Sealing materials for metallic threaded joints in contact with 1st, 2nd and 3rd family gases and hot water - Unsintered PTFE tapes1 Scope This European Standard specifies requirements and test methods for unsintered polytetrafluorethylene (PTFE) tapes (hereafter referred to as PTFE tapes) which are suitable for sealing threaded metallic joints as specified in ISO 71. The PTFE tapes are typically for use in installations for 1st family gases (town gas), 2nd family gases (natural gas) and 3rd family gases (liquefied petroleum gases (LPG)) up to 5 bar and up to 7 bar for hot water
