IEC 60704-2-16:2019 applies to single-unit electric washer-dryers for household and similar use intended for placing on the floor against a wall, for building-in or placing under a counter, a kitchen worktop or under a sink, for wall-mounting or on a counter. This standard is concerned with objective methods of engineering accuracy for determining sound power levels of airborne acoustical noise. Requirements for the declaration of noise emission values are not within the scope of this document. This part is intended to be used in conjunction with IEC 60704-1:2010.
