Disassembly and either reassembly or adjustments, or both, that affect the safety valve or safety relief valve function shall be considered repairs.
(c) The initial installation, testing, and adjustments of a new safety valve or a safety relief valve on a boiler or pressure vessel shall not be considered a repair if made by the manufacturer or assembler of the valve.
(d) Each valve intended for steam services shall be tested on steam. Each valve intended for air or gas service shall be tested on air or gas. All ASME code section IV "HV" and "V" stamped safety valves and relief valves designed for use on low pressure boilers shall be repaired only by the original manufacturer.
