AS NZS 60335.2.32:2020 pdf free download – Household and similar electricalappliances -Safety Part 2.32: Particular requirements for massage appliances.
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 x 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 x 100 mm x 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 101 The open-cell polyether has the following composition:
— cell count 18 per cm:
— specific mass 30 kgfm3
— hardness 120 N to 170 N at 40 % impression, measured according to ISO 2439.
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 x 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/rn2 ± 0,4 kg/rn2 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 x 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.
— it only contains circuits operating at safety extra-low voltage according to 8 1.4;
— it only contains low power circuits according to 19. 11. 1;
— it is dropped from a height of 1 m on a rigidly supported concrete surface 5 times, the appliance being held in different positions likely to occur. After the drops, the appliance or part of the appliance as relevant shall show no damage so that compliance with 15. 1 and 20.2 is not impaired:
— it has a maximum weight of 450 g when ready for use:
— it does not have sharp edges when ready for use. An edge with a radius of 1 mm or more is not considered a sharp edge.
21 Mechanical strength
This clause of Part 1 is applicable except as follows.
21.1 Addition:
Appliances intended to be used under the feet of a sitting person are loaded as specified for normal operation but with the mass increased to 90 kg. The mass is applied for 30 s.
Hand-held parts of appliances are also subjected to the test of 21. 101.
21.101 The hand-held part of the appliance is placed in a sling that is constructed by tying together the tour corners of a single layer of cheesecloth. The lowest point of the sling is suspended at a height of 900 mm above a concrete or similar hard surface.
The hand-held part of the appliance in the sling is dropped from a stationary position. The test is carried out a total of five times with the hand-held part of the appliance being positioned so that it falls onto the concrete surface in five different orientations.
The appliance shall not be damaged to such an extent that compliance with 8. 1 and Clause 29 is impaired.
22 Construction
This clause of Part 1 is applicable except as follows.
22.101 Appliances shall be constructed so that hair cannot be drawn into the appliance or be entangled in moving parts.
Compliance is checked by inspection.
22.102 Appliances that use water and in which air is circulated shall be constructed so that the water cannot penetrate into the motor and come into contact with live parts or basic insulation.
