[FIGURE 2 OMITTED] Creep measurements can be used to measure indentation hardness in terms of force/unit indentation in a manner similar to Tukon, Pfund, and Vickers hardness.
The Brinell indentation hardness test was performed with a 1 mm diameter steel ball, with loads 49 and 98 N and loading time 30 sec: --HB (1 mm diameter steel ball and load 49 N) to test materials 1--2 and 4--7 (Table 5); --HB 1/10 (1 mm diameter steel ball and load 98 N) to test material 3 (because the load 49 N did not make observable indentation on the measured surface and thus the load 98 N was used).
This brochure contains durometers and durometer systems that cover the entire spectrum of indentation hardness testing of rubber-like materials.
