Radiators and convectors are components for installation in a permanent manner in construction works. This European Standard covers radiators and convectors fed with water or steam at temperatures below 120 C, supplied by a remote heat source. This European Standard does not apply to independent heating appliances. 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. 2 Normative references This European Standard 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 this 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, Radiators and convectors Part 2: Testing and rating methods.

EN 442-1:1995 4© BSI 26 February 2004 4 Pretreatment and paint The pretreatment and paint processes used, shall provide a protective coating to all external surfaces in contact with the air which shall: give protection against corrosion in normal storage and installation conditions (as demonstrated by absence of surface corrosion after 100 h humidity test according to a technical specification valid in the country of destination; be resistant to minor impact damage as demonstrated by a 2 mm cross-hatch test with a single blade cutting tool manually operated according to ISO 2409:1992. The test result shall be within the first three steps (0-1-2) of Table 1 of ISO 2409:1992. The paint shall not contain any chemical substances the use of which is not allowed in building products2). The compliance with the relevant Directive shall be stated by the manufacturer of the radiator/convector. 5 Dimensional tolerances and pressure tightness The dimensional tolerances shall not be greater than those in the manufacturers drawings. In any case they shall not be greater than those given in Table 2 of EN 442-2:1996. 5.1 Material specification and wall thickness of wet heating surface The following values for material thickness for steel radiators, tubular radiators and finned tube convectors shall be measured before pressing or fabrication. Wall thickness of cast-iron, cast aluminium or extruded aluminium radiators refers to the nominal drawing dimensions minus all admissible tolerances. 5.1.1 Steel radiators (radiators manufactured from steel sheet or coil) The wet heating surface materials of steel radiators shall be low carbon steel sheet, which is free from scale or rust and which complies with EN 10130 grade Fe PO1 and with EN 10131. The thickness of the steel used for wet surfaces shall not be less than 1,11 mm. The compliance with this requirement shall be verified by measuring. 5.1.2 Cast-iron radiators Cast-iron radiators shall be manufactured from grey cast-iron complying with ISO 185. The wet wall thickness shall not be less than 2,5 mm. The minimum wall thickness shall be ensured by periodic controls of the casting equipment and daily random production checks. Compliance with this requirement shall be verified by measurement. 5.1.3 Cast aluminium radiators Cast aluminium alloy radiators shall be manufactured from alloy AlSi9Cu3): (N. 46 000 and N. 46 001). The wet wall thickness shall not be less than 1,5 mm. The minimum wall thickness shall be ensured by periodic controls of the casting equipment and daily random production checks. Compliance with this requirement shall be verified by measurement. 2) Also in relation to Directive 76/769/EEC, as amended. 3)prEN 1706 is under preparation by CEN/TC 132/WG1. See Table 1. EN 442-1:1995 © BSI 26 February 2004 5 5.1.4 Extruded aluminium radiators Extruded aluminium alloy radiators shall be manufactured from wrought aluminium alloy EN AW-6060 of the EN 573-3 corresponding to the alloy AlMgSi. The wet wall thickness shall not be less than 1,1 mm. The minimum wall thickness shall be ensured by periodic controls of the extruder and daily random production checks. Compliance with this requirement shall be verified by measurement. 5.1.5 Tubular radiators The material specification and gauge of tubes used in manufacture will be dependent on the tube size and profile and on the process of assembly. They shall nevertheless be sufficient to satisfy the general minimum requirements of 5.2 and 5.3 and the wall thickness of the tube used shall not be less than 0,8 mm. Compliance with this requirement shall be verified by measurement. 5.1.6 Finned tube convectors The wall thickness of the tube shall not be less than 0,8 mm. Compliance with this requirement shall be verified by measurement. 5.1.7 Reaction to fire The materials from which radiators and convectors are made (steel, cast iron and aluminium) are considered to be reaction to fire Class A1 without the need for testing4), provided that any organic part of the paint or coating is less than 1 % by mass or volume. If any organic part of the paint or coating exceeds 1 % by mass or volume (whichever is the more onerous), the material shall be tested and classified according to EN 13501-1 and the resulting class stated. The percentage of organic part of the paint or coating is referred to the actual operating conditions of the radiator and convector (i.e. to the ma
