BS EN 3475-701-2017 specifies methods for disbonding and adhesion testing of cable conductor insulation for aircraft, applicable to cable products used in the aerospace sector. The standard evaluates the adhesion performance between cable conductors and insulation layers through disbonding and tensile testing, ensuring that the insulation layer will not be easily peeled or damaged during installation and use, thus ensuring the Reliability and safety of the cable. The test results provide a scientific basis for material selection, production process optimization and product quality control, which helps to improve the service life and performance Stability of aircraft cables. The standard is widely used in the design, production and testing of cables in the aerospace sector.
