From the results it is clear that there is a correlation between the dead load and the micro IRHD instruments.
Generally, the micro instruments can be used for testing both micro and macro samples, while the macro instruments (IRHD dead load and type A durometer) are better for macro samples.
Flatter curves are produced with the IRHD dead load, micro and the type A durometer instruments when testing curved samples, implying that there is less critical dependence on accurate sample positioning with these.
