This International Standard specifies test methods to measure the performance of electrically operated spray seats for household and similar use. This standard applies to spray seats including tank-type spray seats, instantaneous-type spray seats and combination-type spray seats. This document does not apply to the electrically operated spray seats that are intended for medical and/or assistive functions NOTE: This International Standard does not specify acoustical noise requirements for electrical spray seats. Acoustical noise measurements are specified in IEC 60704-1 and IEC 60704-2-x.
