Pressure testing is a very small part of each of these standards. Nitrogen is used for its preservation properties. Pressure tests must always be performed under controlled conditions, following an approved test plan, and documented in a test record. Add to that the fact that our tools are more refined than old-school analog gauges and a leak of even 0.5 psi over a several hour period of time is easily something a technician can spot. Regardless of the method used, you will need access to a steady flow of nitrogen. A leak test procedure is usually a quality control step to assure device integrity, and should preferably be a one-time non-destructive test, without impact on the environment and operators. • Choose the most appropriate method, for example - a quick sweep with an electronic leak detector followed by a leak detection fluid (soapy water) to pinpoint the leaks. Standard Pneumatic Test - means a leak test of a pressure piping system using air or nitrogen, conducted by an organization that holds an Alberta certificate of authorization permit to construct pressure piping, using a procedure referenced in their QMS manual, and within the stored energy, temperature and material limitations established in this document.
