Compressive Testing

Compressive testing is a very common testing method.  It may be used to measure the compressibility of a material and the recovery of a material that has been compressed to a load and held over a time period.  Compressive tests are used to determine the material behavior under a load.  The maximum stress a material can sustain over a period under a load (constant or progressive) is determined.  

Compressive testing is often done to a break or to a limit.  When the test is performed to a break (rupture), a break detector is used.  When the test is performed to a limit, either a load limit or deflection limit is used.

Common results available from Chatillon system for compressive testing are:

• Load at Rupture
• Deflection at Rupture
• Work at Rupture
• Maximum Load
• Deflection at Maximum Load
• Work at Maximum Load
• Stiffness
• Chord Slope
• Offset Yield
• Stress
• Strain

Common industry standards for determining compressive strength are:
- ASTM C-773
- ASTM D-575
- ASTM D-623
- ASTM D-695
- ASTM D-395
- ASTM E-9
- ASTM E-209
- ASTM F-36
