Quality Starts with Annual Measuring Instrument Calibrations

Quality Starts with Annual Measuring Instrument Calibrations

To understand the importance of calibrating your measuring instruments you must first understand the definition of calibration.

In accordance to the International Vocabulary of Basic and General Terms in Metrology (VIM), Calibration is the comparison of a measurement instrument to a standard of a higher level.  This process is done under controlled and specified conditions in order to document the accuracy of the instrument under test.

Eliminating factors that may provide inaccurate data plays a very important role in any quality control department. Let’s take that process a step further. While we stress the importance of instrument calibrations, we also stress the crucial step of continuing those calibration techniques on an annual or semi-annual basis, depending on the use and application of the instrument. Calibrating your measuring instrument on a set schedule will minimize the chance for inaccurate measurements and remains a fundamental aspect of the instrumentation design.

Choosing an ISO/IEC 17025 Accredited Lab

Originally issued back in 1999 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), the 17025 Accreditation is the single most important standard for calibration and testing laboratories worldwide. Any laboratory accredited to this international standard has demonstrated that they are technically competent and able to produce precise and accurate calibration data. You may be thinking, “What’s the big deal?” The difference between a company stating they perform instrument calibrations and a company that is actually accredited to do so is simple, QUALITY. You are absolutely right in thinking that you can get your instruments calibrated anywhere, “If they say they calibrate, they must know what they are doing right?” WRONG! Companies that are accredited to the 17025 standard are not only regularly evaluated to the most rigorous of technical evaluations, but they have to maintain the highest of quality standards within their quality management system to comply with the ISO/IEC 17025 accreditation.
