K93600 Multispecimen Tester
The Multispecimen Tester is used to test the friction and wear characteristics of a wide variety of materials such as coatings, lubricants, plastics, metals, polymers, ceramics, and composites under various interface conditions including single, multiple, sliding, and rolling contact as well as point, line, and area contact. The test is performed by mounting a test specimen into the spindle and rotating it against a counter-face test specimen which is held stationary. The spindle rotation speed, normal load, and interface temperature can be adjusted in accordance with published ASTM standards. These operating parameters along with the resultant frictional force can be monitored using TriboDATA, the supplied Windows-based Data Acquisition Software. Specimen holders are designed for standard test configurations; optional custom designed holders for customer specific applications are also available. The test configurations are easily interchanged, allowing for a wide variety of testing applications within a single unit. The standard test configurations are shown in the configurations table.
