What is BS EN 15502-1 about?
BS EN 15502-1 discusses gas-fired heating boilers with a focus on general requirements and tests. BS EN 15502-1 specifies the common requirements and test methods, as well as the classification, marking and energy labelling of gas-fired central heating boilers that are fitted with atmospheric burners, fan-assisted atmospheric burners, or fully premixed burners. BS EN 15502-1 applies to boilers of types B and C:
- That use one or more combustible gases of the three gas families and where the temperature of the water does not exceed 105 °C during normal operation.
- Where the maximum operating pressure in the water circuit does not exceed 6 bar and which can give rise to condensation under certain circumstances.
- Which are intended to be installed inside a building or in a partially protected place and which are intended to produce also hot water either by the instantaneous or storage principle as a single unit.
Note 1: BS EN 15502-1 is not intended to cover appliances intended for connection to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance.
Note 2: BS EN 15502-1 does not cover appliances above 1000 kW, appliances designed and constructed to burn gas containing carbon monoxide or other toxic components and appliances having a supplementary heater.
Who is BS EN 15502-1?
BS EN 15502-1 on gas boilers is useful for:
- Gas Boiler Manufacturers
- Furnace Manufacturers
- Product design engineers
- Quality control personnel
Why should you use BS EN 15502-1?
Gas-fired boilers are intended to use gases of various qualities. Their operating limits change with changes in gases. As a designer or manufacturer of gas boilers, you need to take into account such considerations. You also need to take this into account for the marking and labelling of products.
BS EN 15502-1 provides you with specifications and requirements that help in the classification, marking and energy labelling of gas-fired heating boilers. BS EN 15502-1 provides you with tests for understanding the limitations and optimum conditions or settings when used with various gases.
What’s changed since the last update?
BS EN 15502-1:2021 supersedes BS EN 15502-1:2012+A1:2015, which is withdrawn. BS EN 15502-1:2021 includes some technical changes with respect to BS EN 15502-1:2012+A1:2015. These include:
- Technical changes related to eco-design and energy labelling for appliances <= 400 kW
- Deletion of the requirements that can be found in the legislation itself
- Modification of the Annexes ZC and ZD
- Separation between requirements and test methods into different clauses
- Definitions added for Instructions for installation, Instructions for use and servicing, and Technical documentation and consequently applied throughout the document
