Stress relaxation tester. (Suppliers Showcase: Instruments).


The C11 Mk IV compression stress relaxometer is said to feature simple measurement of stress relaxation Stress relaxation describes how polymers relieve stress under constant strain. Because they are viscoelastic, polymers behave in a nonlinear, non-Hookean fashion.[1] , a non-continuous method so that only one instrument is required for testing any number of jigs, forces of up to 2.2 kN can be measured, and a limiting force value to protect load cell and jig jig, dance of English origin that is performed also in Ireland and Scotland. It is usually a lively dance, performed by one or more persons, with quick and irregular steps. When the jig was introduced to the United States, it was often danced in minstrel shows. . The jigs can be used for testing samples in different environments. Different size samples and different compression ratios compression ratio

Degree to which the fuel mixture in an internal-combustion engine is compressed before ignition. It is defined as the volume of the combustion chamber with the piston farthest out divided by the volume with the piston in the full-compression position (
 can be applied. The jigs are suitable for testing o-rings, and samples are said to be easily loaded into the jigs. Optional PC software features data collection, analysis and storage, the ability to adjust instrument parameters, data tabulated or graphed by reaction force, stress relaxation or force retention, statistical analysis and storage of jig data, including operator identification. Stress relaxation is said to be an important measurement used primarily in the aerospace, automotive and construction industries for the effective and accurate testing of elastomeric seals, joints and gaskets, according to according to
