FYI ASTM D746 /ISO 974 Low Temperature Rubber Brittleness point temperature tester DW1480
FYI ASTM D746 /ISO 974 Low Temperature Rubber Brittleness point temperature tester DW1480
Application
DW1480 FYI ASTM D746 /ISO 974 Low Temperature Rubber Brittleness point temperature tester DW1480 is used to determine the brittleness temperature of plastics and elastomers by impact testing and evaluate their usage property under the condition of low temperature. It is also used to determine the brittleness temperature of different rubbers or vulcanized rubbers of different ingredients and assess their properties under the condition of low temperature. Specimens are fixed to a specimen holder with a torque wrench. The specimen holder is immersed in a cooling bath containing a heat-transfer medium. The specimens are struck at a specified linear speed and then examined. The brittleness temperature is defined as the temperature at which 50% of specimens fail.
