Scope

Main technical content: 7.1 Calibration of the length of cold bending cores: Use a steel ruler to measure the length of each cold bending core, and take the average value of three measurements as the calibration result. 7.2 Calibration of the diameter of cold bending cores: Use a digital caliper to measure the diameter of each cold bending core, and take the average value of three measurements as the calibration result. For cold bending cores whose diameter cannot be measured with a digital caliper, a digital radius gauge with a resolution of 0.01mm can be used for calibration, and the average value of three measurements shall be taken as the calibration result. 8. Processing of calibration results: A calibration certificate shall be issued for the calibrated cold bending cores, and the calibration certificate shall indicate the calibration results and the measurement uncertainty. 9. Recommendations for calibration intervals: The calibration interval shall not exceed one year. The user may determine the re-calibration interval based on the calibration results, frequency of use, and usage conditions. If the inspection tool has been repaired during this period, it is recommended to recalibrate it.
