The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This European Standard applies to the determination of the performances of heating boilers and combi boilers fired by liquid fuels. The requirements for the heating performances are laid down in EN 303 1:2016 and EN 303 2:2016.
This test code includes the requirements and recommendations for carrying out and evaluating the procedure for testing boilers and also the details of the technical conditions under which the tests will be carried out.
The requirements and the performance of testing for the sanitary hot water production of combi boilers are laid down in EN 303 6.

This European Standard is applicable to boilers used for central heating in accordance with prEN 303 1:2016 up to a nominal heat output of 1 000 kW and EN 303 4 up to a nominal heat output of 70 kW with forced draught burners in accordance with EN 267 that are designed for operating with liquid fuels.
The performance requirements of this standard apply to type testing to heating boilers (standard, low temperature and condensing boilers) which are tested on a test rig in accordance with the test code given in EN 304.
This standard applies also to room sealed boilers as defined in EN 15035 regarding efficiency and emissions.
This standard can also be used as the basis for evaluation of boiler-/burner units.
