In our daily measurement activities, calibration isn’t just a technical requirement—it’s a commitment to quality and reliability. Whether you’re in manufacturing, pharmaceuticals, food safety, or laboratory work, confidence in decision-making starts with reliable and accurate calibration results, which are the … Read More

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

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

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

I receive a question asking, “What is the difference between monitoring and calibration?” At first, I was skeptical to answer the question because I was thinking that it is a very simple question. But I realize that it is not … Read More

ISO/IEC 17025:2017 Requirements: List of Documents Outline and Summary One of the most challenging parts during establishing a calibration or testing lab is to start the documentation requirements, even if there is an established guide (ISO 17025) that we can … Read More

During my time as a calibration engineer managing an in-house calibration lab, I have collected different types of calibration certificates coming from different users inside the company. I observed that each certificate has different formats and contents. And one day, … Read More

Are you aware of the requirements to generate a calibration certificates? One of the very first things to have during the start of any calibration activity is to prepare the necessary documents like calibration methods, forms, and work instructions in … Read More

This is a guest post from Edward Simpson, calibration and technical engineer, RS Calibration. The economic success of most manufacturing industries critically depends on the quality of their products, and measurement plays an important role in this. Every measuring device … Read More

I have received the below comments in relation to the last post about the differences between calibration, verification, and validation. These are the comments: Can you give an example instrument with a specification that we can determine or differentiate calibration, … Read More

Calibration, verification, and validation are always used or read in every measurement related topic. When I was just starting out in this calibration environment, I was always confused on how or when to use each term. There were so many … Read More

One of the main goals in every industry whether in manufacturing or in service, is to have a smooth and reliable operation of every equipment or machine used. One way to achieve this goal is to implement a quality control … Read More

As a calibration tech or Engineer, our responsibility does not end after we performed instrument calibration. One of our responsibility is also to respond to or support an audit.  As per my experience, the most audited processes in the manufacturing … Read More

I was messaged by one of my reader about a question related to my previous post about “How to Interpret a Calibration Certificate”. See the post here.  It is a good question because I did not cover it on the … Read More

As a Calibration Technician, an Equipment Engineer, a QA, or just a user of a calibration certificate, let me ask you below questions: Q1: Do you know how to interpret a calibration certificate during measurements and/or preventive maintenance? Q2: If … Read More

Why is Calibration Not Required? During my career as a calibration engineer in an in-house calibration laboratory, one of our goals is to provide 100% calibration to all measuring instruments that are being used inside our facility that directly or … Read More

As a calibration technician, I am exposed to a vast number of measuring instruments like pressure instruments, transmitters, electrical equipment  and temperature measuring devices. Every industry that I encounter have all these monitoring and measuring instruments being used. And if … Read More
