Abstract: What does witness testing consist of? It is normally two or more persons meeting at a designated location on time to verify the calibration of the measurement equipment on a specific location where gas is purchased or bought. This consists of a procedure which everyone approaches in their own way, where all steps are covered and documented on a report. The testor and witness should be knowledgeable of what to check for, and see that all steps check out and are corrected if needed.
