Primaarikalibrointi, also known as primary calibration, is a fundamental process in the field of metrology, which is the science of measurement. It involves the establishment of a measurement standard or reference that is traceable to an international standard. This process is crucial for ensuring the accuracy and reliability of measurements across various scientific and industrial applications.

Primary calibration typically occurs at the highest level of the calibration hierarchy. It is performed by national metrology institutes or designated calibration laboratories that maintain the national standards for specific measurement quantities. These institutes use advanced techniques and equipment to compare the measurement standard under calibration with a primary standard, which is a reference standard that is assumed to be accurate and traceable to an international standard.

The primary standard serves as the foundation for all subsequent calibrations. It is used to calibrate secondary standards, which in turn are used to calibrate working standards. This hierarchical structure ensures that measurements are consistent and comparable across different laboratories and organizations.

Primary calibration is essential for maintaining the integrity of measurement systems and for ensuring compliance with regulatory requirements. It helps to identify and correct any systematic errors or biases in measurement instruments, thereby improving the overall accuracy and precision of measurements. Additionally, primary calibration plays a vital role in scientific research, quality control, and industrial processes where precise measurements are critical.

In summary, primaarikalibrointi is a critical process in metrology that involves the establishment of a measurement standard traceable to an international standard. It is performed at the highest level of the calibration hierarchy by national metrology institutes and is essential for ensuring the accuracy and reliability of measurements across various applications.
