Method and apparatus for testing of the unobstructed relaxation maintaining of an upset viscoelastic foam

摘要

Device for testing of the unobstructed relaxation maintaining of an upset viscoelastic foam, characterized in that the apparatus comprises a unguided, light, rigid pressure plate (12), switchable holding elements (11) and at least one contactless distance sensor (4), wherein the unguided, light, which is of rigid printing plate by the switchable holding elements held in place and is released and the distance between the printing plate and the contactless distance sensor can be detected.
