ABSTRACT:
A holder for a corrugated paperboard test specimen is designed to orient the specimen in a vertical plane so that the specimen can be subjected to an edgewise compression test. The holder includes upper and lower clamps that grip the upper and lower surfaces of the specimen, leaving an intermediate section of the specimen unsupported; the specimen will experience a buckling action in the unsupported section as a response to progressively increased vertical loads. Each clamp includes a spring-biased clamping pad that can be retracted manually to permit insertion of a test specimen into the clamping space.
