What is BS EN 419-Gas-fired overhead luminous radiant heaters about?
BS EN 419 discusses gas-fired overhead luminous radiant heaters. BS EN 419 specifies the requirements and test methods for the construction, safety, rational use of energy, classification, and marking of non-domestic gas-fired overhead luminous radiant heaters for environmental comfort, referred to in the body of the text as “appliances.
BS EN 419 is applicable to Type A1 and Type A3 appliances only intended for use other than residential dwellings:
- Low gas pressure appliances operating at pressures up to and including 50 mbar
- Medium gas pressure appliances operating at pressures above 50 mbar and up to 2 bar
Note: BS EN 419 is not applicable to:
- Appliances designed for use in domestic dwellings
- Outdoor appliances
- Appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference gas)
Who is BS EN 419-Gas-fired overhead luminous radiant heaters for?
BS EN 419 on gas-fired overhead luminous radiant heaters is useful for:
- Gas-fired heater manufacturers
- Quality control personnel
Why should you use BS EN 419-Gas-fired overhead luminous radiant heaters?
Gas-fired high-intensity heaters are direct-fired and pass a gas-air mixture through a porous matrix refractory material which ignites evenly across the surface. BS EN 419 provides you with the necessary guidance for the classification of appliances which includes classification according to gases and categories, and classification according to the mode of the evacuation of the combustion products.
BS EN 419 guides you with constructional requirements and operational requirements. BS EN 419 guides you with energy efficiency which includes the general principle of measurement and calculation of radiant factor. BS EN 419 also guides you with risk assessments which include marking, instructions, marking of the appliance, and the packaging and presentation. BS EN 419 helps you to manufacture high-quality gas-fired overhead luminous radiant heaters.
What’s changed since the last update?
BS EN 419:2019 supersedes BS EN 419‑1:2009 and BS EN 419‑2:2006, which are withdrawn. BS EN 419:2019 includes some technical changes with respect to BS EN 419‑1:2009 and BS EN 419‑2:2006. These include:
- Incorporation recent state of the art of luminous heaters
- Incorporation of medium gas pressure appliances for industrial use
- Unique and more detailed description of method to determine radiant factor
- Incorporating terms and calculation scheme of Ecodesign Regulation (EU) No. 2015/1188
