English version of certification programme ZP 5101 “Compatibility and permeation properties of elastomer materials for seals and diaphragms in gas appliances and equipment against hydrogen for a content of up to 100 vol. % H2”

DVGW CERT GmbH publishes the English version of the certification programme programme ZP 5101 “Compatibility and permeation properties of elastomer materials for seals and diaphragms in gas appliances and equipment against hydrogen for a content of up to 100 vol. % H2”.

It describes the requirements, motivation, and tests to characterize elastomer materials for seals and diaphragms in gas equipment and systems for the use with up to 100 % by volume hydrogen (H₂) with respect to permeation of H₂. The permeation properties can be used for material selection and for the design of components in an application. The objective of this certification programme are material tests on elastomer materials with DIN-DVGW certification according to DIN EN 549 or DIN EN 682.
At the same time, the German version has been editorially revised.
