Overview
EN 12279:2000 (CEN) defines the functional requirements for gas pressure regulating installations that form part of service lines in gas supply systems. The standard sets out expectations for the behaviour, safety and performance of pressure regulating equipment installed on the service connection between the distribution network and the consumer. It is focused on functional outcomes rather than prescribing detailed design solutions, enabling manufacturers and operators to meet consistent safety and operational benchmarks across Europe.
Key Topics
- Functional requirements for pressure regulating installations on service lines (performance, reliability, fail-safe behaviour)
- Operational safety expectations for pressure regulation in gas distribution systems
- Compatibility with gas supply infrastructure and service line configurations
- Performance criteria for pressure control and stability under varying inlet/outlet conditions
- Inspection, maintenance and access requirements to ensure long-term safe operation
- Marking, documentation and traceability for installed regulators and associated components
- Applicable classification and scope indicators (relevant ICS codes such as 23.060.40 and 91.140.40)
Note: EN 12279:2000 specifies functional outcomes; it does not mandate specific materials, component drawings or proprietary constructions.
Applications
EN 12279:2000 is used to ensure safe and reliable pressure regulation where the service line connects a gas distribution network to a customer installation. Typical applications include:
- Single and multi-consumer service connections in urban and rural gas networks
- Pressure reduction and regulation assemblies installed at service valves or service meter installations
- Situations requiring documented functional performance and compliance for commissioning and inspection
Implementing the standard helps reduce the risk of overpressure, underpressure and other pressure-related hazards, and supports harmonized practices for installation and verification.
Who should use this standard
- Gas network operators and utilities specifying functional requirements for service-line regulators
- Manufacturers and suppliers of pressure regulators seeking compliance with European functional expectations
- Installation contractors, commissioning engineers and maintenance teams responsible for service-line equipment
- Regulators, inspectors and safety assessors reviewing conformity of gas pressure regulation on service lines
Related Standards
- Other CEN/EN standards on gas distribution, pressure regulation and safety (refer to national and European collections for complementary technical specifications).
