Overview
EN 377:1993 (CEN) is a European standard that specifies requirements and methods of test for lubricants intended for use in gas appliances and their associated controls that handle combustible gases, excluding lubricants designed for industrial-process equipment. The standard covers lubricants used in appliances of all categories, including auxiliary equipment and mounted control devices that may come into contact with gas.
Key topics and requirements
The standard focuses on practical safety and compatibility aspects of lubricants for gas-service applications. Core topics include:
- Scope and definitions clarifying which appliances and controls are covered and the exclusion for industrial-process lubricants.
- Performance requirements that lubricants must meet to be suitable for use in gas appliances (chemical and functional compatibility with gas system components).
- Methods of test to verify that a lubricant meets required performance characteristics (procedures for evaluating stability, contamination risk and behavior in contact with combustible gases and control parts).
- Materials interaction considerations for seals, valves, regulators and other parts that may contact lubricant.
- Documentation and marking expectations to ensure traceability and correct application.
The standard does not prescribe specific product formulations; rather it defines test approaches and acceptance criteria relevant to safe operation of gas appliances.
Applications
EN 377:1993 is used to ensure that lubricants:
- Do not degrade gas-control performance (valves, regulators, actuators).
- Are chemically compatible with combustible gases and appliance materials.
- Meet reliability and safety expectations for domestic, commercial and some non-industrial gas appliances.
Typical application areas include:
- Domestic and commercial gas cookers, heaters and boilers
- Mounted regulators, valves, actuators and control devices on gas appliances
- Auxiliary equipment that may contact combustible gaseous fuels
Who uses this standard
- Appliance manufacturers specifying or approving lubricants for assembly and maintenance
- Lubricant producers developing or certifying products for gas-service applications
- Component suppliers (valves, regulators, seals) validating material compatibility
- Testing laboratories performing conformity testing to CEN requirements
- Certification bodies and safety authorities assessing product compliance
Related standards
EN 377 is part of the wider body of CEN/ISO standards addressing gas appliances, safety, and lubricants. Users should consult other applicable CEN/ISO standards and national regulations for appliance testing, gas safety and lubricant classification.
