ABSTRACT:
A device for testing a sample of foam material and a method for making such a test include compressing the sample repetitively by means of a dropped weight. The weight includes a plunger which moves vertically in a sliding bearing arrangement. The plunger is raised by a solenoid and allowed to drop so as to compress the sample only by a predetermined percentage of its original diameter. The force applied to the sample is monitored during this compression operation and the ratios of forces between the initial force measurement and the force measurement made during subsequent drops provides a quantitative indication of the weakness in the foam cell structure.
