1.1 This test method covers a laboratory procedure to determine the relative gouging abrasion resistance of materials. Materials homogeneous in structure and properties are the most appropriate test materials; however, surface-treated and composite materials can also be tested. The test involves a small laboratory jaw crusher that crushes presized hard rock materials, such as a hard morainal gravel, or some other crushable substance.

1.2 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. (See 8.1 on Safety Precautions.)

1.3 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.


5.1 A number of types of jaw crushers have been used for laboratory abrasion tests, see Refs (1-5)4 and a limited amount of data has been published (6-10). With emphasis on the crusher described in Section 6, this test method ranks materials and also indicates differences in wear life for that type of abrasion defined as gouging abrasion, as is found in crushing equipment and in many mining and earthmoving applications. This test method is considered useful for research and development purposes, but not to specify universal wear ratios, since the wear ranking and severity of wear may change dramatically with a change of the characteristics (chemistry, shape, angularity, etc.) of the crushed material or type of machinery.
