13、gine heat pumps and domestic gas-fired washing and drying appliances”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2012, and conflicting national s
14、tandards shall be withdrawn at the latest by May 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 145
15、8-2:1999. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). The main purpose of this edition is to align the method of test more closely with that given in the equiv
16、alent electrical appliance standard, EN 61121. The Directive makes no specification in respect of the maximum rating of appliances falling within its scope. However, the scope of this standard has been limited to appliances having heat inputs not greater than 6 kW. The test gases, test pressures and
17、 appliance categories given in this European Standard are in accordance with those specified in EN 437:2003+A1:2009. The first part of the standard specifies the requirements and test methods for the construction, safety, marking and testing of the appliances. The second part of the standard specifi
18、es the requirements for rational use of energy and a method of measuring the gas and electrical energy consumptions which enables comparison of gas and electrical Tumble dryers. This standard covers type testing only. According to the CEN/CENELEC Internal Regulations, the national standards organiza
19、tions of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portug

21、estic direct gas-fired tumble dryers, of types B22Dand B23D, of nominal heat input not exceeding 6 kW, hereafter referred to as “appliances“. This European Standard does not apply to: a) catalytic combustion appliances; b) appliances designed exclusively for industrial purposes; c) appliances intend
22、ed to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere; d) appliances of the condensing type wherein the heated air and products of combustion used for the drying process are dehumidified by cooling with water or air; e) appliances in
23、tended to be used in vehicles or on board ships or aircraft. This European Standard covers type testing only. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、t given in 4.2. The gas energy consumption of the appliance shall be recorded separately from the electrical energy consumption. The appliance shall have a gas energy consumption (based on gross calorific value) not exceeding 1,11 kWh/kg of standard load. BS EN 1458-2:2011EN 1458-2:2011 (E) 5 4.2 Me
27、thod of test 4.2.1 General test conditions The electrical energy consumption shall be measured in accordance with EN 61121 and the energy consumption recorded in kWh. The volume of gas utilised during this test is measured with a gas meter and the gas energy consumption (in kW/h) determined as descr
28、ibed in 4.2.2. The tests shall be carried out with all reference gases according to the category of the appliance (see EN 1458-1:2011). 4.2.2 Determination of gas energy consumption The gas energy consumption, Eg, is determined in kW/h using the following equation: Eg= sc0,278 HV (1) where Vcis the
29、volume of dry gas consumed, corrected to reference conditions (15 C and 1 013,25 mbar), in cubic metres; Hs is the gross calorific value of the dry test gas under reference conditions (15 C and 1 013,25 mbar), in megajoule per cubic metre. NOTE Where the test gas G 20 has a methane content of less t
30、han 99,5 % care should be taken to ensure that the calorific value of this gas is known and used in the above equation. Vcis determined from the measured volume, by the following equation: Vc= Vmes 013,251wappp + g273,15288,15t+(2) where Vmesis the measured gas volume, in cubic metres; pais the atmo
31、spheric pressure, in millibars; p is the gas supply pressure measured at the same point as that used in the heat input determination, in millibars; pwis the partial vapour pressure, in millibars; tgis the gas temperature measured at the same point as that used in the heat input determination, in deg
