PAM-Comfort Foam (Dynamic)

Test ID



Testing is performed on the base foam material to obtain the non-linear viscoelastic response of the material. Tests are performed in a compressive mode on a DMA. The samples are precycled to 80% strain three times and allowed to recover for at least 5 minutes. Samples are then compressed to a static strain of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65 70, 75, 80 % (or until load cell has reached its limit) and a dynamic strain of less than 1% at each strain level. The frequency at each level tested is 0.5 %. E’, E”, and tan delta are reported versus the imposed strains as well a gain and phase angle.

Included Tests

1x M-600 DMA - Tensile/Compressive ( 0.1-100 Hz)



: 3 prisms



Testing is performed to generate data to be used in the PAM Comfort FOAM_VIBR_01 or 02 material cards. Dynamic testing is performed to simulate the behavior of the foam material when subjected to an initial with dynamic vibrations. This TestPak may be combined with other PAM Comfort TestPaks to simulate static behavior of seat systems.
