What is BS EN 16602-70-71- Materials, processes, and their data selection for space product assurance about?  
BS EN 16602-70-71 has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g.: aerospace).
BS EN 16602-70-71 specifies the requirements applicable to materials, processes, and their data selection to satisfy the mission performance requirements.
BS EN 16602-70-71 covers the following:
- Selection criteria and rules
- Utilization criteria and rules
BS EN 16602-70-71 may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00. 
Who is BS EN 16602-70-71- Materials, processes, and their data selection for space product assurance for? 
BS EN 16602-70-71 on materials, processes and their data selection for space product assurance is useful for: 
- Aeronautical engineers 
- Spacecraft manufacturers 
- Astronauts 
- Testing agencies involved in the inspection of aerospace products  
Why should you use BS EN 16602-70-71- Materials, processes, and their data selection for space product assurance?  
Guidelines provided in BS EN 16602-70-71 help with materials, processes, and their data selection for space product assurance.
The provisions of BS EN 16602-70-71 apply to all actors involved at all levels in the production of space systems. These can include manned and unmanned spacecraft, launchers, satellites, payloads, experiments, electrical ground support equipment, mechanical ground support equipment, and their corresponding organizations.
BS EN 16602-70-71 specifies the minimum requirements and the procedures relevant to obtaining approval for the use of materials, processes, and their data selection in the fabrication of space systems and associated equipment.
