Scope

Main technical content: 1.1 Scope The product category is specified as intelligent toilets (including integrated and split-type intelligent toilets), with added technical requirements, test methods, and result calculation for the flushing noise and air blowing noise of intelligent toilets. 1.2 Terms and definitions Definitions are proposed for "tank-type intelligent toilets", "tankless intelligent toilets", "test period", "test operator", and "center of sound source localization". 1.4 Technical requirements The use conditions of the test environment are specified. Through the verification data of the flushing, cleaning, and drying noises of intelligent toilet samples, the flushing noise limits, cleaning noise limits, and air blowing noise limits for tank-type and tankless intelligent toilets are determined. The flushing noise limit for tank-type intelligent toilets refers to L50≤55 dB(A) and L10≤65 dB(A) as specified in GB/T 6952-2015 "Sanitary Ceramics". The flushing noise limit for tankless intelligent toilets is L50≤65 dB(A) and L10≤75 dB(A). 1.5 Sample installation and debugging Installation and positioning requirements for integrated and split-type intelligent toilets, as well as pre-test preparations, are proposed. The measurement of sound pressure level is proposed for flushing noise tests, cleaning noise tests, and air blowing noise tests, including the positioning and orientation of the microphone, the setting of various modes, and the setting of water pressure and static/dynamic pressure. The calculation methods for flushing noise, cleaning noise, and air blowing noise are proposed, including the average sound pressure level of the A-weighted time average on the measurement surface, background noise correction, test environment correction, and the average sound power level calculated from the cumulative percentage of the A-weighted sound pressure level on the measurement surface.
