Product Description
1.Specifications
1. soft closing, can support 4kgs
2. more than 80000 cycles
3. pass TUV test, ISO9001/14001
4. stainless steel, high class
2.Design Torque:
10-30KGF.CM
3.Damper units not to contain: Cadmium, Mercury, Lead, Chromium VI, PBB, PBDE (RoHS banned substances)
4.Closing Time Test
1.Testing to be performed in conditions 20 +/-2
2.degrees C and 65 +/- 5 % Relative Humidity. Damper to be stored in this
3.environment a minimum of 2 hours before testing.
4.Set up torque arm to apply the design torque to
the damper (as per above)
Position 1: Measure the closing time from a position of 70 degrees to 0 degrees (where 0 degrees is the closed position).
The closing time should be in the range of 6 to 12 sec.
Position 2: Measure the closing time from a position 15 degrees to 0 degrees (where 0 degrees is the closed position).
The closing time should be 0.4 sec or more. Repeat the closing time test for both positions on 30 dampers and record the results.
5.High Temperature test
Expose damper to an atmosphere of 50+/-5 degrees
C for 96 hours. Remove damper and store at 20 +/-2 degrees C and 65 +/- 5 %
Relative Humidity for 1 hour.
Perform closing time test at design torque for that model damper
Damper shall pass closing time test
6.Low Temperature test
Expose damper to an atmosphere of -10+/-5
degrees C for 96 hours. Remove damper and store at 20+/-2 degrees C and 65 +/-
5 % Relative Humidity for 1 hour.
Perform closing time test at design torque for that model damper
Damper shall pass closing time test
7.Humidity Test-
Expose damper to an atmosphere of 90+/-5 % RH for 96 hours. Remove damper and store at 20 +/-2 degrees C and 65 +/- 5 %
Relative Humidity for 1 hour.
Perform closing time test at design torque for that model damper
Damper shall pass closing time test.
8. Thermal Shock Test
Expose damper to 5 thermal shock cycles as
follows: -10 degrees C for 7.5 hrs, 20 degrees C for 0.5 hrs, 50 degrees C for
15.5 hrs (24h/ cycle)
Remove damper and store at 20 +/-2 degrees C and 65 +/- 5 % Relative Humidity for 1 hour.
Perform closing time test at design torque for that model damper
Damper shall pass closing time test.
9. Life Cycle Test
1.Damper units to be assembled with toilet seat and tested on open /close cycle tester. Machine lifts ring and cover to above 70 degrees
and allows ring and cover to fall to fall to 0 degrees before
starting the next cycle.
2.Lid and cover to pass 50,000 cycles without damage or breaking of dampers.
If slow close time falls below 2 sec (for ring or cover) before 50,000 cycles are complete this is considered a failure.
