ASTM G65-16 Standard Test Method for Measuring Abrasion Using Dry Sand / Rubber Wheel Apparatus (Abrasion Test)

The ASTM G65-16 standard, developed by the American Testing and Materials Association (ASTM), defines test methods for determining the resistance of metallic materials to scratching abrasion by means of dry sand / rubber wheel test. The purpose of these test methods is to generate data that will reproducibly rank materials according to their resistance to scratch wear under a given set of conditions.

Abrasion test results, known as abrasion test in short, are reported as volume loss in cubic millimeters. Materials with higher wear resistance have lower volume loss. To ensure uniformity between laboratories, volume loss due to wear should only be reported in cubic millimeters in the metric system.

The ASTM G65-16 standard recommends five test methods deemed appropriate for certain grades of abrasion resistance or thickness of test material:

• Method A: This method ranks metallic materials on a wide scale of volume loss, from lowest to highest wear resistance. It is very useful in sorting materials with medium to extreme wear resistance.
• Method B: This method is a short-term form of method A and is used for materials with high resistance to abrasiveness. However, it is quite useful in sorting materials with medium and low abrasive resistance. Method B is used when the volume loss values ​​developed by method A exceed 100 mm3.
• Method C: This method is the short-term method of method A for use on thin coatings. is a form.
• Method D: This method is a lighter load form of method A and is particularly useful for grading materials with low wear resistance. It is also used to rank certain types of materials that are very close in volume loss rates developed by method A.
• Method E: This method is a short-term form of method B, which is useful for ranking materials with medium or low wear resistance.

Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of ASTM G65-16 standard, standard test (abrasion) to measure wear by using dry sand / rubber wheel apparatus. test) services.
