Under these conditions it is assumed that correct function is preserved. For the visual inspection and the non-destructive tests, all pressure retaining parts shall have a surface finish which makes it possible to conduct the tests in accordance with table 1. [] When fire test certification is required it shall be specified by the purchaser. Certification shall be in accordance with prEN ISO 104971996 or other standard by agreement. The valve shall be asbestos free. [] If the subcontractors are not certified in accordance with EN ISO 9000 series, EN ISO 9001, EN ISO 9002, EN ISO 9003, as appropriate, the purchasers can require to be ined about the change of subcontractors for main parts of a valve e.g. castings, forgings for valves.
