What is BS EN 3475-418 - Thermal endurance for conductors about ?  

BS EN 3475-418 is a European Standard that specifies a test method to value the thermal endurance of bi-metal conductors, by the valuation of the influence of metallic migration on the electrical resistance per unit length. 

It shall be used together with EN 3475-100. 

EN 3475-100 covers terms and definitions, symbols and abbreviations, test conditions, and list of test methods for measuring thermal endurance of conductors. 

Who is BS EN 3475-418 - Thermal endurance for conductors for ? 

BS EN 3475-418 on thermal endurance for conductors is applicable for: 

• Manufacturers of aerospace electrical cables 
• Quality control personnel for aircrafts 
• Aircraft manufacturers 
• Aerospace avionic electrical and fibre optic technology 
• Spacecraft and space products manufacturers 
• Aerospace and defence industries  
• Quality control personnel of electrical cables 

Why should you use BS EN 3475-418 - Thermal endurance for conductors ?

Thermal endurance is the relationship between temperature and the time spent at that temperature required to produce such degradation of electrical insulation that it fails under specified conditions of stress, electric or mechanical, in service or under test. 

BS EN 3475-418 provides you with the guidelines on preparing test specimens and testing procedures of wet arc resistance for preventing damage. 

BS EN 3475-418 covers all the quality control requirements for electrical cables. It creates a standardized approach for manufacturers of electrical cables that they need to adhere to if they supply their electrical cables to the aerospace and defence industries. 

By adopting BS EN 3475-418, manufacturers can demonstrate the reliability of their electrical cables and build trust in their use throughout the aerospace supply chain.
