Overview
EN 751-1:1996 is a CEN European Standard that specifies requirements and test methods for anaerobic jointing compounds used as sealing materials for metallic threaded joints (e.g., threads per ISO 7-1). The standard covers anaerobic sealants intended for use in contact with 1st family gases (town gas), 2nd family gases (natural gas), 3rd family gases (LPG, excluding LPG in liquid form) and hot water in heating systems. EN 751-1 is intended to ensure safe, reliable sealing performance of anaerobic compounds in gas and hot-water pipework.
Key Topics
- Scope and application: Defines the intended uses for anaerobic jointing compounds on metallic threaded joints in gas supply and heating systems.
- Performance requirements: Sets out the types of requirements the jointing compounds must meet to be considered suitable (sealing integrity, compatibility with thread dimensions such as ISO 7-1, and suitability for the specified gas families and hot water).
- Test methods: Specifies test procedures to evaluate product performance and compliance - for example, tests addressing leak-tightness and interaction with gas and hot-water environments (standard describes required test methods rather than proprietary lab techniques).
- Marking and documentation: Requirements for product identification, manufacturer information and declaration of suitability for use with specified gas families and hot water.
- Safety and conformity: Guidance for manufacturers and conformity assessment to support safe installation and regulatory compliance.
