What is traceability in calibration?
Traceability in calibration refers to the process of establishing a clear and unbroken chain of comparisons between a measurement result and a known reference point. This chain of comparisons ensures that the measurement result is accurate and reliable, and that it can be traced back to a recognized national or international standard. In other words, traceability is about being able to verify the accuracy of a measurement by linking it to a trusted reference point.
In the context of calibration, traceability is critical because it allows laboratories and testing facilities to ensure that their measurements are accurate and consistent. It also provides a level of confidence that the results are reliable and can be trusted. By establishing a clear chain of traceability, calibration laboratories can demonstrate that their measurements meet international standards, which is essential for industries that rely on precise measurements, such as aerospace, pharmaceuticals, and automotive.
