A test fixture which permits critical parts to be tested prior to permanently mounting the critical parts onto a larger assembly is described. The test fixture comprises a base member 1 having at least one mandrel 2 for holding the critical part 3 to be tested. The mandrel 2 comprises a chuck portion 4 and a spring-loaded shaft 5 which is terminated in a tapered end part 7. The chuck portion 4 is expandable, and the expansion or contraction is controlled by movement up or down (as shown by arrow 6) of shaft 5. When shaft 5 is moved up, end part 7 permits the chuck member to contract so that part 3 to be tested can be inserted over the mandrel. When shaft 5 is then moved down, chuck member 4 expands to hold the part 3 firmly in position so that testing can be accomplished.
