ASTM G65 Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus

Get Certified ASTM G65 Testing for Reliable Abrasion Resistance Evaluation 

ASTM G65 testing assesses the comparative abrasion resistance of metallic materials and coatings. It offers quantitative data for material comparison, quality control, and product development. Technicians perform tests in a controlled abrasive environment, and analysts determine and interpret volume loss. They use the results to assess material selection and specifications.

The standard consists of five procedures, A-E, varying in severity, length of time, or intended use. Results are presented as volume loss in cubic millimeters; the lower the figure, the more abrasion-resistant the material.

The scope of ASTM G65 includes: 

• Material: Metallic materials and applicable thin coatings evaluated using the appropriate procedure. 
• Objective: To compare the resistance to scratching abrasion of materials in controlled laboratory conditions. 
• Property measurement: Determine abrasive wear through the material’s volume loss. 
• Method: Rotating rubber wheel, dry abrasive sand, a specified load, and a controlled arrangement of the specimen. 
• Result: Report the volume loss in cubic millimeters (mm³) for the procedure selected. 
• Test Limitations: The test does not simulate all field conditions such as particle shape, impact, pressure, or corrosive exposure. 
• Environmental conditions: Set the apparatus parameters, abrasive feed, loading conditions,s and test procedure. 
• Applications: Test the wear resistance of metals, hardfacing materials, metal parts, and appropriate coatings in abrasive environments.

What are the materials that can be tested with ASTM G65? 

ASTM G65 is designed for metallic materials, such as metals, alloys, wear-resistant surfaces, and appropriate thin coatings, which are evaluated using the proper procedure. It can be used to compare resistance to scratching abrasion under controlled conditions, but the results are not necessarily predictive of service performance in all service conditions.

Why is ASTM G65 Important? 

Abrasive wear can affect component dimensions and surfaces and decrease the life of industrial machines. ASTM G65 offers a reproducible procedure for assessing material resistance to scratching abrasion and allows manufacturers to test material options before choosing materials for highly abrasive applications.

ASTM G65 Testing Process and Data Collection 

The first step in ASTM G65 testing is to determine the type of specimen and the testing procedure to be used based on the anticipated wear resistance and thickness. Technicians check the apparatus and ensure proper abrasive feed and loading system and document the specimen’s starting mass and other pertinent information. In testing, dry sand flows between a rotating rubber wheel and a specimen under certain conditions. Technicians measure the material loss of the specimen after the test, and the analysts calculate the volume loss according to the appropriate procedure. The report documents the selected procedure, material identification, recorded data, calculated volume loss in mm³, and any observations to facilitate comparison of materials.

Common Challenges and Troubleshooting 

Inconsistent abrasive feed, rubber wheel wear, incorrect loading, unsuitable specimen preparation, and inaccurate mass measurements can affect test repeatability. Technicians should check the apparatus, confirm the abrasive delivery system, adhere to the chosen procedure, and utilize appropriate measurement tools. Skilled personnel should also ensure that specimens are securely positioned and tested under the specified conditions. Before drawing conclusions, the analyst should review unusual volume-loss results to confirm no errors in equipment settings, specimen condition, abrasive characteristics, or calculation records.

• Laboratory reports present volume loss from abrasive wear in cubic millimeters (mm³), as required by the standard.
• Technicians record the material identification, specimen condition, selected procedure, and apparatus and test conditions.
• Analysts compare volume-loss results to determine the relative abrasion resistance of tested materials under the specified conditions.
• Analysts recognize that Procedure A, B, C, D, or E may have been used, as each procedure is designed for different wear-resistance levels or material thicknesses.
