BS EN 3155-003:2019

What is BS EN 3155‑003 - Female electrical contacts about ?  

BS EN 3155‑003 is an international standard for aerospace series that specifies the test methods and characteristics of female electrical contacts which is useful in producing aerospace products. 

BS EN 3155‑003 specifies the required characteristics, tests, and tools applicable to female electrical contacts 003, type A, crimp, class S used in elements of connection. 

Type A contacts are for general application and class S corresponds to an operating temperature range from − 65 °C to 200 °C. 

Who is BS EN 3155‑003 - Female electrical contacts for ?

BS EN 3155‑003 on female electrical contacts for aerospace is applicable to: 

• Aerospace avionic electrical and fibre optic technology 
• Design engineers for electrical contacts 
• Aerospace electric equipment manufacturers 
• Quality control personnel for electrical contacts 
• Aerospace and defense industries 
• Manufacturers of electrical contacts 

Why should you use BS EN 3155‑003 - Female electrical contacts ? 

Female contact is used for electrical, physical, or data transfer and is generally a receptacle that receives and holds the male contact. 

Female contacts are used for fixed mounting on electronic equipment because female contacts are more resistant to damage or contamination. BS EN 3155-003 helps design engineers in designing electrical contacts as per specifications given in BS EN 3155-003 and enhances the reliability of their product. 

BS EN 3155-003 assists aerospace industries as well as testing agencies in making and testing aerospace products with respect to proper dimensions, surface treatment, and alloy.
