Description
This clause of IEC 60704-1:2021 is applicable except as follows:
Addition:
These particular requirements apply to single-unit electric water heaters 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.
NOTE 1 Conventional electric water heaters that make use of the Joule effect in electric resistance heating elements normally do not produce any noise emissions. However, there are products with noise-producing components on the market. Examples of such components are motors and pumps e.g. for increasing water pressure.
NOTE 2 Noise of control elements is disregarded because of the sporadic character and its normally very low sound level.
This document does not apply to:
– combustion water heaters;
– water kettles;
– heat pump water heaters;
– conventional electric storage water heaters as defined in IEC 60335-2-21:2012, Clause 1;
– instantaneous electric water heaters without any noise-producing components such as
motors and pumps.
