Impartiality in ISO 17025 ensures that laboratory results are objective, unbiased, and free from conflict of interest. To implement impartiality effectively: Since the transition from the 2005 version to the 2017 version has started, I have received several comments regarding … Read More

Have you ever wondered why we need to use a calibrated thermometer to monitor food temperatures regularly or at a set time? During my shift in one of the restaurants I worked at, we monitored the temperature of the chilled … Read More

As a Calibration technician, or quality personnel, have you felt confused about whether to perform calibration or verification on a specific instrument? How can you tell if you only need verification? Or Just calibration? What needs to be performed first, … Read More

Have you encountered the following scenario? You are interpreting a calibration certificate but you noticed that the correction factor you need is not exactly displayed or provided in the report, what can you do? The measurement data of your instrument … Read More

Weighing scales are the need of almost every business. Some people also use weighing scales at home to monitor their body weight. A scale is a measuring device that allows you to determine the mass and weight of an object. … Read More

You may have a properly maintained calibration lab, well-trained personnel, high-end measuring equipment but the traceability of the reference standard you use is in question, then the calibration performed could be rejected. As a beginner once in calibration, my only … Read More

Before considering using a balance or performing a weighing scale verification, one primary requirement is to know the tolerance limit. The user should determine the tolerance limit in consideration of their process, but this is not always the case. As … Read More

Are you qualified to perform the calibration? This is the question I sometimes encounter during assessment or audits related to the competency of personnel. Personnel competency is one of the main requirements in a calibration process where auditors are so … Read More

Let me ask you a question, have you ever used the Measurement Uncertainty (MU) reported in your calibration certificate? Most users of certificates that I meet who are In-charge in calibration do not use the measurement uncertainty results in their … Read More

You received a pressure gauge calibration certificate with the following results: You are asked to interpret these results to determine if the results of the calibration have passed or failed by accounting the measurement uncertainty in the measurement results before … Read More
