What is BS EN 12266-2 - Testing of metallic valves about?

BS EN 12266-2 specifies supplementary requirements for tests, test procedures, and acceptance criteria for industrial valves made of metallic materials. The specified tests may be used as type tests, production tests, or acceptance tests. The application of these tests is specified in the appropriate product or performance standards.

When specified as a normative reference in a valve product or performance standard, BS EN 12266-2 should be considered in conjunction with the given specific requirements of the valve product or performance standard. Where requirements in a product or performance standard differ from those given in BS EN 12266-2, the requirements of the product or performance standard apply.

Note: For testing of industrial valves of thermoplastic materials, ISO 9393-1 and ISO 9393-2 apply.

Who is BS EN 12266-2 - Testing of metallic valves for?

BS EN 12266-2 on testing of metallic valves is useful for:

Type testing
Acceptance (approval)
Industrial

Acceptance specification
Approval testing

Why should you use BS EN 12266-2 - Testing of metallic valves?

The purpose of BS EN 12266-2 is to establish certain basic requirements for supplementary production pressure testing of industrial valves in order to ensure uniform tests and test procedures. Tests and procedures given in BS EN 12266-2 may be used for production tests and, where applicable, for type tests and acceptance tests.

Special requirements, which are specific to one product or one performance standard only, are not included in BS EN 12266-2. Details should be included in the appropriate standard. Valve testing is a maintenance procedure that assesses the state or health of a working valve. Valve testing is commonly performed to address concerns such as mechanical friction, flashing, cavitation, blocked flow, erosion, and noise, to name a few.
