Friction Assessment and Screening Test (FAST)
- Lab E36
Friction Assessment and Screening Test (FAST) The
FAST machine was developed at Ford Motor Company in the early 1960s. It
became a standard test for automotive brake materials for a period of
time. It provides the ability to make direct comparisons between
differing brake materials, batch-to-batch comparisons, or within-batch
comparisons. The test itself is a drag test at 7 m/s of a 0.5-inch
square brake pad sample that lasts 90 minutes. The machine may be run
using constant force or constant torque modes.
