Industrial valves. Testing of metallic valves - Tests, test procedures and acceptance criteria. Supplementary requirements best-seller BS EN 843-5 specifies a1 Scope This European Standard specifies supplementary requirements for tests, test procedures and acceptance criteria of 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, this European
