31、ashing 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of an identical text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the lates
32、t 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 1458-1:1999. This document has been prepare
33、d under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This edition has been prepared to up
34、-date this European Standard in the following respects: a) electrical safety by calling up EN 60335-2-102, b) its normative references, and c) the CEN Member countries and their national situations. The test gases, test pressures and appliance categories given in this European Standard are in accord
35、ance with those specified in EN 437. The marking requirements in this European Standard take into account CR 1472. 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 specifies
36、 the requirements for rational use of energy. This European Standard covers type testing only. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus

38、 Scope This European Standard specifies the requirements and test methods for the construction, safety, and marking of domestic 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 appl
39、y to: a) catalytic combustion appliances; b) appliances designed exclusively for industrial purposes; c) appliances intended 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
40、air and products of combustion used for the drying process are dehumidified by cooling with water or air; e) appliances intended 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 indisp
