BS ISO 24638:2021

What is ISO 24638 about?  

ISO 24638 discusses standards for flight pressure components and pressure system integration. ISO 24638 specifies the baseline requirements for the design, fabrication, and testing of space flight pressure components.  

ISO 24638 also specifies the requirements for the assembly, installation, test, inspection, operation, and maintenance of the pressure systems in spacecraft and launch vehicles. These requirements, when implemented on a particular space system, ensure a high level of confidence in achieving safe and reliable operation. 

ISO 24638 applies to all pressure components other than pressure vessels and pressurized structures in a pressure system.  

ISO 24638 covers lines, fittings, valves, bellows, hoses, and other appropriate components that are integrated to form a pressure system. 

Note: ISO 24638 does not apply to engine components. 

Who is ISO 24638 for? 

ISO 24638 on pressure components for space systems is applicable to: 

• Regulatory authorities 
• Quality control/testing and compliance personnel for space system 
• Space engineers 
• Manufacturers of flight pressure components 
• Aerospace and defence industries 
• Spacecraft manufacturers 
• Testing agencies involved in aerospace applications 

Why should you use ISO 24638? 

High-quality design, analysis and testing of pressure components for use in space systems are required to ensure a high level of confidence in achieving safe and reliable operation. ISO 24638 establishes all the requirements and methods for the assembly, installation, test, inspection, operation, and maintenance of the pressure systems and pressure components in spacecraft and launch vehicles. 

ISO 24638 provides you with design requirements, material requirements, fabrication and process requirements, contamination control and cleanliness requirements. By implementing ISO 24638 standard requirements, you can ensure the safe and reliable operation of spacecraft and launch vehicles. 

ISO 24638 also covers quality assurance programme requirements through which you can ensure engineering requirements, drawings, material specifications, process specifications, workmanship standards, design review records, failure mode analysis, non-destructive inspection (NDI) and acceptance tests are effectively used, such that the completed flight pressure system meets its specified requirements.

What’s changed since the last update?
