This compression test jig is specifically designed to test rubber foam and urethane foam specimens that are molded, cored from a larger sheet, or shaped, for example, having a dimpled pattern.
The compression test jig for foam specimens consists of a 200 mm (7.9 in) diameter upper compression plate and a larger 400 mm (15.7 in) by 400 mm lower support plate. The lower plate contains holes 6.5 mm (0.26 in) in diameter, spaced 20 mm (0.79 in) apart. The perforations are designed to allow air to escape from the foam during testing.
Common tests applicable to rubber foam and urethane foam include compression to a specified deflection or force, where the resulting force or deflection, respectively, are measured, and maintenance of a constant deflection with measurement of recovery.
Compression test kits for foam specimens are available in certain regions. In addition to the compression test jig, these kits include a compression and bending loading jig. Please contact your local Shimadzu representative for details.
This compression test jig for foam specimens cannot be installed on universal testers with safety covers attached.
