What is Traceability?

Traceability can be defined as an unbroken record of documentation (e.g., “documentation traceability”) or an unbroken chain of measurements and associated uncertainties (e.g., “metrological traceability”). When we use the word “traceability” in this paper, we will always mean “metrological traceability.” The National Institute of Standards and Technology maintains the U.S. national standards for temperature. In other countries, similar national standards laboratories perform the same function. The readings of a thermometer  like a

How To Prevent Electrical Shocks Through Insulation Resistance Testing

Why Have an Insulation Resistance Testing Program? A regular program of insulation resistance testing is strongly recommended to: Prevent electrical shocks Assure safety of personnel Reduce or eliminate down time Detect deterioration of insulation Evaluate the quality of repairs This type of program is helpful in identifying when to schedule repair work such as: vacuum cleaning, steam cleaning, drying and rewinding. Quality…
