Under what circumstances does the taber wear tester need to be calibrated and how to calibrate it?

Taber Abrasion Tester is a commonly used testing equipment for testing the wear resistance of materials. Due to long-term use and other factors, the Taber abrasion tester may have deviations or errors, so regular calibration is required to ensure the accuracy and reliability of the test results. This article will introduce the situation and method of Taber abrasion tester calibration.

1. Calibration of Taber Abrasion Tester

1. Initial calibration is required after installation of new equipment. This is the basis for ensuring the accuracy of the equipment, and only after the initial calibration of the equipment can subsequent testing work be carried out.

2. Periodic calibration. Depending on the frequency of use of the equipment and the requirements of the test results, periodic calibration is required. Calibration is recommended every six months to one year to ensure the accuracy of test results.

3. Calibration is required after equipment repair or parts replacement. Calibration is required if the equipment is found to be biased or inaccurate, or if parts need to be replaced. This ensures that the device remains accurate after repairs or replacement parts.

2. Calibration method of Taber abrasion tester

The calibration of the Taber wear tester requires the calibration of two parts, the calibration disc and the wear head. The following are the specific steps of Taber wear tester calibration:

1. Calibration of the calibration disk

(1) Install the calibration disk on the equipment, and install the disk on the equipment according to the requirements of the equipment manual.

(2) Rotate the calibration disk to the specified speed, and use the Taber calibration tool to calibrate the disk. The calibration tool is generally a standard wrench that adjusts the height of the disc until the tip of the calibration tool contacts the disc.

(3) After the calibration is completed, remove the calibration tool, rotate the disk to different positions, and check whether the contact between the disk and the equipment is stable to determine whether the calibration is successful.

2. Calibration of the wear head

(1) Install the calibration wear head on the equipment, and install the wear head on the equipment according to the requirements of the equipment manual.

(2) Fix the calibration wear head on the test table and adjust the height so that the contact force between the wear head and the test sample meets the requirements.

(3) Rotate the calibration wear head to the specified speed for calibration. Use the calibration tool to adjust the height of the wear head until the wear head is in contact with the tip of the calibration tool, as required by the equipment instruction manual.

(4) After the calibration is completed, remove the calibration tool, rotate the wear head to different positions, and check whether the contact between the wear head and the test sample is stable to determine whether the calibration is successful.

3. Precautions for Calibration of Taber Abrasion Tester

1. Before calibration, the equipment needs to be cleaned to ensure the accuracy of the test results.

2. When performing calibration, it is necessary to operate in accordance with the requirements of the equipment manual to avoid operational errors.

3. Calibration tools need to be calibrated before use to ensure the accuracy of the calibration tools.

4. During the calibration process, it is necessary to pay attention to the height adjustment of the calibration disc and the wear head to ensure the precision and accuracy of the calibration.

5. After the calibration is completed, the calibration results need to be recorded for subsequent reference and comparison.

6. If there is a deviation or error in the equipment, it needs to be calibrated in time to ensure the accuracy and reliability of the test results.

In conclusion, Taber abrasion tester calibration is a necessary step to ensure accurate and reliable test results. When performing calibration, it is necessary to operate in accordance with the requirements of the equipment manual and pay attention to details to ensure the precision and accuracy of the calibration. In addition, regular calibration is also one of the important measures to ensure the long-term use and maintenance of equipment.
