What is the DIN abrasion test procedure?

The DIN Wear Test Procedure is a standard test method for evaluating the wear resistance of materials and is based on the specifications of the German Industrial Standards Organization (DIN). Specifically, DIN wear test procedures can be implemented in different standards, such as DIN 53 786, DIN 50 115 and DIN 53 719, depending on the required test conditions and purpose.

DIN 53 786 is a common wear test procedure used to measure the wear properties of materials under specific conditions. The test method is performed by applying a certain amount of force and friction in a testing machine so that the specimen interacts with a friction body and is accurately measured and recorded. Depending on the purpose and needs of the test, the friction body may be a steel ball, sandpaper, roller or other applicable material.

DIN 50 115 is another common wear test procedure that is typically used to measure the abrasion resistance of materials. It uses a rotating disk or roller in contact with a specimen to apply a certain amount of force and friction to measure the amount of wear of the specimen over a certain period of time or conditions.

DIN 53 719 is a standardized test procedure used to evaluate the abrasion resistance of rubber and elastomeric materials. It evaluates the abrasion resistance of a material by applying a force and rotary motion in a testing machine, using a standardized specimen (e.g., a roller or other tool), and measuring the loss of mass or the amount of wear on the specimen.

The DIN wear test procedures listed above are based on the actual test operations, which may vary, and the following are the test steps of a common DIN wear test procedure:

1. Prepare the specimen: the material is cut or fabricated into specimens of standard shape and size.

2. Prepare test equipment: Select the appropriate test equipment and test conditions according to the test standard. For example, for the DIN 53 786 test method, a testing machine and standard steel balls are required. 3.

3. Mounting the specimen: The specimen is mounted in the testing machine and the test is started by applying force and friction according to the requirements of the standard.

4. Measurement data: According to the test requirements, the wear amount and friction coefficient of the specimen during the test are recorded by the sensor attached to the testing machine or by external measuring instruments.

5. Analysis and report: According to the test results, analyze the wear characteristics and performance of the material, and report the test results to the customer or user. The test report should contain detailed information on the test conditions, test methods and test results.

It should be noted that different DIN wear test procedures may target different types of materials, test conditions and purposes, so when selecting a test method, the corresponding standards and specifications should be read carefully to ensure the accuracy, reliability and comparability of the test. In addition, the necessary safety measures should be in place before the test to prevent accidents from occurring.

Overall, DIN wear test procedures use specific devices and measurement methods according to different test standards and requirements in order to accurately assess the wear resistance of materials under specific conditions.
