ASTM C808-75(2005)

1.1 This guideline covers the following areas for reporting friction and wear test results of manufactured carbon and graphite bearing and seal materials:

1.1.1 Description of test device and techniques (Table 1).

1.1.2 Description of carbon and graphite material test specimen (Table 2).

1.1.3 Description of mating member test specimen (Table 3).

1.1.4 Report of friction and wear test results (Table 4).

1.2 Many types of equipment and techniques will yield consistent data characterizing the friction and wear of carbon and graphite materials. However, the ranking of the materials by the various test methods used is not necessarily the same. This guideline is an initial effort to promote more complete description of the test methods, whatever they may be. It is the eventual intent to identify one or more specific standard test methods when sufficient information becomes available.
