IEC 62512:2012 provides a globally applicable and agreed method to test the washing and drying function of washer-dryers. Although this standard is based on IEC 61121:2012 on tumble dryers and IEC 60456:2010 on clothes washers, it specifies the conditions needed to test the combined function of washing and drying. The main elements of this standard are: - the definition of the loads to be tested in continuous and interrupted operation cycles; - the method for testing automatic and not automatic operation of the drying cycles; - the way to handle the load for interrupted operation cycles; - the correction to be applied to test results for continuous and interrupted operation cycles.
