Compression stress relaxation is being increasingly adopted by aerospace, automotive and construction industries to characterise elastomeric seals.
The Wallace Compression Set Apparatus (Constant Strain) - C3/C4
The set is the residual strain in a rubber test piece after it has been subjected to stress for a given time and then allowed to recover for a given time, the temperature being substantially constant during the test.
The Wallace Compression Stress Relaxometer Mk IV - C11
The Compression Stress Relaxometer is widely used in the aerospace, automotive and construction industries for the accurate testing of elastomeric seals.
