Calibration is vitally important wherever measurements are important, it enables
users and businesses to have confidence in the results that they monitor, record
and subsequently control.
Calibration is the process of comparing a reading on one piece of equipment or
system, with another piece of equipment that has been calibrated and referenced
to a known set of parameters. The equipment used as a reference should itself
be directly traceable to equipment that is calibrated according to ISO/IEC 17025.
ISO/IEC 17025 is the International Standard for the accreditation of Testing and
Calibration Laboratories. It includes quality management system requirements
along with technical requirements.
Calibration defines the accuracy and quality of measurements recorded using a piece of equipment. Over time there is a tendency for results and accuracy to ‘drift’ when using particular technologies or measuring particular parameters such as temperature and humidity. To be confident in the results being measured, there is an ongoing need to maintain the calibration of equipment throughout its lifetime for reliable, accurate and repeatable measurements.
The goal of calibration is to minimize any measurement uncertainty by ensuring the accuracy of test equipment. Calibration quantifies and controls errors or uncertainties within measurement processes to an acceptable level. In manufacturing process applications, any equipment used should be calibrated at multiple points across its working range to ensure reliable information to critical alarms and systems. Failure to calibrate or improper calibration has been the cause of injury, death and even major environmental disasters. Over time, any measuring device’s accuracy will begin to decline. Usually, this decreased accuracy is due to standard wear on various components, but it can also occur due to a harmful environment or mechanical or electric shocks. The rate at which measuring equipment ill lessen can vary based on its surroundings and type. Due to this reduction in measuring accuracy, organizations with measuring equipment prioritize regular calibration. Calibrating equipment, ensure it has the precision required to complete tasks correctly. Calibrating measuring devices also ensures to maintain a high level of product quality.
When a company calibrates its equipment, it can receive several benefits. Some
of these advantages include
