What is BS EN 3155-001 - Electrical contacts used in elements of connection about?  
BS EN 3155-001 specifies:
- The electrical, mechanical, environmental, and dimensional characteristics of electrical contacts used in elements of connection, including coaxial, triaxial, and quadrax contacts
- The conditions for qualification, acceptance testing, and quality assurance
- The test programs and groups
BS EN 3155-001 is applicable to removable crimp contacts, wrap contacts, solder contacts used in connectors or in other elements of electrical connection. In case of conflict or missing information between the EN 3155-001 and the product standards, the product standard shall govern.
Who is BS EN 3155-001 - Electrical contacts used in elements of connection for? 
BS EN 3155-001 on electrical contacts used in elements of connection is useful for: 
- Aerospace avionic electrical and fibre optic technology 
- Design engineers for electrical contacts 
- Aerospace electric equipment manufacturers 
- Quality control personnel for electrical contacts 
- Aerospace and defence industries
