A support jig for use with a testing machine applying loads, the support jig includes a frame and a pair of spaced apart supports joined to the frame to provide an alignment axis. Each support is configured to releasably hold a test specimen holder on the alignment axis in a fixed spatial relationship with ends of the test specimen holders mountable to the test machine facing in opposite directions. A test specimen support is located between the holders holds the test specimen on the alignment axis so that the holders can be attached to the test specimen. The support jig allows the holders to be easily and correctly attached to the test specimen so as to maintain alignment of the holders and the test specimen on the alignment axis. The support jig also maintains the fixed spatial relationship of the holders and test specimen while the holders are mounted to the test machine.

Support jig with improved support grips

A test specimen holder includes a specimen engaging portion operable to selectively engage and hold a test specimen. The test specimen holder includes a first shield disposed around the specimen engaging portion wherein a first gap is formed between the shield and the specimen engaging portion to remove heat from the specimen engaging portion.

Test specimen holder for high temperature environments

A test specimen holder includes at least one pair of wedges, a plurality of pistons and a tie bar connected to each of the pistons. A single cylinder body is operable with each of the pistons and the wedges. The cylinder body is adapted to urge the wedges together with relative movement of the cylinder body with respect to the pistons.
