LT-JJ34 Sponge Compression Permanent Deformation Testing Machine

Short Description:

The sponge compression permanent deformation test machine is mainly designed and manufactured according to the requirements of ISO1856 method A, sinking the sponge to 50% of the original thickness (or other) with the fixture, placing the thermostat with the temperature adjusted 70, until 22 hours before removing the compressor, removing the sample from the compressor and placing it for 30min, then the thickness is measured, and the deformation is calculated. The initial thickness of the sample varies from the final thickness of the sample after the specified recovery time after compression at the specified time and the specified temperature. The size of the difference is related to the initial thickness.
