14 Jan One of the more common American Society for Testing and Materials (ASTM) tests to evaluate abrasive wear resistance is the ASTM G 3 Jul The graph below presents the results of abrasion resistance tests performed in accordance with the ASTM G65 standard – Procedures A and B. ASTM G65 – 04() Standard Test Method for Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus. Background: Abrasive wear of industrial.

In order to attain uniformity among laboratories, it is the intent of this test method to require that volume loss due to abrasion be reported only in the metric system as cubic millimetres.
Procedure B should be used when the volume—loss values developed by Procedure A exceeds mm 3.

This standard does not purport to address the safety concerns, if any, associated with its use. The value of the practice lies in predicting the relative ranking of various materials of construction in an abrasive environment.
Test Conditions Tested for revolutions at a load of 30 lb. Materials of higher abrasion resistance will have a lower volume loss. It may be used for highly abrasive resistant materials but is particularly useful in the ranking of medium- and low-abrasive-resistant materials. Materials of higher abrasion resistance will have a lower volume loss.
Friction wheel test ASTM G65-16 (dry sand/rubber wheel test)
Its value lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Hardness testing h65, microscopes and digital imaging at Kondex.

It is also used in ranking materials of a specific generic type or materials which would be very close in the volume loss rates as developed by Procedure A. The five lots of the abrasive, purchased from U.

Low-Stress Abrasion Abrasive wear occurs when hard particles are compressed with normal pressure against the surface of a metal, causing material removal. It is also used in ranking materials of a specific generic type or materials which would be very close in the volume loss rates as developed by Procedure A.
It may be used for highly abrasive resistant materials but is particularly useful in the ranking of medium- and low-abrasive-resistant materials. Grinding with a surface grinder can be a controlled form of low stress abrasion.
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.
Sample preparation equipment in Kondex metallurgical lab. Volume loss data obtained from test materials whose lives are unknown in a specific b65 environment may, however, be compared with test data obtained from a material whose life is known in the same environment.

The operating forces must be low enough to prevent crushing the abradant. These capabilities allow us to verify mechanical properties and microstructures of materials and coatings, analyze heat treatments, and perform failure analyses and competitive analyses. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of asgm limitations prior to use. Low stress abrasion rates are directly proportional to the sliding distance and the load on the particles or protuberances.
It is the intent of this test method to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions. It also provides hard data to an otherwise subjective performance indicator that can satm used for marketing and sales. Wear VolumeIssues 9—1029 JulyPages It is particularly useful in ranking materials of medium to extreme abrasion resistance.
Since the practice does not attempt to duplicate all of the process conditions abrasive size, shape, pressure, impact, or corrosive elementsit should not be used to predict the exact resistance of a given material in a specific environment.
Procedure B should be used when the volume-loss values developed by Procedure A exceeds mm 3.
