Over deze norm
NEN-EN 442-2 defines procedures for determining the standard thermal outputs and other characteristics of radiators and convectors installed in a permanent manner in construction works, fed with water or steam at temperatures below 120 °C, supplied by a remote energy source. This European Standard specifies the laboratory arrangements and testing methods to be adopted, the admissible tolerances, the criteria for selecting the samples to be tested and for verifying the conformity of the current production with the samples tested at the initial test. This European Standard also defines the additional common data that the manufacturer shall provide with the product in order to ensure the correct application of the products. This European Standard does not apply to fan assisted radiators, fan assisted convectors and trench convectors and to independent heating appliances.
