this European standard specifiers the requirements and test method for the construction , the safety and the rational energy usage of an assembly made up of a boiler body complying with EN 303-1(1) and a forced draught gas burner complying with EN 676 usuing combustible gases , herafter reffered to a “boiler”. This European standard applies to a boiler. - With a nominal output not exceeding 1000 kw . This European standard does not contain all the necessary requirements for : - Assembles designed as units; - Condensing boilers and low temperature boilers - Boilers intended to be installed in the open - Bollers pemanenty fitted with more than one flue outlet; - Boilers fitted with a draught diverter ; - Boilers intended t be connected to a common flue having mechanical extraction. This European standard does not apply to living space dedicated boilers of the boiler body has already been tested with a liquid fuel burner in accordance with en EN_303-2 and EN 304 only the tests described in annex G need to beperformed . in the case of a range of boilers, see annex F. This European standard does not contain all the necessary requirements for low temperature boilers. Nevertheless, the testing methods defined by this European standard for the determination of useful efficiencies can be used for the determination of useful efficiencies can be used for low temperature boilers after being adapted in accordance with annex H . This European standard only covers type testing. 2005 English; French 35000.00 0 162 168 C NL EN 303 4 : 2005 NL TC EO 91.140.10 60.60 Mechanical Systems and Components for General Use Heating boilers - Part 4: Heating boilers with forced draught burners - Special requirements for boilers with forced draught oil burners with outputs up TO 70 KW and a maximum operating pressure OF 3 BAR - terminology, special requirements,testing and mar This scope is applicable to heating boilers with forced draught oil burners up to nominal heat output of 70 Kw , they are operated , either with negative pressure (antural draught boiler ) or with positive pressure ( pressurized boiler ) in the cpmbustion chamber in accordance with the boiler manufacturer s instruction. This standard specifies the necessary terminology the requirements on the materials and testing of them and marking requirements for heating boilers. The boilers are capable of operating with either conventional flues or low level discharge flues as specified by the boiler manufacturer . The boilers are provided as matched units with factory fitted burnes for burning kessene or gas oil , when using a low level flue gas discharge only kerosene may be used ( see annex b) . The requirements of this standard apply to heating boilers which are tested on an authorized test in accordance with EN 304 and annex b of this standard . Boilers on accordance with this standard are designed for the heating of central heating installation in which the heat carrier is water and the temperature of which is restricted to 95 c at normal operating conditions. For boilers with a built-in or attached water heater ( storage or continuous flow heater ) this standard only applies to the parts of water heater which are necessarily subject the the operating conditions of the heating boiler (heating part). This standard does not apply to gas boilers with atmospheric burners, boilers for solid fuels, oil or gas fired condensation boilers, boilers with oil vaporization burners and low temperature boilers. For these boilers there are further requirements. NOTE low temperature boilers are those operating with a ( water ) variable temperature up to 40 C or less,ore those which cannot be set at a temperature higher than 55 C. 2005 English; French 35000.00 0 163 169 C NL EN 303 5 : 2005 NL TC EO 91.140.10 60.60 Mechanical Systems and Components for General Use Heating boilers - Part 5: Heating boilers for solid fuels, hand and automatically fired, nominal output of up to 300 KW -Terminology, requirements, testing and marking This European Standard applies to heating boilers including safety devices up to a nominal heat output of 500 kW which are designed for the burning of solid fuels only and are operated according to the instructions of the boiler manufacturer. This European Standard deals with significant hazards, hazardous situations and events relevant to heating boilers used as intended and under the conditions foreseen by the manufacturer (see Clause 4). The boilers may operate under natural draught or forced draught. The stoking may work manually or automatically. NOTE This European Standard deals with boilers which are both within and outside of the scope of the Machinery Directive 2006/42/EC. This European Standard contains requirements and test methods for safety, combustion quality, operating characteristics, marking and maintenance of heating boilers. It also covers all external equipment that influences the safety systems (e.g. back burning safety device, integral fuel hopper). This European Standard covers only boilers that include burners as a unit. The standard applies to the combination of a boiler body with a solid fuel burner according to EN 15270 as a unit only when the whole unit is tested in accordance with this European Standard. Heating boilers in accordance with this European Standard are designed for central heating installations where the heat carrier is water and the maximum allowable temperature is 110 °C, and which can operate at a maximum allowable operating pressure of 6 bars. For heating boilers with a built-in or attached water heater (storage or continuous flow heater), this European Standard only applies to those parts of the water heater which are necessarily subject to the operating conditions of the heating boiler (heating part). This European Standard does not apply to: - heating boilers and other heating appliances which are also designed for the direct heating of the place of installation; - cooking appliances; - the design and construction of external fuel storage and transportation devices prior to the safety devices of the boiler; - room sealed applications; - condensing boilers. This European Standard specifies the necessary terminology for solid fuel heating boilers, the control and safety related requirements, the design requirements, the technical heating requirements (taking into account the environmental requirements) and testing, as well as the marking requirements. This European Standard is not applicable to heating boilers which are tested before the date of its publication as an EN (European Standard). 2005 English; French 35000.00 0 164 170 C NL EN 303 6 : 2005 NL TC EO 91.140.10 60.60 Mechanical Systems and Components for General Use Heating boilers- Part 6: heating boilers with forced draught burners - Specific requirements for the domestic hot water operation of combination boilers with atomizing oil burners of nominal heat input not exceeding 70 KW. This document is composed of two parts. The first part supplements EN 303-1, EN 303-2, EN 303-4 and EN 304, hereafter called boiler standards. It specifies the supplementary requirements and tests for the construction, safety, rational use of energy, fitness for purpose, classification and marking related to the domestic hot water operation of oil-fired water heaters and combination boilers. The domestic hot water is produced on either the instantaneous or storage principle. The domestic hot water production is integrated or coupled, the whole being marketed as a single unit. The second part covers the energy performance of domestic hot water production of the appliances covered by the first part. This second part sets out a method for assessing the energy performance of the appliances. It defines a number of daily tapping cycles for each domestic hot water use such as kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of combination boilers and water heaters to be compared and matched to the needs of the user. The heat output of the appliances covered by this standard does not exceed 400 kW. In the case of combination boilers, with or without storage tank, domestic hot water production is integrated or coupled, the whole being marketed as a single unit. This standard only covers type testing. 2005 English; French 25000.00 0 165 171 C 94 051 : 2000 NL TC FP 93.020 60.60 Construction Materials and Building Soils: investigation and testing - Détermination of Atterberg's limits Sols : reconnaissance et essais - Détermination de la teneur en eau pondérale des matériaux - Méthode par étuvage.
