What is BS EN 4612‑007- Jacketed or screened and jacketed about?
BS EN 4612‑007 is the seventh part of the multi-series standard that specifies the characteristics of UV laser printable jacket, silver-plated copper conductor, electrical cables crosslinked ethylene tetra fluoro ethylene co-polymer (XLETFE) family for use in the onboard electrical systems of aircraft operating at temperatures between – 65 °C and 150 °C, operating at voltages not exceeding 600 V 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. Verification of the suitability of cables for use in other electrical systems is the responsibility of the user.
These jacketed cables are suitable for airframe use without additional protection when the jacket is present. When the jacket is stripped back the cores may need additional protection. In case of conflict between BS EN 4612‑007 and other referenced documents, the requirements of this standard shall take precedence.
Who is BS EN 4612‑007- Jacketed or screened and jacketed for?
BS EN 4612-007 on Jacketed or screened and jacketed cables are useful for:
- Aircraft manufacturers
- Aircraft operator
- Servicemen of aircrafts
- Safety regulatory bodies
- Purchasers of cable jackets
Why should you use BS EN 4612‑007- Jacketed or screened and jacketed?
BS EN 4612-007 provides requirements for materials and construction for jacketed cables for use in the onboard electrical systems of aircraft operating at temperatures between – 65 °C and 150 °C, operating at voltages not exceeding 600 V RMS at sea level.
BS EN 4612-007 specifies that the screens and braids should be nickel or silver, or tin-plated copper or copper alloy as specified in the product specification.
BS EN 4612-007 also provides the color coding for the jackets so that the purchaser can know which jacket he should purchase as per the need.
BS EN 4612-007 helps verify the suitability of cables for use in other electrical systems.
