【正文】 ctions used for part conversion shall be obtained from the Manufacturer and shall include a drawing or description of the converted Part before and after machining. (2) The Assembler’ s quality control system, as accepted by a representative from an ASME designated anization, must describe in detail the conversion of original parts, provisions for inspection and acceptance, personnel training, and control of current Manufacturer’ s Drawings and/or written instructions. (3) The Assembler must document each use of a converted part and that the part was used in strict accordance with the instructions of the Manufacturer. (4) The Assembler must demonstrate to the Manufacturer the ability to perform each type of conversion. The Manufacturer shall document all authorizations granted to perform part conversions. The Manufacturer And Assembler shall maintain a ?le of such authorizations. (5) At least annually a review shall be performed by the Manufacturer of an Assembler’ s system and machining capabilities. The Manufacturer shall document the results of these reviews. A copy of this documentation shall be kept on ?le by the Assembler. The review results shall be made available to a representative from an ASME designated anization. UG136(c) (5) In addition to the requirements of UG129, the marking shall include the name of the Manufacturer and the ?nalAssembler. The Code Symbol Stamp shall be that of the ?nal Assembler. NOTE: Within the requirements of UG136(c) and (d): A Manufacturer is de?ned as a person or anization who is pletely responsible for design, material selection, capacity cortication, manufacture of all ponent parts, assembly, testing, sealing, and shipping of pressure relief valves credited under this Division. An Assembler is de?ned as a 6 person or anization who purchases or receives from a Manufacturer or another Assembler the necessary ponent parts or pressure relief valves and assembles, adjusts, tests, seals, and ships pressure relief valves credited under this Division, at a geographical location other than and using facilities other than those used by the Manufacturer. An Assembler may be anizationally independent of a Manufacturer or may be wholly or partly owned by a Manufacturer. UG136(d) Production Testing by Manufacturers and Assemblers UG136(d) (1) each pressure relief valve to which the Code Symbol Stamp is to be applied shall be subjected to the following tests by the Manufacturer or Assembler. A Manufacturer or Assembler shall have a documented program for the application, calibration, and maintenance Of gages and instruments used during these tests. UG136(d)(2) The primary pressure parts of each pressure relief valve exceeding NPS 1 (DN 25) inlet size or 300 psi (2100 MPa) set pressure where the materials used are either cast or welded shall be tested at a pressure Of at least times the design pressure of the parts. These tests shall be conducted after all machining operations on the parts have been pleted. There shall be no visible sign of leakage. UG136(d) (3) the secondary pressure zone of each closed bon pressure relief valve exceeding NPS 1 (DN 25) inlet size when such pressure relief valves are designed for discharge to a closed system shall be tested With air or other gas at a pressure of at least 30 psi (200 kPa). There shall be no visible sign of leakage. UG136(d) (4) each pressure relief valve shall be tested to demonstrate its popping or set pressure. Pressure relief valves marked for steam service or having special internal parts for steam service shall be tested with steam, except that pressure relief valves beyond the capability Of the production steam test facility either because of size or set pressure may be tested on air. Necessary corrections for differentials in popping pressure between steam and air shall be established by the Manufacturer and applied to the popping point on air. Pressure relief valves marked for gas or vapor may be tested
