SAE J1737-2019 PDF

Scope: "This SAE Recommended Practice is intended for the determination of the losses of hydrocarbon fluids@ by permeation through component walls as well as through ""microleaks"" at interfaces of assembled components while controlling temperature and pressure independently of each other. This is achieved in a recirculating system in which elements of a test fuel that permeate through the walls of a test specimen and migrate through the interfaces are transported by a controlled flow of dry nitrogen to a point where they are measured. That measurement point is a device@ such as a canister containing activated charcoal or other means of collection or accumulation where the hydrocarbon losses are then measured by weight change or analyzed by some other suitable means."
