Compression Test Jig for Foam Rubber Specimens
Foam Hardness Measurement
The following shows the test control and data processing for obtaining foam hardness.
Control pattern
Data processing
- Hardness of specimen (specimen thickness at initial test force value)
- Hardness at 25 %, 40 % and 65 % of specimen thickness is obtained.
Compression Deflection
The following shows measurement of the compression deflection coefficient and hysteresis loss ratio of foam.
Control pattern
Data processing
- Compression deflection coefficient (S65/S25)
- Hysteresis loss (area enclosed by reciprocation/area of forward feed × 100)
