This chapter of GB4706.1 is applicable except for the following content. 2.2.30 This article is replaced by the following content
Normal load refers to the load obtained when the electrical appliance operates under the following conditions. . The hand-held massage appliance works without any other external load except the vibrating head. The massage appliance for the feet of a seated person (one foot or both feet) has a heavy load of 5kg (evenly) on its foot pedal. Works under the condition of being distributed on an area of ??10cm
The massage belt applies a force of 200N to the belt in the horizontal direction, so that the belt works under the conditions of approximately symmetry on both sides of the roller. The massage cushion must be placed when people are sitting. Between the two layers of felt, the whole thing is placed on a flat horizontal surface, and a load of 80kg is evenly placed on an area of ??30cm×30cm. Each layer of felt is 25mm thick and weighs 4±0.4kg/m. Stretch at least 15mm all around.
