ASTM G132-96 (2013) – Two-body abrasive wear test

Figure 1: Principle of the sandpaper method

Two-body abrasive wear testing according to ASTM G132-96 (2013)

The tests described in ASTM G132-96 (2013) are used to determine two-body abrasive wear. In this test, the abrasive particles are fixed to a substrate, over which the specimen is then dragged. At ISAF, the sandpaper method is used as an example.

 

Sandpaper method (pin-on-table)

In the sandpaper method, the rotating test specimen is guided in a meandering pattern across a sheet of sandpaper with a defined contact force (Figure 2). Here, too, the motion ensures that new abrasive particles are constantly brought into contact with the specimen.
