This European Standard shall be given the status of a national standard, either by public
17、ation of an identical text or by endorsement, at the latest by February 2009 and conflicting national standards shall be withdrawn at the latest by February 2009. This document includes Amendment 1 approved by CEN on 2008-06-28. The start and finish of text introduced or altered by amendment is indi

According to edition 2005 the following fundamental changes are given: Consideration of the Directive 97/23/EC Pressure Equipment Directive (PED) and including of Annex ZB; Correction of some typing errors. This document has been

For assemblies with a heat output between 1.000 kW and 10 MW however no Harmonized European Standard does exist at the moment. The relevant clauses of EN 303-3:1998 can be taken as a
22、 basis to prove conformity with the essential requirements of the GAD.“ This European Standard specifies requirements for boilers operating with a temperature of 100 C and 110 C which are not covered by the Pressure Equipment Directive (PED, TS 110 C (according to the PED). According to the CEN/CENE

25、 and the rational energy usage for standard boilers and low temperature boilers (with boiler“ in the sense of boiler body“) from steel and cast iron to be equipped with separately marketed forced draught burners according to the relevant burner standards (for automatic forced draught burners for gas
26、eous fuels see EN 676 and for atomising oil burners see EN 267) up to a nominal heat output of 10 MW. They are operated, either with negative pressure (natural draught boiler) or with positive pressure (pressurised boiler) in the combustion chamber, in accordance with the boiler manufacturers instru
27、ctions.“ !This European Standard specifies requirements for boilers with normal operating temperatures between 100 C and 110 C and has a “dual structure“: For boilers where the shut off temperature of the safety temperature limiter does not exceed 110 C the Pressure Equipment Directive (PED) require
28、s“ Sound Engineering Practice“, For boilers where the shut off temperature of the safety temperature limiter exceeds 110 C this European Standard specifies the requirements of the PED as stated in Annex ZB. NOTE 1 The “maximum allowable temperature TS“ is defined in the PED and its Guidelines.“ Boil
29、ers in accordance with this European Standard are designed for the heating of central heating installations in which the heat carrier is water, and the maximum allowable operating temperature of which is up to 110 C and the maximum safety temperature limiter of 120 C. The maximum allowable operating
30、 pressure is 10 bar. This standard does not apply to gas boilers with atmospheric burners, boilers for solid fuels, oil or gas fired condensation boilers, boilers with oil vaporisation burners. For these boilers there are further requirements. For gas-fired central heating boilers equipped with a fo
