T/CHEAA 0026-2023
Basic Information
Scope
Scope: This document specifies the special requirements and test methods for water pipes, electrical safety, anti-scald protection, load-bearing capacity, remote control, drainage rate, package drop, casters, handles, and noise of foot massage devices (hereinafter referred to as foot spas) used in home environments. Main technical content: 4. Technical requirements 4.1 Working environment conditions The foot spa should be used under the following conditions: 1) Ambient temperature: 5°C to 40°C; 2) Relative humidity: less than 95% (at 25°C); 3) Atmospheric pressure: 86 kPa to 106 kPa. 4.2 Water pipes The connection of the water pipes should be firm and reliable, with good sealing and no leakage. 4.3 Electrical safety In addition to meeting the requirements of this document, the remaining requirements should comply with GB 4706.1 and GB 4706.10, where the test voltage for electrical strength in clause 13.3 is 3750 V. 4.4 Anti-scald protection 4.4.1 Over-temperature warning function When the water temperature exceeds the user-set temperature value, the user should be warned. The temperature difference between the warning temperature and the set temperature should not exceed 2°C. 4.4.2 Water temperature uniformity requirements The foot spa should have a water temperature uniformity device, with the maximum water temperature difference between different positions of the foot not exceeding 2°C. 4.4.3 Safety measures for water temperatures exceeding 50°C When the water temperature exceeds 50°C, the foot spa should shut down all functions. When the foot spa is shut down, the water temperature in the middle of the water volume should be in the temperature range of greater than or equal to 48°C and less than or equal to 50°C. 4.4.4 Safety measures for temperature sensor failures When the temperature sensor experiences short circuits or open circuits, the foot spa should shut down all functions. 4.5 Automatic massage components Th
