By Richard Fertell, Hamed Ershad, York Xu, Osborne Gumbs, Tammy Tran This article is the first of a series describing how to perform liquid flow rate calibrations at fluid temperatures below +5 °C and above […]
by Christopher L. Grachanen On July 22, 2016, the US Bureau of Labor Statistics (BLS) published their second federal register denoting proposed changes and additions for the upcoming 2018 Standard Occupational Classification (SOC) system. The […]
by Dr. George Anastasopoulos As we discussed in my previous relative article “The new ISO/IEC 17025 – What to expect”, ISO/IEC 17025 was first issued in 1999 by the International Organization for Standardization (ISO) and […]
by Ted Doiron While check standards will eventually give the most accurate uncertainty for a calibration procedure, the time and expense can be discouraging. Another common method, standard Gage Repeatability and Reproducibility study does not […]
by Michael Boetzkes Not too long ago, the RH calibration chambers which were appropriate for calibrating the high accuracy RH transmitters were limited to custom build chambers at the sensor manufacturer and a very small […]
by Dr. George Anastasopoulos ISO/IEC 17025 was first issued in 1999 by the International Organization for Standardization (ISO) and the International Electro-technical Commission (IEC). It is the single most important standard for calibration and testing […]
by Mettler Toledo Calibrating a weight of unknown mass requires comparison to a known reference. It’s not as simple as it sounds, however, particularly when manufacturing weights or establishing metrology standards. During manual calibration, everything […]
by Henry Zumbrun There has been ongoing debate as to whether or not a hydraulic force machine that applies the force simultaneously to both the reference standard and the unit under test is more repeatable […]
