This is NOT my personal interpretation of this ASME B31.3 “leak testing” requirement(s), but it is the official position of the Alberta Canada pressure equipment safety authority. I share this as another “official” explanation of what ASME B31.3 requires in terms of pressure/leak testing and this regulatory agency’s interpretation of how they read this critical RAGAGEP. Pressure testing and leak testing still cause quite a heated debate with far too many businesses that are storing, processing, and handling hazardous materials via piping circuits and in the Year 2021, we should be well beyond these debates!
