Standard Test Method for
Abrasion Resistance of Dimension Stone Subjected to Foot
Traffic Using a Rotary Platform Abraser
This standard is issued under the fixed designation C1353/C1353M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
ε NOTE—In 6.1.1, the value in the last sentence was corrected editorially from 0.008 in. [0.02 mm] to 0.008 in. [0.2 mm]
