What is BS EN 4531-002 - Specification of performance and contact arrangements of flush contacts about?  
BS EN 4531-002 defines the performance and contact arrangements of circular optical connectors, coupled by a triple start threaded ring.
BS EN 4531-002 covers the terms and definitions, required characteristics, description, codification of models, polarization, filler plugs, rear accessories, tooling, cleaning instructions, and technical specifications of circular optical connectors, coupled by a triple start threaded ring. 
EN 4531-002 has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN).
Who is BS EN 4531-002 - Specification of performance and contact arrangements of flush contacts for? 
BS EN 4531-002 on the specification of performance and contact arrangements of flush contacts is useful for: 
- Spacecraft and space product manufacturers 
- Industries such as aerospace and defence
- Testing agencies involved in the inspection of spacecraft and aerospace products 
- Quality control personnel for spacecraft products 
Why should you use BS EN 4531-002 - Specification of performance and contact arrangements of flush contacts?  
The guidelines given in BS EN 4531-002 help to select the right connector as connectors improve the production process. If an electronic component fails, the failed component can be replaced when an electrical connector is installed.
The guidelines provided in BS EN 4531-002 help the design engineer with the use of electrical connectors to have greater flexibility while designing and integrating new products and composing systems with components as well.
BS EN 4531-002 is structured such that the necessary level of quality is achieved, consistently maintained, and the high reliability of the product is assured. By adopting BS EN 4531-002, manufacturers can demonstrate the reliability of their products and build trust in their use throughout the aerospace supply chain.
