How to do the period verification of the friction coefficient testing machine?

The verification during the friction coefficient tester usually includes the following steps: 1. Verify whether the instrument is in a normal state: Before the verification, it is necessary to check various parameters of the friction coefficient testing machine, such as friction force, slider speed, temperature, etc., to ensure that it is in a normal state. Standard friction meters or other calibrated instruments can be used for verification. 2. Run standard samples: In order to verify the accuracy of the friction coefficient testing machine, standard samples need to be used for testing. These samples should have known friction coefficient values and be similar to the range of friction coefficients of the tested materials.After running the standard sample, the difference between the test results and the standard value should be compared to determine the accuracy of the test machine. 3. Running quality control samples: In order to evaluate the precision and stability of the friction coefficient tester, it is necessary to use quality control samples for testing. These samples should have a friction coefficient value similar to the measured material, and be tested at different times and in different instruments. By testing the quality control samples, the precision and stability of the testing machine can be evaluated. 4. Check the maintenance records: During the verification period, it is necessary to check the maintenance records of the friction coefficient testing machine, including calibration records, cleaning records, maintenance records, etc. If the instrument is found to be abnormal or improperly maintained, it should be repaired or calibrated in time. 5. Record the verification results: in the completion of the friction coefficient test machineAfter the verification period, the verification results shall be recorded in the relevant documents, including the verification date, instrument status, verification results, etc. These records can be used to track the performance and history of the instrument and trace it back when needed. It should be noted that during the verification, the use of words such as exaggeration, political sensitivity, medical diseases or brand trademarks should be avoided, and the verification process and results should be described in objective and concise language as much as possible.
