Overview
SIST EN 4840-101:2018 is a European Standard developed by CEN for aerospace applications, specifically addressing heat shrinkable moulded shapes made from semi-rigid polyolefin with limited fire hazard properties. These heat-shrinkable boots are designed for use in aircraft electrical systems and are suitable for operating temperatures ranging from −30 °C to 105 °C. The standard outlines the technical requirements, testing methods, and quality criteria to ensure reliable performance in aerospace electrical insulation and protection.
This standard contributes to the safety and functionality of electrical wiring in aircraft by specifying materials that meet stringent fire hazard limits and temperature resistance, thereby maintaining system integrity in demanding aviation environments.
Key Topics
