Describes the terminology, test procedures and general requirements for the construction and operation of automatic forced draught oil burners supplied with a fuel having a viscosity at the burner inlet of 1,6 mm[2]/s (cSt) to 6 mm[2]/s (cSt) at 20 degree C or higher, boiling petroleum in accordance with ISO 8217-based first raffinates, and the provision of related control and safety devices.

This International Standard specifies the terminology, test procedures and general requirements for the construction and operation of automatic forced draught oil burners supplied with a fuel having a viscosity at the burner inlet of 1,6mm2/s (cSt) to 6mm2/s (cSt) at 20°C or higher, boiling petroleum in accordance with ISO8217-based first raffinates, and the provision of related control and safety devices. It is applicable to the following: automatic oil burners (hereinafter called “burners”) fitted with a combustion air fan and equipped as described in Clause5, intended for use in appliances of different types and operated with fuel oils; single burners with a single combustion chamber, for which, where such burners are fitted to a single appliance, the requirements of the relevant appliance standard also apply; single-fuel and dual-fuel burners when operating only on oil; the oil function of dual-fuel burners designed to operate simultaneously on gaseous and liquid fuels, which, for the former, the requirements of ISO22967 also apply. It is not applicable to burners used in direct fired processes either with defined combustion chamber applications or where the combustion chamber wall surface temperature is greater than 750°C or the heat-transfer medium temperature is greater than 500°C.
