Bibliography

This standard is included in DIN Handbook 379. Specifies requirements for flame arresters which prevent flame transmission when flammable, vapour gas/air-mixtures are present. Establishes uniform principles for the classification, basic construction and making of flame arresters and test methods to verify the safety requirements.
