ASTM G65 Measuring Abrasion Using the Dry Sand/Rubber Wheel Apparatus
The ASTM G65 test method specifies laboratory procedures for assessing the resistance of metallic materials to scratching abrasion using the dry sand/rubber wheel test. The goal of this test procedure is to generate data that will consistently rank materials in terms of their resistance to scratching abrasion under a certain set of conditions. Abrasion test results are presented as volume loss in cubic millimeters for the specific test protocol described. Materials with stronger abrasion resistance will have less volume loss. Volume loss data received from test materials whose lifetimes are unknown in a certain abrasive environment can, however, be compared to test data collected from a material whose life is known in that environment. If abrasion is the primary cause of material deterioration, the comparison will provide a general estimate of their value.

ASTM G65Introduction
The ASTM G65 test procedure uses dry sand/rubber wheel equipment to measure abrasion. For numerous industries, such as manufacturing, construction, and mining, abrasive wear is a serious problem. Wear can harm machinery and equipment, increasing maintenance expenses, and decreasing production in the end.
The ASTM G65 test technique is extensively employed to evaluate a material’s ability to withstand abrasive wear by mimicking the abrasive conditions that the material may encounter in different industries. This test method is important in raw material testing. This test method yields test data that can be used to assess the impact of various processing or treatment conditions on material wear resistance or to compare the abrasion resistance of various materials. The test compares wear-resistant materials by their volume loss in cubic millimeters, with materials of higher wear resistance showing lower volume loss. MaTestLab is a top material testing services aggregator in the United States and Canada.

ASTM G65 Test Method
The ASTM G65 test method involves using a dry sand/rubber wheel apparatus to apply a controlled abrasion to a test specimen. The test specimen is typically a flat or curved surface that is mounted onto a rotating wheel that is connected to the dry sand/rubber wheel apparatus. The apparatus is designed to rotate the test specimen at a constant speed while a specified amount of dry silica sand is fed onto the surface of the specimen.
The test procedure consists of two steps. The test is stopped after a specified duration or when the specimen has worn to a predetermined level. The weight loss of the test specimen is then measured, and the test results are calculated.
Step 1
The test specimen is weighed and installed on the test wheel in the first step.
Step 2
In the second step, the test specimen is subjected to the abrasive action of the dry sand/rubber wheel apparatus.
ASTM G65 Equipment and Sample Preparation
Specimen Details
ASTM G65 test method is applicable to a wide range of materials, including metals, ceramics, plastics, and composites.
Specimen dimensions
Specimens are prepared with flat or curved surfaces that are free of surface defects, scratches, and other damage. The acceptable specimens for ASTM G65 are typically rectangular in shape, with a thickness of 3 to 25 mm and a surface area of 25 to 100 cm².
Specimen preparation
Specimens are prepared such that they have flat or curved surfaces that are free of surface defects, scratches, and other surface damage.
ASTM G65 Resultsand Interpretation
The ASTM G65 test method provides several measures of material abrasion resistance, including weight loss, volume loss, and wear rate. The test results can be used to compare different materials’ abrasion resistance or evaluate the effect of different processing or treatment conditions on material wear resistance.
Tests Related to ASTM G65
ASTM G65 is similar to other standard test methods for measuring abrasion resistance, such as ASTM G105 and ASTM G132. ASTM G105 uses a taber abrasion machine to apply a controlled amount of abrasion to a test specimen, while ASTM G132 uses a rotating-cylinder apparatus to simulate abrasive wear. These test methods are often used in combination with ASTM G65 to provide a more comprehensive evaluation of material abrasion resistance. ASTM G65 is also related to ASTM D3170 chipping resistance of coatings.
Use of ASTM G65 in Various Industries
This test is of great interest to companies working in industries such as automotive, oil and gas, agriculture, aerospace, mining, and construction since material and coating durability is of utmost importance for the adequate functioning and safety of their products and operations.
Materials Commonly Tested with ASTM G65
This standard tests various materials among these different types, such as steel, cast iron, alloys, hard facing materials, wear-resistant coatings, and ceramics. These environments include carbon, stainless, HSLA, tool steels, and weld overlays.
Common Challenges and Troubleshooting in ASTM G65 Testing
Some of the challenging issues include inconsistency in sand flow, degradation of the hardness of the wheel, problems with mounting the sample, and errors in data interpretation. Accurate results can only be received if calibration and inspection is carried out, proper sample mounting is conducted, adherent materials, controlled conditions, and calculations are double-checked.
Sand/Rubber Wheel Abrasion Technique Process and Data Collection
This standard method uses a dry sand/rubber wheel abrasion technique to determine the material’s resistance to wear. It involves preparing a specimen, mounting the specimen against a rotating wheel, using dry silica sand as the abrasive material, and testing at certain conditions such as rotation speed and pressure, thus providing quantitative data for the abrasion resistance of a material.
Importance of ASTM G65
It is a powerful test method to study abrasion resistance that provides predictive wear performance, cost efficiency, consistency, and comparability. It aids in the proper selection of materials, reduces maintenance costs, and ensures safety in industries such as aerospace and mining.
