Verification of refrigerated appliance rated energy consumption.

Author(s) : SLUIS S. M. van der

Summary

The European Commission's directive on energy labelling of refrigerating appliances calls upon all member states to enforce full compliance to the directive. This includes the checking of the energy consumption as declared by the manufacturer, on the basis of the European Standard EN 153. The standard EN 153 stipulates that the rated value is accepted as long as the difference between measured and rated values does not exceed 15%. At higher tolerances, three extra samples should be measured for which - on average - a tolerance of maximum 10% is accepted. For the Dutch ministry of economic affairs, TNO MEP undertakes a verification campaign of refrigerating appliance energy labels. Measurements carried out in 1997 and 1998 on 47 models show that conformity between rated and measured energy consumption is above 80%. But consumer organisations in EU member states claim high percentages (up to 89% for certain categories) that do not conform to the rated energy consumption (not taking account of the 15% tolerance). The discussion now focuses on the necessity of 15% tolerance in the European Standard. TNO MEP will deal with the subject and play as a co-ordinator for interlaboratory comparison of test results.
