Bibliography

This European Standard specifies the requirements and test methods for the construction, safety, classification and marking of non-domestic gas fired overhead radiant tube heaters incorporating a single burner system under the control of an automatic burner control system, referred to in the body of the text as 'appliances'.This standard is applicable to Type A2, A3, B12, B13, B22, B23, B42, B43, B52, B53, C12, C13, C32 and C33 appliances intended for use in other than domestic dwellings, in which the supply of combustion air and/or the evacuation of the products of combustion is achieved by mechanical means located upstream of the draught diverter, if provided.This standard is not applicable to:a)appliances designed for use in domestic dwelling;b)outdoor appliances;c)appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference test gas);d)appliances having fully pre-mixed gas and air burners in which:1)either the gas and all the combustion air are brought together just before the level of the combustion zone; or2)the pre-mixing of the gas and all combustion air is carried out in a part of the burner upstream of the combustion zone;e)appliances that are designed for continuous condensation within the flue system under normal operating conditions;f)appliances having combustion products evacuation ducts that are non-metallic.This standard is applicable to appliances which are intended to be type tested. It also includes requirements concerning the evaluation of conformity, including factory production control, but these requirements only apply to POCEDs and their associated terminals.NOTERequirements for appliances which are not intended to be type tested would need to be subject to further consideration.Requirements concerning the rational use of energy have not been included in this European Standard.
