To e
34、valuate and compare different appliances it is therefore necessary to refer to a single stipulated value, hereinafter called the standard thermal output. The standard thermal output is a defined value taken from the characteristic equation. The pre-requisites of the standard thermal output, as defin
35、ed by this European Standard, are the following: to be representative of the actual output of the appliance; to be reproducible within the tolerances defined by this European Standard, taking into account the state of measuring techniques; to be representative of the thermal output, obtainable under
36、 the same test conditions, of any identical sample taken out of the current production (within the tolerances defined by this European Standard taking into account the state of measuring techniques and methods of manufacture). This European Standard for radiators and convectors consists of the follo
37、wing Parts: Part 1: Technical specifications and requirements; Part 2: Test methods and rating; Part 3: Evaluation of conformity. 1 Scope This European Standard defines procedures for determining the standard thermal output of heating appliances fed with water or steam at temperatures below 120 C, s
38、upplied by a remote heat 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 in
39、itial test. This European Standard also defines the additional common data that the manufacturer shall provide to the trade in order to ensure the correct application of the products. This European Standard does not apply to independent heating appliances. 2 Normative references This European Standa
40、rd incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to t
41、his European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

EN 442-2:1996 6 BSI 19 November 2003 3 Definitions For the purposes of this standard, the following definitions apply: 3.1 heating appliance a device having the purpose of transferring heat in order to provide specific temperature conditions inside buildings. 3.2 i
44、ndependent heating appliance a self-contained heating appliance which does not need to be connected to a remote heat source (e.g. a boiler) as it contains its own heat source (e.g. gas fired appliances, electric appliances, heat pump appliances). 3.3 radiator a heating appliance which emits heat by
45、free convection and radiation. Radiators can be produced with different materials (e.g. steel, aluminium, cast-iron) and with different designs (e.g. plate type, column type, tube type). 3.4 sectional heating appliances (mainly applied to radiators) a heating appliance manufactured in sections of id
46、entical design and traded in this form which can be joined together into modular assemblies so that the desired output can be obtained. 3.5 free convection heating appliance a heating appliance which does not contain a fan or similar device to activate the air flow over heat emitter (see 3.6 and 3.7
47、). 3.6 forced convection heating appliance a heating appliance which requires the action of a fan or similar device to blow or draw air over the heat emitter. 3.7 convector a heating appliance which emits heat almost entirely by free convection. A convector comprising at least a heat emitter and a c
48、asing which provides an unheated convective chimney of defined height. 3.8 fan-assisted radiator or convector a radiator or a convector equipped with a fan to increase the convective heat emission, characterized by two thermal outputs, one with the fan off and the other with the fan in operation. 3.
49、9 height of the unheated convective chimney the vertical distance between the lowest edge of the convector and the bottom of the air outlet section It applies to convectors only, being a main factor influencing their thermal output. 3.10 wet heating surface; primary heating surface the portion of the heat emitting surface which is always in contact with the primary fluid (water or steam). 3.11 dry heat
