Product Description
CY103 vulcanized rubber brittle single test is to measure the temperature measuring instrument vulcanized rubber specimen under specified conditions after showing destroyed by the impact of the maximum temperature. Is brittle temperature. Can be non-rigid plastics and other materials used in low temperature conditions to compare the performance of identification.
Test method
at low temperature,With a certain energy, the speed of punch hammer impact compression specimens, The temperature at which the for the failure rate of 50%
Parameter
1.Specimen size:length 50±1mm,width 6±0.5mm,thickness 0.5±0.05mm.
2.Sample should be no crack, air bubble, pinhole and other defects, surface is smoothness
3.Enough quanitty:
note:1) thickness of specimen allow 0.3~0.7mm,the test results of different thickness can not compare
2) Sample surface requirements and sampling according to product standards
4 .punch hammer impact W=50±2.0kg-cm,speed V=2±0.05m/s;
5.punch bottom should keep parallel with specimen table-board
6.keep good heat preservation tank and mixer
7.temperature range:-80ºC-0ºC
8.refrigerant:industrial alcohol
