This European Standard applies to type CX3 central heating boilers as specified in 4.1, equipped with atomizing oil burners:
- Type C13, type C33, and type C53 boilers, including their combustion air supply and combustion products evacuation ducts and their terminals;
- type C43 boilers including their connection ducts but without the chimney which is erected as a shared duct system and which is part of the building;
- type C63 boilers, including the connecting piece as specified in 3.7, if not integrated into the boiler;
- type C83 boilers, including their connection ducts but without the chimney which is part of the building;
- that have a nominal useful heat output below or equal to 70 kW;
- where the temperature of the water does not exceed 100 °C during normal operation;
- where the maximum water-side operating pressure does not exceed 8 bar.
This European Standard is intended to establish specific requirements and test methods for type C atomizing oil burning central heating boilers with respect to construction, safety, fitness for purpose, rational use of energy, classification and marking.
This European Standard only covers standard tests.
For boilers that produce domestic hot water by a drum or exchanger, integrated or juxtaposed, (by accumulation of instant production), this standard only applies to hot water reheating system components that are not subject to operating conditions applicable to the boiler heating system.
This European Standard covers units consisting of boilers equipped with burners that meet the requirements of EN 267, with the following exceptions:
- maximum NOx and CO emission values, estimated for boilers according to the classes defined in
EN 303-2;
- air factor value, defined by the manufacturer and stated in the boiler’s technical specifications;
- marking and/or burner data plate which may provide information for the boiler data plate;
- installation recommendations for installing the burner on the boiler included

This European Standard specifies the requirements and test methods for the safety and efficiency of oil-fired air heaters using only forced draught oil burners, hereafter referred to as "appliances".
This European Standard applies to stationary and portable appliances. It also applies to appliances intended for outdoor installation. Provision of the heated air may be by means of ducting or may be directly into the heated space.
For the purpose of this standard the heat generation is by the combustion of liquid fuel oils as defined in EN 267 (gas oil with a viscosity at the burner inlet of 1,6 mm2/s (cSt) up to 6 mm2/s (cSt) at 20 °C). Alternatively, if the manufacturer requests, the fuel of kerosene may be used as defined in EN 304:1992. Kerosene with a viscosity at the burner of 1,3 mm2/s (cSt) to 2,9 mm2/s (cSt) at 20 °C) or other suitable liquid fuel oils may also be used.
This standard does not apply to:
- appliances intended for use in a single unit residential dwelling;
- appliances of the condensing type;
- appliances with atmospheric burners without a fan to assist the transportation of combustion air;
- dual purpose air conditioning appliances (heating and cooling);
- appliances where the air is heated by an intermediate fluid;
- appliances fitted with manual or automatic flue dampers;
- appliances having multiple heating units with a single flue;
- appliances fitted with more than one flue outlet.
This European Standard is applicable to appliances which are intended to be type tested.
NOTE   Requirements for appliances which are not type tested would need to be subject to further consideration.
