RT-133 Rubber Compression Heat Generation Flexometer Testing Machine (ASTM-D623)
30 ~ 85 IRHD Vulcanized Rubber Flexometer Compression Heat Tester
This machine is used to test the compression heat generation and fatigue of vulcanized rubber with a hardness of less than 85 IRHD. It’s utilized for flexural testing (Heat Generation test) and fatigue testing in tensile, compression and shear modes to determine the heat generation on the surface and inside of the sample.
The machine applies a certain compression load to the specimen through an inert lever system, and a periodic high-frequency compression with a specified amplitude to the specimen through a transmission system to determine the compression fatigue temperature rise and fatigue life of the specimen in a certain period of time at room temperature or higher than room temperature.
By applying a specified compression load to the specimen and compressing the specimen periodically with a certain amplitude and frequency, the compression fatigue temperature rise, static compression deformation rate, dynamic compression deformation rate, permanent deformation, and fatigue life of the specimen within a certain period of time are measured.
