T/CZGX 001-2022 Smart toilet seat

Scope

Scope: This document applies to the production and use of intelligent toilets installed in civil or public buildings at an ambient temperature of 0-40°C, with a relative humidity of no more than 95%, and a water supply static pressure of 0.05-0.75 MPa, after being matched with corresponding accessories. Main technical content: This standard specifies the terms and definitions, product classification, technical requirements, test methods, inspection rules, marking and labeling, installation and use instructions, packaging, transportation, and storage for intelligent toilets. 1. Technical requirements include the following items: - For the ceramic toilet part: appearance quality, deformation, dimensions, thickness, dimensions of the intelligent toilet's drainage port, water seal, minimum through-diameter of the water trap, load-bearing capacity, flushing function, etc. - For the electronic cover plate part: material performance, waterproofing grade of the entire device, cleaning function, self-cleaning performance of the spray nozzle, warm-air drying function, seat heating function, water pressure resistance, water hammer resistance, mechanical strength, durability, power supply, electrical safety, automatic shutdown, unit-cycle energy consumption, rated power, etc. This standard further categorizes technical requirements for flushing average water consumption, cleaning average water consumption, and flushing function into grades, which are more stringent than the three-grade classification in the national standard, placing higher technical demands on enterprises' products. For example, it sets the criterion for flushing average water consumption to no more than 5.6L.
