Scope

Scope: This document specifies the terms and definitions, evaluation index system, and evaluation methods for the "Leader" standard evaluation of showerheads. This document is applicable to the enterprise-level evaluation of showerhead products used in bathrooms (restrooms, showers), shower rooms, and other sanitary facilities installed in buildings, where the working pressure (static pressure) does not exceed 1.0 MPa and the medium temperature ranges from 4°C to 90°C. This document is not applicable to showerhead products with built-in electric heating devices. Related institutions may refer to this document when formulating enterprise-level "Leader" evaluation programs, and enterprises may also use it as a reference when developing their own standards. Main technical content: (1) Basic requirements; (2) Evaluation index system: 1) Basic indicators: a) Appearance b) Thread c) Assembly d) Water pressure resistance e) Valve body sealing performance f) Flow rate g) Sensitivity h) Resistance to installation loads i) Resistance to use loads j) Coating/plating adhesion strength k) Safety performance l) Showerhead sealing performance m) Cold/heat fatigue resistance n) Overall tensile strength o) Temperature drop p) Anti-siphoning of handheld showers q) Average spray angle r) Spray uniformity s) Spray force 2) Core indicators: a) Showerhead water efficiency rating b) Flow rate uniformity c) Surface corrosion resistance d) Lifespan 3) Innovative indicators: a) Spray force (benchmarked against international advanced levels) b) Temperature drop (benchmarked against international advanced levels) c) Fidelity d) Showerhead operating force e) Locking strength of telescopic shower rods f) Torque of showerhead sockets g) Load capacity of mobile frames h) Bending resistance of showerhead arms i) Impact resi
