    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard applies to standard boilers and low temperature boilers with forced draught burners with a nominal heat output not exceeding 1 000 kW, which are operated either with negative pressure (natural draught boilers) or with positive pressure (pressurised boiler) in the combustion 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. Particular requirements for boilers which can be used with open vented systems are contained in EN 303 4. The requirements of this standard apply to heating boilers which are tested on an authorised test rig. Boilers in accordance with this 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 restricted to 100 °C. The maximum allowable operating pressure is 8 bar. For boilers with a built in or attached water heater (storage or continuous flow heater) this standard only applies to the parts of the water heater which are necessarily subject to 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 condensing boilers and boilers with oil vaporisation burners. For these boilers there are further requirements.

    Heating boilers with forced draught burners — Specific requirements for the domestic hot water operation and energy performance of water heaters and combination boilers with atomizing oil burners of nominal heat input not exceeding 70 kW

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This standard is composed of two parts. The first part supplements EN 303-1, EN 303-2, EN 303-4 and EN 304/A1 and EN 304/A2 hereafter called boiler standards. lt 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 like 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 appliances covered by this standard shall not have : ⎯ a heat input exceeding 70 kW; and ⎯ a hot water storage tank capacity (if any) exceeding 500 litres. 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 does not apply to appliances which operate independently of each other — a boiler and a water heater — even if they have a common flue. Neither does the standard apply to a boiler and water storage tank which are not included within the same casing. This standard only covers type testing.

    Beskrivelse
    This part of the standard specifies requirements for construction, design, performance, marking and user information for ear-muffs fitted to an industrial helmet which complies with EN 397. In particular, it specifies the sound attenuation of the helmet mounted ear-muffs, measured in accordance with EN 24869-1. Because one model of ear-muffs designed to be attached to an industrial safety helmet can be fitted to a number of helmet models and sizes, this part of the standard sets out a series of physical and acoustic requirements for the ear-muffs when fitted to the specified model(s) or size(s) of helmet. All requirements apply to the ear-muffs fitted to one of the specified models or sizes of helmet (the basic combination), and an abbreviated set of requirements apply to the same model of ear-muffs when fitted to the other specified models or sizes of helmet (the supplementary combinations). Information on the range models of helmet tested with the ear-muffs, and for which the combination satisfied this standard, is required to be made available. Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the wearer, the device and where possible the working environment in which the device is likely to be used (see Annex ZA and prEN 458)
