T/CHEAA 0021-2023 Ultrasonic Pore Cleaning Device
T/CHEAA 0021-2023
Basic Information
Scope
Main technical content: This document specifies the technical requirements, test methods, inspection rules, and marking, instructions, packaging, transportation, and storage requirements for ultrasonic pore cleansers. This document applies to ultrasonic pore cleansers that use flat, circular P-type ultrasonic piezoelectric transducers with an acoustic working frequency below 100 kHz and generate continuous wave ultrasonic energy through longitudinal piezoelectric effects, intended for pore cleansing and similar applications. Ultrasonic beauty devices that act on human skin through longitudinal piezoelectric effects are also applicable to this document. This document does not apply to: - Ultrasonic beauty devices corresponding to ultrasonic transducers with a frequency ≥ 100 kHz; - Ultrasonic beauty devices that act on human skin through radial piezoelectric effects; - Medical and physiotherapy-related ultrasonic devices/equipment used on human skin.
