Other changes include some minor revisions to the test conditions and alterations to the test load to ensure that this remains harmonised with the IEC 60456 load for clothes washers.In summary, the main changes are as follows.1)General:more terms have been defined and some previous definitions have been streamlined, in addition to the correction of some symbols and equations;where possible, definitions and terms have been used in common with IEC 60456;the content has been organised into a more logical and simple structure, and repetitive sections have been removed.2)The conditions of measurement:the wording of various sections has been revised to reduce ambiguity;limits have been defined for water conductivity for auto-sensing dryers that are sensitive to conductivity, as well as methods to adjust conductivity where necessary;specifications of a nominal exhaust duct were included.3)Reproducibility and repeatability of test results:revision of the specification for the cotton test load to include suitable test materials which are currently available on the market;more careful definition of the process and conditions for pre-treatment, conditioningand normalisation.4)Test methods:accuracy of measurement has been defined for all instruments;limits and interpretations of the allowable final moisture content for each type of dryer are now defined;practical advice regarding the test procedure has been given with the aim of reducing ambiguity.TUMBLE DRYERS FOR HOUSEHOLD USE METHODS FOR MEASURING THE PERFORMANCE1ScopeThis International Standard is applicable to household electric tumble dryers of the automaticand non-automatic type, with or without a cold water supply and incorporating a heating device.The object is to state and define the principal performance characteristics of household electric tumble dryers of interest to users and to describe standard methods for measuring these characteristics.This standard is concerned neither with safety nor with performance requirements.This European Standard also specifies, as far as necessary, the test methods which shall be applied in accordance with the Commissions Directive 95/13/EC of 23 May 1995 implementing Council Directive 92/75/EEC with regard to energy labelling of household el
