60531 © IEC:1999– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION___________HOUSEHOLD ELECTRIC THERMALSTORAGE ROOM HEATERS –METHODS FOR MEASURING PERFORMANCEFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60531 has been prepared by subcommittee 59C: Heatingappliances, of IEC technical committee 59: Performance of household electrical appliances.This second edition cancels and replaces the first edition published in 1976 and constitutes atechnical revision.The text of this standard is based on the following documents:FDISReport on voting59C/85/FDIS59C/86/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.Annexes A and B form an integral part of this standard.Annexes C, D, E and F are for information only.SIST EN 60531:2002

60531 © IEC:1999– 7 –HOUSEHOLD ELECTRIC THERMALSTORAGE ROOM HEATERS –METHODS FOR MEASURING PERFORMANCE1 ScopeThis International Standard applies to electric storage heaters having a daily operating cycleand intended to heat the room in which they are located.NOTE 1 – This standard does not apply to heating appliances incorporated in the building structure, to centralheating systems or to floor heating installations.NOTE 2 – If an appliance is intended to be operated as a storage heater or as a direct-acting room heater, it is alsotested in accordance with IEC 60675 [1]* .This standard defines the main performance characteristics of storage heaters and specifiesmethods for measuring these characteristics, for the information of users.NOTE 3 – Information which may be of interest to the consumer is listed in annex D.This standard does not specify values for performance characteristics.NOTE 4 – This standard does not deal with:–safety requirements [2];–acoustical noise [3].2 Normative referenceThe following normative document contains provisions which, through reference in this text,constitute provisions of this standard. At the time of publication, the edition indicated was valid.All normative documents are subject to revision, and parties to agreements based on thisstandard are encouraged to investigate the possibility of applying the most recent edition of thenormative document indicated below. Members of IEC and ISO maintain registers of currentlyvalid International Standards.IEC 60584-1:1995, Thermocouples – Part 1: Reference tables3 DefinitionsFor the purposes of this International Standard the following definitions apply.3.1storage heaterheater which stores heat obtained from electric energy by charging an accumulating corebefore a heat demand in a room occurs, the heat being discharged at any time___________* Figures in square brackets refer to the bibliography in annex F.SIST EN 60531:2002

However, fans are supplied at rated voltage.NOTE – Steady conditions may not be established until the end of the charging period.Supply voltages are kept within ±1 %.6.2 Test roomsAll tests except those of clauses 9 and 10 are carried out in a draught-free room in which theambient temperature is maintained at 20 °C ± 1 °C, measured at a distance of approximately2 m from the appliance and 1,5 m above the floor.NOTE – Care has to be taken to ensure that the measurement point is not directly influenced by the heat output.SIST EN 60531:2002

60531 © IEC:1999– 13 –The tests of clauses 9 and 10 are carried out in a calorimeter as specified in annex A. Thetemperature of the air entering the calorimeter is maintained at 20 °C ± 1 °C.The tests of clause 13 are carried out in a climatic test room as specified in annex B.6.3 Position of the storage heaterFor the tests of clauses 8, 11 and 12, built-in appliances are installed in accordance with themanufacturer’s instructions, other appliances being placed in a test corner.Dull black painted plywood approximately 20 mm thick is used for the test corner and for theinstallation of built-in appliances.The test corner extends at least 300 mm beyond the appliance. A wooden board having aheight of 120 mm and a thickness of 15 mm, is fixed along the full length of the walls of the testcorner and in contact with the floor.Appliances are positioned in the test corner as follows:-appliances normally used on a floor are placed on the floor as near to the walls as possibleunless otherwise stated in the installation instructions;-appliances normally fixed to a wall are mounted on one of the walls and as near to the otherwall and to the floor as is likely to occur in normal use, unless otherwise stated in theinstallation instructions.For the tests of clauses 9, 10, 13 and 14, the appliance is placed on a trolley as shown infigure A.1.Appliances intended to be fixed to a wall are fixed to a board on the trolley. The dimensions ofthe board are approximately equal to the length and height of the appliance but include themounting height of the appliance above the floor.6.4 Initial conditionsAt the beginning of each test, the storage heater is at room temperature.6.5 Charging controlCharging controls are set to the maximum position.If an external signal is required in order to operate the appliance, this is provided in accordancewith the instructions.6.6 PreconditioningIf the installation instructions state that preconditioning is necessary, this preconditioning iscarried out before testing.6.7 Ambient temperature thermostatAny ambient temperature thermostat is rendered inoperative except for the tests of clause 13.SIST EN 60531:2002
