1 Scope This International Standard is the general standard on generation by combustion sub-systems (boilers) for oil, gas, coal and biomass burning. It specifies the

• — required inputs,
• — calculation method, and
• — resulting outputs

for space heating generation by combustion sub-systems (boilers) including control. This International Standard is also intended for the case of generation for both domestic hot water production and space heating.
