Pendula Hardness Tester calibrating steps

The pendulum Hardness Tester, also known as "pendulum Hardness Tester", is a device used to measure the hardness of materials. The instrument swings the pendulum from a fixed point to hit the sample, and the sample is clamped on the machine base. Hardness is measured by the amount of energy transferred to the specimen when the pendulum strikes.

Pendulum Hardness Testers are primarily used to test coatings and paints to determine their scratch and abrasion resistance. The test involves measuring the height of the sample after the swing of the pendulum hits it and comparing it to a reference material. The difference in height indicates the hardness of the sample and can be used to assess its durability and suitability for its intended application.

Calibration steps

Calibrating a pendulum durometer is important to ensure accurate and consistent hardness measurements. The following are the general steps for calibrating a pendulum Hardness Tester:

    Set up the test area: Place the pendulum Tester on a level surface, away from any sources of vibration or drafts.

    Inspect the pendulum: Make sure the pendulum is in good condition and not damaged or worn. Check the calibration marks on the pendulum to make sure they are visible and accurate.

    Prepare reference material: Select a reference material with a known hardness value and similar composition to the material that will be tested. The reference material should be placed on the base of the durometer.

    Adjust Calibration: Adjust the calibration of the Hardness Tester to match the known hardness value of the reference material. This is usually done by adjusting the position of the pendulum or a calibration weight on the pendulum.

    Test the reference material: Swing the pendulum and tap the reference material several times, measuring how far the pendulum swings after each tap. Calculates the average of height measurements.

    Compare Results: Compare the average height measurement of the reference material to the material's known hardness value. Adjust the calibration of the Hardness Tester as needed to ensure accurate measurements.

    Test sample material: After the Hardness Tester is calibrated, it can be used to test the hardness of the sample material.

North and South Chao reminds you: Depending on the specific model and manufacturer of the pendulum Hardness Tester, the calibration process may be slightly different. Always refer to the manufacturer's instructions for specific calibration procedures.
