Certification reference standard

Scope of the programme

This certification program of the NF047 Mark covers the heating appliances. It is divided into four sub-programs:

  • Radiators and convectors.
  • Ceiling-mounted radiant panels.
  • Radiators and convectors assisted with fan.
  • Mixed radiators.

Definitions

This certification concerns the devices to be used with hot water and for some cases with addition of electricity.

Devices which have the purpose of transferring heat under to provide specific temperature condition inside building.

Radiators et convectors

These products are manufactured in accordance with the specifications and requirements of the EN 442 European standard.

Radiators are heating appliances produced in manufacturing unit with different materials (e.g. steel, aluminium, cast-iron), which emits heat by free convection and radiation.

Convector are heating appliances produced in manufacturing unit established with aluminium battery and casing. The heating is emitted almost entirely by free convection.

Ceiling-mounted radiant panels

These devices are manufactured in accordance with the specifications and requirements of the EN 14037 European standard. There are often used in the tertiary sector. The heating is emitted almost entirely by free radiation.

Radiators and convectors assisted with fan

These devices are manufactured in accordance with the specifications and requirements of the EN 442 European standard equipped with fan intended to increase the convection thermal power.

Mixed radiators

These devices are manufactured in accordance with the specifications and requirements of the EN 442 European standard equipped with electrical resistance and/or blower.

Radiator and mixed towel warming radiator without blower 

Comprises a hot water central heating radiator, a resistor and a control system. The immersed resistor is mounted inside the radiator in direct contact with the central heating circuit.

Radiator and mixed towel warming radiator with blower 

Comprises a hot water central heating radiator, an electric blower and a control system. The blower is attached to the radiator and cannot be detached.

Certified characteristics

Radiators and convectors.

  • The thermal output, 
  • The maximum operating pressure.

Ceiling-mounted radiant panels

For the electric part: 

  • The standby power, 
  • The power when in operation. 

Mixed radiators

  • The thermal output, 
  • The maximum operating pressure.
  • the surface temperature of mixed radiators with a resistor, 
  • the air outlet temperature for mixed radiators with a blower, 
  • the output of the resistor and/or of the blower.
