However, an Assembler may convert original ?nished parts by machining to another ?nished part for a speci?c application under the following conditions: (1) Conversions shall be speci?ed by the Manufacturer. Drawings and/or written instructions 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.
