Scope of standard

1.1 This test method covers a single laboratory procedure that can be used to develop data from which either the relative abrasivity of any slurry (Miller Number) or the response of different materials to the abrasivity of different slurries (SAR Number), can be determined. 1.2 The test data obtained by this procedure are used to calculate either a number related to the rate of mass loss of duplicate standard-shaped 27% chromium iron wear blocks when run for a period of time in the slurry of interest (Miller Number), or to calculate a number related to the rate of mass loss (converted to volume loss) of duplicate standard-shaped specimens of any material of interest when run for a period of time in any slurry of interest (SAR Number). 1.3 The requirement for a finished flat wearing surface on the test specimen for a SAR Number test may preclude application of the procedure where thin (0.051 to 0.127-mm), hard, wear-resistant coatings will not allow for surface finishing. The 6 hours total duration of the SAR Number Test may not allow establishment of a consistent rate-of-mass-loss of the unfinished surface. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the respionsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
