EN 751-1 Metallic Threaded Connections in Contact with 1st, 2nd and 3rd Family Gases and Hot Water, Part 1: Test Standard for Anaerobic Fasteners

EUROLAB laboratory provides testing and compliance services within the scope of EN 751-1 standard. This European standard specifies requirements and test methods for anaerobic joint compounds suitable for sealing threaded metallic joints, such as those specified in ISO 7-1.

These coupling 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) without LPG in liquid form) and hot water of heating systems.

This European standard specifies requirements and test methods for anaerobic joint compounds for metallic threaded connections. These liquid, gel-like or pasty sealants cure in the cavity of the threaded joint in the absence of oxygen, catalyzed by contact with the metal of the threaded joint.

With the time- and temperature-dependent curing reaction, a polymeric material is formed that fills the tooth cavity and micro-defects and bonds strongly to metal surfaces, thereby sealing and bonding the threaded joint.

Anaerobic joint compounds can be formulated to cure at different strength levels. Therefore, users of such materials should consult the manufacturer's information to ensure that the quality is suitable for the application.
