Toilet Seat Mechanical Strength Test Machine IEC 60335-2-84 Mechanical Stresses Testing
Toilet Seat Mechanical Strength Test Machine IEC 60335-2-84 Mechanical Stresses Testing
Product information:
Standard:IEC 60335-2-84 “Household and similar electrical appliances-Safety-Party 2-84: Particular requirements for toilet appliances” clause 21.103.1&21.103.2. It used to check whether the toilet seats have adequate mechanical strength and are constructed to withstand repeated mechanical stresses that may be expected to occur during normal use.
Test Contents:
1. 1250N force test:
The appliance is subjected to an evenly distributed force of 1250N applied perpendicularly to the seat for 4s by a rubber disc having a thickness of 10mm, a diameter of 300 mm and a shore A hardness of 70°, with a steel disc having a thickness of 5mm and a diameter of 30mm attached on its upper surface. The test is carried out 20 000 times.
2. 890N force test:
The appliance is subjected to an evenly distributed force of 890N applied perpendicularly on each side of the seat for 1s with 0.5 s interval by a rubber disc having a thickness of 19mm, 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.
Technical Parameters:
| Test station | Two stations can be independently tested at the same time; (one station for 1250N force test , the other station for 890N force test) |
| Force applied method | Adopts the air cylinder drive method |
