Characterizing gas separation membranes is a critical step in advancing membrane technology for industrial applications—ranging from carbon capture to hydrogen purification and natural gas upgrading. However, the membrane field has long suffered from inconsistent testing methods, making it difficult to compare data between laboratories or across publications.
To address this, the European Committee for Standardization (CEN and CENELEC) has now published a new set of technical guidelines titled:
“Guidelines on characterization and testing of membranes for gas separation applications.”
These guidelines aim to bring much-needed alignment and clarity to the field by defining a unified framework for:
- Measuring gas permeability in dense films
- Standardizing test conditions and procedures
- Reporting performance metrics in a comparable format
By following these guidelines, researchers, developers, and technology users across Europe and beyond can ensure that gas permeation data are more reproducible, interpretable, and useful for benchmarking and material selection.
We’re proud to share that EMI Twente BV contributed to this effort. Our colleagues Oguz Karvan and Herman Teunis were involved in drafting and reviewing the technical content, drawing from their extensive practical experience in gas permeation testing and membrane development.
These new standards represent a significant step forward for the membrane community—and will help accelerate the development of next-generation gas separation technologies by enabling better collaboration, evaluation, and innovation. You can access the guidelines here:
