ISO 26721 is officially titled:
“Vacuum technology — Test method for gas desorption characteristics of materials and components in vacuum”
This standard specifies a test method to determine the gas desorption rate from materials and components when exposed to vacuum. It provides:
The standard ensures that vacuum components used in sensitive environments do not release gases that can contaminate systems or interfere with experiments and production.
Outgassing or desorption of gas molecules from materials under vacuum can lead to:
ISO 26721 provides a unified method to quantify and compare the desorption behavior of materials, helping manufacturers and users select the most suitable and clean vacuum-compatible components.
Implementing ISO 26721 offers major benefits:
Here’s how ISO 26721 benefits your organization:
Demonstrate the cleanliness and suitability of your components for high-vacuum systems.
Comply with strict vacuum quality regulations in sectors like aerospace, semiconductor, and R&D.
Minimize outgassing-related failures that lead to downtime or rejected batches.
Use ISO 26721-aligned methods as part of laboratory quality assurance and test method validation.
Market your components or systems as ISO-tested and cleanroom-compatible.
Reduce system cleaning, vacuum pump degradation, and downtime from contamination issues.
