Jig For Compression-Relaxation Tests Of Plastics

Richard M. Shelley, James A. Daniel, Ralph M. Tapphorn

Abstract

Improved jig facilitates tests of long-term compression-relaxation properties of plastics. Holds specimen in compression when removed from compression-testing machine, yet allows compression force on specimen to be measured when on machine. Useful in quantifying some of time-dependent properties of polymers, in investigations of effects of aging, and in ascertaining service lifetimes of polymeric components.
