1. Unuo ASTM D395 Compression Set Fixture Features

Warm Tip: please pay attention to sample hardness. Choose the suitable compression set method and steel spacer for the compression set test fixture.

2. Rubber Compression Calculation

CB=[(to-ti)/(to-tn)]*100 (the test result would be expressed in %)

  • CB=compression set (ASTM D395 method B) expressed as % of the original deflection.
  • To=original thickness of specimen
  • Ti=final thickness of specimen
  • Tn=thickness of the spacer bar used.

Warm tip: for your understanding compression set results, the lower % of the test result, the better your sample resists constant deflection.

3. Other needed equipment for compression set test

  • Environment Chamber
  • Aging Oven
  • Thickness Gauge
  • Hardness Tester

*Above lab testing machines are available from Unuo Instruments.
