Defines requirements and methods of test for anaerobic jointing compounds for sealing threaded metallic joints eg those defined in ISO 7-1. Intended for use in contact with 1st to 3rd family gases and hot water of heating systems.

This European Standard specifies requirements and test methods for anaerobic jointing compounds (hereafter referred to as `jointing compounds\') suitable for sealing threaded metallic joints such as those specified in ISO 7-1. These jointing compounds are for use in contact with 1st family gases (town gas), 2nd family gases (natural gas) and 3rd family gases (liquefied petroleum gases (LPG) not including LPG in the liquid form) and hot water of heating systems according to table 1.
