Brief description

This certification and testing basis describes the requirements, motivation and tests for qualitatively assessing foaming solutions for leak detection for use with up to 100 % hydrogen (H2) by volume with regard to the foam pattern. The evaluation is carried out on a prepared annular gap at which a corresponding leakage occurs at a constant test pressure. The foam pattern is determined for H2 and N2, optionally it can also be determined for other gases such as methane. The respective foam patterns vary depending on the gas type and leakage rate for the specific application
