SAE J1737

Description / Abstract: 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 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.
