ABSTRACT:
A testing apparatus comprising two platens one of which is a self-aligning pecimen contacting platen which includes an upper portion comprising a first member which contacts the specimen and a second member which is spaced from a base by a plurality of balls. The first and second members are movable relative to each other to pivot the specimen into proper alignment between the platens when the specimen is subjected to compression. The plurality of balls are juxtaposed between and engage the second member of the upper portion and the base and serve to support the upper portion for lateral and rotational movement relative to the base to facilitate alignment.
