IEC 60335-2-84-2019 pdf download.Household and similar electrical appliances — Safety — Part 2-84: Particular requirements for toilet appliances
Appareils électrodomestiques et analogues — Sécurité — Partie 2-84: Exigences particulières pour les appareils de toilettes.
The temperature of the water supplied by spray seats shall not exceed 65 °C.
19.101 The appliance is supplied at rated voltage and operated under normal operation. Any fault conditions that can be expected in normal use are applied one at a time.
NOTE Examples of fault conditions are
— failure of thermostats,
— failure of relays;
— open-circuiting or short-circuiting of components;
– stopping programmers in any position.
20 StabilIty and mechanical hazards
This clause of Part 1 is applicable.
21 Mechanical strength
This clause of Part 1 is applicable except as follows.
21.1 Addition:
Compliance is also checked by the tests of 21. 101 and 21.102.
21.101 The appliance is subjected to an evenly distributed force of 1 500 N applied perpendicularly to the seat, the bowl cover being open for 10 mm.
The test is repeated with the bowl cover closed.
A force of 150 N is then applied for 5 s to the front edge of the bowl cover or seat in a right or left direction parallel to the hinges, whichever is more unfavourable. Then the bowl cover or seat is slowly raised and lowered. The test is carried out five times.
The bowl cover or seat is then raised and the force of 150 N is applied for I mm to its front edge in a direction perpendicular to its plane. For spray seats and heated seats that are installed onto the toilet bowl or integrated with the toilet bowl, the force of 150 N is applied, and the bowl cover is lifted to less than an angle of 120°. If detachable parts are removed, no more force is applied.
The appliance shall not be damaged to such an extent that compliance with 8.1, 15.1, 16.3, 27.5 and Clause 29 is impaired.
21.102 The excrement tank is completely filled with water and the appliance placed in a room having a temperature of approximately —15 C. When the water is completely frozen, the appliance is allowed to warm up until the ice has melted. The test is carried out three times.
The appliance shall not be damaged to such an extent that compliance with 8.1, 15.1. 16.3 and 27.5 is impaired.
21.103 Spray seats, heated seats, enclosures and seats shall have adequate mechanical strength and be constructed to withstand repeated mechanical stresses that may be expected to occur during normal use.
Compliance is checked by the tests of 21.103. 1 and 21.103.2.
21,103.1 The appliance is subjected to an evenly distributed force of 1 250 N applied perpendicularly to the seat for 4 s by a rubber disc having a thickness of 10 mm, a diameter of 300 mm and a shore A hardness of 70’, with a steel disc having a thickness of 5 mm and a diameter of 300 mm attached on its upper surface. The test is carried out 20 000 times.
The appliance shall not be damaged to such an extent that compliance with 8.1, 15.1, 16.3. 27.5 and Clause 29 is impaired.
21,103.2 The appliance is subjected to an evenly distributed force of 890 N applied perpendicularly on each side of the seat for I s with a 0,5 s interval by a rubber disc having a thickness of 19 mm, a diameter of 76 mm and a shore A hardness of 70°. The test is carried out 10 000 cycles. One cycle consists of applying the force to one side and the other.
The appliance shall not be damaged to such an extent that compliance with 8.1, 15.1, 16.3, 27.5 and Clause 29 is impaired.
22 Construction
This clause of Part 1 is applicable except as follows.
22.2 Modification:
Class I appliances shall not incorporate an appliance inlet.
22.24 Replacement:
Appliances shall not incorporate bare heating elements located in excrement tanks or as water heaters for spray seats.IEC 60335-2-84-2019 pdf download.
