, and other contaminated environments susceptible to long-term exposure to excess water. The tin coating on the copper protects the wire from corrosion and premature cable failure.
The tin plating on copper makes it easy to solder. Its conductivity is the same as bare copper and it extends the life of the cable. Hence, BS EN 4612‑004 is essential in getting the detailed specification on tin-plated copper cables.
Also, Crosslinked Ethylene Tetra Fluoro Ethylene copolymer (XLETFE) greatly improves the surface resistance, insulation resistance, fire resistance of the cable, and tensile strength of the whole body of the cable. BS EN 4612-004 specifies the characteristics of tin-plated copper electrical cables (XLETFE) and provides essential best practice guidance on using the electrical systems of aircraft.
As a quality control personnel, you can use BS EN 4612-004 for inspection of surface, fire, humidity, and overload resistance. Thus BS EN 4612-004 can help in ease of production and guarantees the machining accuracy of the cable.
