60661 © IEC:1999– 3 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________METHODS FOR MEASURING THE PERFORMANCEOF ELECTRIC HOUSEHOLD COFFEE MAKERSFOREWORD1)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 specifications, technical reports or guides and they are accepted by the NationalCommittees 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 60661 has been prepared by subcommittee 59G: Small kitchenappliances, of IEC technical committee 59: Performance of household electrical appliances.This second edition cancels and replaces the first edition published in 1980 and amendment 1(1992). It constitutes a technical revision.The text of this standard is based on the following documents:FDISReport on voting59G/99FDIS59G/105/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with ISO/IEC Directives, Part 3.The committee has decided that this publication remains valid until 2003. At this date, inaccordance with the committee's decision, the publication will be·reconfirmed;·withdrawn;·replaced by a revised edition, or·amended.SIST EN 60661:2002
60661 © IEC:1999– 5 –METHODS FOR MEASURING THE PERFORMANCEOF ELECTRIC HOUSEHOLD COFFEE MAKERS1 Scope and objectThis International standard applies to electric coffee makers for household and similar use. Itdoes not apply to appliances designed exclusively for commercial or industrial use.The object of this standard is to state and to define the main performance characteristics,which are of interest to the user and to describe the standard methods for measuring thesecharacteristics.This standard is concerned neither with safety nor performance requirements.Taking into account the
degree of accuracy and repeatability, due to variations in time andorigin of test materials and ingredients and the influence of the subjective judgement of testoperators, the described test methods may be applied more reliably for comparative testing ofa number of appliances at approximately the same time, in the same laboratory, by the sameoperator and with the same utensils, rather than for testing single appliances in differentlaboratories.NOTE 1
Similar use denotes use in premises other than household, for example offices, where the appliance isused in a similar way to normal household use.NOTE 2
The measuring methods of this standard are
specific to coffee makers with a view to the following typesof coffee percolator, filter type coffee makers and espresso coffee makers; they may, however, be used for coffeemakers having other systems, as far as this is reasonable.2 Normative referencesThe following normative documents contain provisions which, through reference in this text,constitute provisions of this International Standard. For dated references, subsequentamendments to, or revisions of, any of these publications do not apply. However, parties toagreements based on this International Standard are encouraged to investigate the possibilityof applying the most recent editions of the normative documents indicated below. For undatedreferences, the latest edition of the normative document referred to applies. Members of IECand ISO maintain registers of currently valid International Standards.ISO/DIS 3310-1, Test sieves –

In some countries, this type of coffee maker is named “coffee brewer”.3.3filter coffee makercoffee maker with separate containers for water and for the coffee brewed and with a filterarranged above the coffee container. The heated water passes once through a filter containingground coffee into a container3.4espresso coffee makercoffee maker with water heated and forced through ground coffee and filter by steam pressureor mechanical pump4 Grinding degreesFor the purpose of performance testing of coffee makers, the grinding degrees are defined asfollows.a)COARSEmore than 50 % of the grounds are larger than 0,71 mm;b)MEDIUMmore than 50 % of the grounds are larger than 0,355 mm but smaller than0,71 mm;c)FINEmore than 50 % of the grounds are smaller than 0,355 mm.Test sievesMesh size of sievemm0,710,355NOTE

In Japan the cold water temperature is 20 °C ± 3 °C.–input: rated power input ±1 %;–frequency: ±1 %;–test room: substantially draught-free;–during the test the ambient temperature shall be kept at a constant level, with admissibledeviations ±2 °C;–placing of the appliance: on a matt black painted wooden support, projecting beyond theappliance by at least 50 mm on all sides and at least 300 mm from the walls.7 Overall dimensionsThe overall dimensions of the appliance, length, height, width or diameter, including anycontrols, handles, control knobs or other protrusions, the cord guard of any flexible cord andthe appliance connector of any cord set supplied with the appliance, shall be measuredand indicated in millimetres.For espresso coffee makers, filter boxes and steam tubes are not taken into account.8 MassThe mass of the empty appliance with flexible cord is measured and indicated in kilograms tothe nearest 0,05 kg.The mass is measured with the appliance fitted with all supplied accessories and ready for use.SIST EN 60661:2002
