What is BS EN 4531-001 - Threaded ring coupling about ?
BS EN 4531-001 is a European Standard specifies the general characteristics, the conditions for qualification, acceptance, and quality assurance, as well as the test programs and groups for threaded ring coupling circular fibre optic self-locking connectors, fire-resistant or non-fire-resistant, intended for use in a temperature range from −65 °C to 150 °C (cable dependent) continuous
Who is BS EN 4531-001 - Threaded ring coupling for ?
BS EN 4531-001 on the threaded ring coupling is useful for: 
- Aerospace avionic electrical and fibre optic technology
- Spacecraft and space products manufacturers 
- Aerospace and defence industries  
- Design engineers for aerospace products
- Quality control personnel for spacecraft products 
Why should you use BS EN 4531-001 - Threaded ring coupling ?
The threaded coupling means the coupling has threads at one or both ends.
The guidelines given in BS EN 4531-001 helps 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 4531-001 helps 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 4531-001 is structured such that the necessary level of quality is achieved, consistently maintained, and the high reliability of the product assured. By adopting BS EN 4531-001, manufacturers can demonstrate the reliability of their products and build trust in their use throughout the aerospace supply chain.
