EN 15502-2-1:2022 燃气中央供暖锅炉2 -1部分:具体标准C型电器和B2型,B3和B5电器的名义热输入不超过1 000 kw

This document specifies the requirements and test methods, as well as the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as "boilers". This document is intended to be used in conjunction with EN 15502-1:2021. This document covers gas-fired central heating boilers from the types C1 up to C(11) and the types B2, B3 and B5: NOTE 1 For further background information on appliance types see EN 1749:2020. a) that have a nominal heat input (on the basis of net calorific value) not exceeding 1 000 kW; b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437:2021; c) where the temperature of the heat transfer fluid does not exceed 105 °C during normal operation; d) where the maximum operating pressure in the water circuit does not exceed 6 bar; e) which can give rise to condensation under certain circumstances; f) which are declared in the instructions for installation to be either a "condensing" boiler or a "low temperature boiler" or a "standard boiler"; if no declaration is given the boiler is to be considered a "standard boiler"; g) which are intended to be installed inside a building or in a partially protected place; h) which are intended to produce also hot water either by the instantaneous or storage principle as a single unit; i) which are designed for either sealed water systems or for open water systems; j) which are either modular boilers, or non-modular boilers. k) which are from the types C(10) that are equipped with a gas-air ratio control and that have a ∆pmax, saf(min) of 25 Pa, and C(11) that have condensing boiler modules that are equipped with a gas-air ratio control and that have a ∆pmax, saf(min) of 25 Pa. NOTE 2 This document provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard, the risk associated with this alternative construction needs to be assessed. An example of an assessment methodology, based upon risk assessment, is given in Clause 11. This document does not cover all the requirements for: aa) appliances above 1 000 kW; ab) appliances that are intended to be connected to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex AB of EN 15502-1:2021); ac) appliances using flue dampers; ad) appliances of the types B21, B31, B51, C21, C41, C51, C61, C71, C81, C(12) and C(13); ae) C7 appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW; af) appliances incorporating flexible plastic flue liners; ag) C(10) boilers: 1) without a gas-air ratio control, or 2) which are non-condensing appliances, or 3) which have a maximum safety pressure difference at minimum heat input not equal to 25 Pa (∆pmax, saf(min)); ah) C(11) boilers that have boiler modules: 1) without a gas-air ratio control, or 2) which are non-condensing appliances, or 3) which have a maximum safety pressure difference at minimum heat input not equal to 25 Pa (∆pmax, saf(min)); ai) appliances intended to be connected to a flue having mechanical extraction; aj) surface temperatures of external parts particular to children and elderly people; ak) appliances that are intended to burn natural gases of the second family where hydrogen is added to the natural gas; al) appliances equipped with an adaptive combustion control function (ACCF); am) boilers intended to be installed in areas accessible to elderly people and children.

Gas-fired central heating boilers - Part 2-1: Specific standard for type C appliances and type B2, B3 and B5 appliances of a nominal heat input not exceeding 1 000 kW

EN 15502-1:2021/AC:2022 燃气式供热锅炉.第1部分:一般要求和测试 包含修改件AC,2022

This European Standard specifies the common requirements and test methods, as well as the classification, marking and energy labelling of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as “boilers”. This European Standard is to be used in conjunction with the specific Parts 2 (Part 2-1 and following ones). This European Standard applies to boilers of types B and C. NOTE For further background information on appliance types see CEN/TR 1749:2014 [1]. a) that use one or more combustible gases of the three gas families at the pressures stated in EN 437; b) where the temperature of the water is below or above 105 °C during normal operation; c) where the maximum operating pressure in the water circuit does not exceed 6 bar; d) which can give rise to condensation under certain circumstances; e) which are declared in the instructions for installation to be either a "condensing" boiler or a "low temperature boiler" or a "standard boiler" or an "other boiler". If no declaration is given the boiler is to be considered both a "standard boiler" and an "other boiler"; NOTE The Ecodesign Directive defines "other boilers", "low temperature boilers" and "condensing boilers". The Boiler Efficiency Directive defines "standard boilers", "low temperature boilers" and "condensing boilers". Depending on the legislation applied, a boiler can be both "a standard boiler" and an "other boiler"." f) which are intended to be installed inside a building or in a partially protected place; g) which are intended to produce also hot water either by the instantaneous or storage principle as a single unit. This European Standard applies to boilers designed for sealed water systems or for open water systems. NOTE This general standard and the specific standards (see Part 2) provide requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard or a specific standard, the risk associated with this alternative construction will need to be assessed. An example of an assessment methodology, based upon risk assessment, is given in Clause 11. This European Standard is not intended to cover appliances intended for connection to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex EE). This European Standard is not intended to cover appliances designed and constructed to burn gas containing toxic components.

BS EN 16583:2022 热交换器 液体循环房间风机盘管装置 声功率级的测定

1   Scope This document is applicable to hydronic fan coil units (FCU) as factory-made single assemblies which provide the functions of cooling and/or heating but do not include the source of cooling or heating. This document is applicable to both air free delivery and air ducted units with a maximum external static pressure due to duct resistance of 300 Pa max. This document specifies methods for the determination of the acoustical performance of fan coil units, defining standard working condition and installation. It is not the purpose of this document to specify the tests used for production or field testing. NOTE For the purpose of remaining clauses, the term “unit” is used to mean “fan coil unit”.
