The Zwick 3106 hardness tester can be used for all hardness tests involving indentation measurement and provides values for research, development, quality control and acceptance/rejection according to specification.

One particular application is ball indentation hardness of plastics to ISO 2039-1, for which a defined test load is pressed into the surface of the specimen. The indentation depth measured under load has a mathematical relationship to the recorded hardness in N/mm².

Additional standards for which the Zwick 3106 can be used:

• ASTM D 785: Rockwell (plastics)
• ISO 6508: Rockwell (metals)
• DIN 1168-2: hardness of plaster
• DIN 1996: indentation test method for asphalt
• DIN 51917: Rockwell (carbon materials)
• EN 433: residual indentation on elastic floor coverings
