which national standards conflicting with the EN have to be withdrawn (dow) 2007-03-01 This part has to be used in conjunction with EN 60335-1, Household and similar electrical appliances – Safety – Part 1: General requirements It was established on the basis of the 2002 edition of that standard Amendments and revisions of Part have also to be taken into account and the dates when such changes become applicable will be stated in the relevant amendment or revision of Part This part supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into the European Standard: Safety requirements for electrical heat pumps, air-conditioners and dehumidifiers When a particular subclause of Part is not mentioned in this part 2, that subclause applies as far as is reasonable When this standard states "addition", "modification" or "replacement", the relevant text of Part is to be adapted accordingly NOTE The following numbering system is used: - subclauses,

uncertainty is depending on the standard deviation of reproducibility σ R0 of the measurement method and the standard deviation σ omc representing the instability of the operating and mounting

operating conditions or dB for very instable sources The total measurement uncertainty for the A-weighted emission sound pressure level is of the same order as the one for the respective sound power level measurement ZAB.2.4 Information to be recorded The information to be recorded covers all the technical requirements of this noise test code Any deviations from this noise test code or from the basic standards upon which it is based are to be recorded together with the technical justification for such deviations ZAB.2.5 Information to be reported The information to be given in the test
