Scope
This standard specifies the terms, definitions, parameter series, and model compilation methods for phase-change boilers, as well as the basic requirements for safety and performance in aspects such as design, manufacturing, inspection, acceptance, and safety accessories. This standard applies to industrial boilers that operate through phase-change heat transfer, namely phase-change hot water boilers and phase-change steam boilers with a rated working pressure not exceeding 2.5 MPa, including vacuum phase-change boilers, micro-pressure phase-change boilers, and pressure phase-change boilers, hereinafter referred to as boilers.
