Compression Set Fixture test result would help you to know the properties of elastomers and can be a reference for your elastomer selection guide to choose low compression set rubber, elastomers. Know more about compression set test by this article.

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.
