Measuring Compression Set of Solid Elastomers. Most compression set testing follows ASTM D395, Test Method B. Solid elastomer specimens 0.25″ thick x 0.52″ diameter are compressed to 0.177″ thick using a device as diagrammed, for 22 to 70 hour periods at elevated temperature in an air circulating oven. Compression set represents the percent of deflection that did not return.ASTM D575 – Standard Test Methods for Rubber Properties in Compression. While intended for rubber, these test methods can be adapted for certain cellular materials, and IFD tests may be conducted using these guidelines. ASTM D1056 – Standard Specification for Flexible Cellular Materials – Sponge or Expanded Rubber. This specification .Indentation Force Deflection (IFD) tests measure firmness of flexible polyurethane foam cushions. High IFD test results imply increased hardness. Low IFD results indicate soft foam products. Note that the term IFD, or indentation force deflection, is interchangeable with ILD, or indentation load deflection. The IFD test is one of multiple test methods that are all defined in .
Understanding Compression Tests
For most applications a range between 5% to 15% deflection is acceptable. However, applications with rapid continuous deflection may need to be limited to lower deflection percentages. We recommend not exceeding 25% deflection regardless of the application.
The type can be open or closed cell type foam. The class has to do with it oil and temperature resistance. Finally, the grade rating is determined by the compression deflection given in PSI at 25% deflection. Unlike ASTM D3574, the sample for compression deflection testing for D1056 is much smaller. Solution: What is compression set? – Compression set of rubber materials expresses how much a material does NOT rebound after being compressed for a period of time at a specific temperature. The sample is released and measured, the results of the test (ASTM D395 ) are expressed in a percentage. Often this is referred to the memory of the foam.Performance tests are run using standard test procedures. The values presented are typical values and should not be used for specification purposes.
