Calibrations should be performed by people who have been appropriately trained and qualified for the job. Depending on the complexity of the calibration process and the type of equipment being calibrated, the specific qualifications and experience necessary may vary. Following are some general guidelines:
Technicians with particular knowledge in calibration processes are frequently sufficient for routine calibrations of devices such as pressure transmitters, temperature sensors, or flow meters. They should be able to follow established protocols and understand the principles of the calibration process.
Calibration Technicians are in charge of calibrating, inspecting, testing, maintaining, and repairing instruments, meters, gauges, and other testing and measuring equipment. A Calibration Technician’s job is to ensure the accuracy and precision of measurements performed with this equipment.
Calibration technicians can obtain accreditation in specific industries. These certifications verify that technicians achieved a specified level of calibration knowledge and skills.
Calibrations are usually carried out by engineers specialized in instrumentation and control systems, particularly in complicated industrial environments. They may be more knowledgeable about the instruments and the overall control system.
It is best to employ an ISO 17025-accredited calibration laboratory for calibrations that require a high level of precision or for instruments used in critical applications. These labs have proved expertise and fulfill international calibration requirements.
Representatives from the equipment manufacturer may be involved in the calibration process in some situations, particularly with specialized or complex instruments. They are quite knowledgeable about their stuff.
ISO 17025 is the primary internationally standard for testing and calibration laboratories’ competence. It is used by laboratories of all sizes to ensure their customers that they are operating competently and generating valid results, enhancing confidence in their work.
ISO/IEC/EN 17025 (accredited): the most strictest worldwide recognized standard. Issues “General Requirements for the Competence of Calibration and Testing Laboratories” .
It is critical to note that whoever performs the calibration must follow specified standards and procedures. Proper calibration documentation, including before-and-after readings, should be kept. Calibration intervals should be chosen based on the instrument’s unique requirements and industry regulations.
The ultimate goal is to ensure that calibrations are performed precisely and consistently in order to maintain the accuracy and performance of measurement instruments…
