Calibration is a series of operations carried out to ensure the accuracy and reliability of measuring instruments or systems. It is a process that establishes the relationship between the values indicated by a measuring device or system under specified conditions and those of a reference device with known values. Calibration is essential to ensure that measurement results are reliable and conform to national and international standards.

Calibration Process

The calibration process includes the following fundamental steps:

1. Determining the Reference Standard: Calibration is generally performed with a reference standard that is known to have higher accuracy.

2. Making Measurements: The device is compared to the established reference standard for measurements.

3. Correction: If the device’s measurement results deviate from the reference values, necessary corrections are made.

4. Documentation: After the calibration process, the obtained results and corrections are documented and recorded.

Why is Calibration Important?

Calibration holds significant importance for various reasons:

• Accuracy: It ensures the reliability of measurements and prevents erroneous results.

• Compliance: It guarantees compliance with national and international standards, thus providing reliable service to customers.

• Quality Control: It enhances product quality and ensures traceability of processes.

• Safety: It increases safety in critical areas such as healthcare, automotive, and others, thereby reducing risks.

Calibration According to ISO/IEC 17025 Standard

Calibration processes should be performed in accordance with the international standard ISO/IEC 17025, which outlines the general requirements for the competence of testing and calibration laboratories. This standard was created to ensure that laboratories maintain a specific quality level while providing measurement and calibration services. It provides a framework to identify and certify laboratories that offer reliable and accurate calibration services to customers and the industry.

Calibration Process According to ISO/IEC 17025

A calibration process that complies with ISO/IEC 17025 typically includes the following elements:

• Documented Procedures: The laboratory must have written procedures that document the calibration process.

• Personnel Competence: Qualified personnel must be employed to conduct calibration operations.

• Traceability: Calibration must be based on traceable reference standards.

• Measurement Uncertainty: The laboratory must evaluate and report measurement uncertainty.

• Equipment Maintenance: Regular maintenance of the equipment used must be conducted, and calibration should be ensured as necessary.

• Record Keeping: All information related to the calibration process should be systematically recorded and archived.

Conclusion

Today, due to the necessity of accurate measurement in national and international trade, scientific research, and technological advancements, calibration of devices used in many sectors has become legally mandatory. The reliability of your devices directly affects the quality of your production. By implementing calibration processes, you can enhance the performance of your devices and increase your competitive edge in the industry.
