1 Scope This standard specifies the thermal efficiency and test methods of coal fired, oil fired and electrically heated boilers for daily life. This standard is applicable to the following fixed boilers for daily life with water being medium and fired by coal, oil and gas or heated with electric energy. a) Steam boiler with a rated working pressure of at most 1.0MPa and a rated evaporation less than 1t/h; b) Pressure-bearing hot-water boiler with a rated thermal power less than 0.7MW; c) Normal pressure hot water boiler (hereinafter referred to as normal pressure boiler) and vacuum phase-change hot water boiler (hereinafter referred to as vacuum boiler). This standard is not applicable to heat recovery boiler and the boiler not adopting water as medium. 2 Normative References The following documents are essential or necessary for the application of this document.
