Certificates of Compliance are permitted in lieu of Certified Material Test Reports for the following cases: 1) For valve or valve components acquired from stock for which material test reports are not obtainable. 2) When the marking of materials covered in this practice are missing or are removed during fabrication operations, provided certification of the unmarked material is acceptable to the Inspector; to the governing standard, specification, or code; and provided the Manufacturer can furnish evidence that the certification is accurate. The use of a certificate of compliance shall be permitted in this case, only if accompanied by material test reports whose number shall be listed in the certificate. 6.4 When the examinations, tests, or operations referred to in the following subparagraphs are included in the fabrication sequence, the Manufacturer shall retain the following records: 1) Written procedures and personnel qualification certificates for all applied nondestructive testing, such as radiographic, ultrasonic, magnetic particle, and liquid penetrant. 2) Examination reports for the results of required magnetic particle, liquid penetrant, radiographic, ultrasonic, or other methods of examination; and certified results of all impact tests. 3) Charts or other records of required hydrostatic, pneumatic and other tests. Test logs shall include the date, testing fluid, duration of the test, temperature of the test fluid, test pressure, a description of the tested valve, a traceable identifying number such as a shop order number, and the signature of the manufacturer’s shop inspector witnessing the test. 4) Pyrometer charts or other detailed records of heat treatment performed such as postweld, normalizing, and heating for forming. 5) A detailed description of all repair, including a sketch, photo, or drawing indicating the location and size of the repaired area. 6) Other material records when specified by the applicable code or the material specification or as required by the purchaser. 6.5 (*)When welding is included in the fabrication sequence of the manufacturer or any of his subvendors, records and forms shall be handled as follows: 1) For commodity valves, Welding Procedure Specifications (WPS) and the Procedure Qualification Records (PQR) shall be made available to the Owner’s Engineer. For non- commodity, special order valve, WPS and PQR shall be submitted to and approved by the Owner’s Engineer before fabrication can start. 2) Welder/welding operator qualification test results shall be retained by the Manufacturer for five years. 3) Radiographic film is to be retained in the shop for review by the Inspector. 6.6 Engineering data requirements shall conform to the following: 1) Certified dimensional drawings of valves shall be submitted to the Purchaser for review and approval, when catalog dimensional data are not available. 2) Certified dimensional drawings shall include all valve components complete with the respective material specification and description.
