3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
3.1 Definitions relating to physical characteristics
3.1.9 replacement:
normal operation
operation of the appliance under the following conditions:
Hand-held appliances are operated with no load other than that imposed by the vibrator
head.
Appliances intended to be used under the feet of a sitting person are operated with the platform loaded with a mass of 5 kg, evenly distributed over an area of 100 mm × 300 mm.
Appliances incorporating heating elements are operated with two sheets of thermal insulation placed on the foot platform. The sheets of thermal insulation are made of open cell polyether and have dimensions approximately 300 mm × 100 mm × 15 mm. They are positioned together and loaded with an evenly distributed mass of 10 kg. Appliances having a liquid container are filled with water in accordance with the instructions and loaded with a mass of 10 kg.
Note: The open-cell polyether has the following composition:
cell count per cm;
specific mass kg/m3
hardness 120 N to 170 N at 40 % impression, measured according to GB/T 10807-1989.
Appliances intended to be used under the feet of a standing person are operated with the
platform loaded with a mass of 90 kg, evenly distributed over an area of 200 mm × 300 mm.
Massage belts are operated with the belt loaded with a force of 200 N. The force is applied in a horizontal direction by means of a roller, the belt being approximately symmetrical about the roller.
Massage pads are operated with the pad positioned between two layers of felt and placed on a flat horizontal surface. The felt has a thickness of approximately 25 mm, a mass of
4 kg/m2 ± 0.4 kg/m2 and extends at least 15 mm beyond the edges of the pad. The upper layer of felt is loaded with a mass of 90 kg, evenly distributed over an area of 300 mm × 300 mm.
Massage chairs are operated without load.
Massage beds are loaded with a mass of 90 kg, evenly distributed over an area of 0.5 m × 2 m.
Foot massage appliances that use water are filled with water at a temperature of 40 °C ± 2 °C.
