Technidyne Sets the Standard for Calibration Standards

There is a high bar set for organizations seeking to provide ISO Level III Calibration Standards. It takes a serious investment in both equipment and the capabilities of technicians to qualify.

There are only four Authorized Laboratories around the globe. Technidyne Laboratory Services is the leading provider of ISO Level III optical property calibration standards in the world. In addition to being the only ISO Level III optical laboratory in the USA, our calibration laboratory is also the sole provider of calibration standards for many TAPPI methods, including TAPPI Brightness/Fluorescence, TAPPI Opacity and TAPPI Color.

As one of just a hand-full of Authorized Laboratories in the world, it is imperative that our facility is maintained with the best equipment and technical capabilities possible. Our lab follows ISO 17025 guidelines on documentation, training and competence. Likewise, our calibration laboratory is equipped with Master instruments for:

Technidyne became an ISO Level III Authorized Laboratory for optical calibration in 1997. In recent years, this process is described in ISO 4094 (General requirements for the competence of laboratories authorized for the issue of optical reference transfer standards of level 3). This ensures that Technidyne is maintaining the calibration scale in accordance with these guidelines. This includes monthly comparisons with the other Authorized Laboratories and regular comparisons with a Standardizing Laboratory. In addition, frequent communication and meetings among these labs help resolve any technical issues and challenges in maintaining the calibration scale for optical measurements. This ensures that paper, board, pulp and tissue producers as well as other users of these calibration standards around the world are receiving accurate and precise calibration.

Calibration is important, and it directly affects your bottom line. Your testing instruments are doing thousands and thousands of measurements each month, and testing inaccuracies can result in thousands and thousands of dollars in waste. Frequent preventative maintenance and instrument calibration can help you avoid a disaster in your mill. Think of it as an insurance policy. It’s a small investment that insures against expensive problems down the road. It only takes one quality claim or customer return to pay for years worth of routine maintenance on your laboratory or on-line instrumentation.

Calibration and preventative maintenance also directly affect the life span of instruments in your lab. With proper care and calibration, we often see Technidyne instruments working hard every day for 30 years and beyond.
