ASTM C241/C241M-15
(Test Method)Standard Test Method for Abrasion Resistance of Stone Subjected to Foot Traffic
Standard Test Method for Abrasion Resistance of Stone Subjected to Foot Traffic
SIGNIFICANCE AND USE
4.1 This test method is useful in indicating the differences in abrasion resistance between the various building stones. This test method also provides one element in comparing stones of the same type.
SCOPE
1.1 This test method covers the determination of the abrasion resistance of all types of stones for floors, steps, and similar uses where the wear is caused by the abrasion of foot traffic.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.2.1 Exception—The formula for calculation of the result of this test method relies on the use of SI units; all measurements of weight in this test method shall be recorded in SI units. See 9.1 and 10.1.
1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

4. Significance and Use
4.1 This test method is useful in indicating the differences in abrasion resistance between the various building stones. This test
method also provides one element in comparing stones of the same type.
5. Apparatus
5.1 The abrasion testing apparatus shown in Fig. 1 shall be used. This apparatus consists essentially of a power-driven grinding
lap, A, 10 in. [250 mm] in diameter, which is revolved at 45 rpm; three specimen holders, B, with superimposed weights; gears,
C, for revolving the specimen; and a means of feeding abrasive at a constant rate to the lap. The guide rings, D, are clamped in
position slightly above the specimen holders, and the 2000 g weight bearing on the specimen is the combined weight of the
specimen holder, vertical shaft above with the attached spur gear, and a weight hopper, E, containing additional adjustment
weights. The frame, F, carrying the guide rings is adjustable vertically to accommodate different specimen thicknesses. Gears, C,
are adjusted on the shafts for each specimen thickness, so that they are slightly above the plate, G, throughout the test.
6. Sampling
6.1 The sample may be selected by the purchaser or his authorized agent but shall represent the average quality of the type or
grade of stone under consideration. It shall be of sufficient size to permit the preparation of at least three test specimens, and one
face should have the finish to be exposed to traffic. The sample preferably should be 1 in. [25 mm] thick and 8 in. [200 mm] square.
