| Significance and Use | ||||||||
|
5.1?This test method is useful in indicating the differences in abrasion resistance between various building stones. This test method also provides one element in comparing stones of the same type. Note 1:?Test Method C1353/C1353M is an alternative method to
evaluate abrasion resistance for stone subjected to foot traffic,
but is not applicable for hard and coarse-grained stones such as
granite. Preliminary assessments by Subcommittee C18.03 indicate it
results in similar Ha values as established by
this method.

| 1. Scope | ||||||||
|
1.1?This test method covers the determination of abrasion resistance of all types of stones for floors, steps, and similar uses where the wear is caused by 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?ExceptionThe 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 10.1 and 11.1. 1.3?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
