What is BS EN 377 - Lubricants to be used in gas appliances about?
BS EN 377 specifies requirements and methods of test for lubricants to be used in gas appliances of all categories including auxiliary equipment mounted or intended to be mounted on such appliances and which may be in contact with combustible gases, except those designed for use in industrial processes.
Who is BS EN 377 - Lubricants to be used in gas appliances for?
BS EN 377 on lubricants to be used in gas appliances is useful for:
- Producers and suppliers of lubricants
- Oil and lubricant companies
- Testing laboratories
- Gas appliances manufacturers
- Quality control authorities
Why should you use BS EN 377 - Lubricants to be used in gas appliances?
A good lubricant generally shows characters like high boiling point, good thermal stability, high viscosity index etc. Therefore, to ensure the suitability of lubricants, determining it’s chemical and physical characteristics is essential.
BS EN 377 specifies the essential physical and chemical characteristics of lubricants to be used in gas and associated controls appliances using combustible gases except those designed for use in industrial processes.
Note: Judgement on the suitability of the use of these lubricants for any given equipment is not the object of the BS EN 377. This has to be verified by functional tests laid down in the appropriate appliance or control standards.
Notwithstanding the limits of operating temperature covered by this standard, it may be necessary to check any specific operating temperature by functional testing and compatibility trials. The lubricants covered by BS EN 377 are compatible with copper and copper alloys. Compatibility with other metals — e.g. aluminium and aluminium alloys (which might be corroded by alkaline soaps) — has to be confirmed by long term functional tests at the maximum working temperature.
BS EN 377 contains an guidance on the preparation of a standard reference elastomer used for testing the compatibility with elastomers.
