Scope
Content
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.
Rationale
Content
The Fuel Systems Technical Standard committee which created this document has not further developed this method since the last publication. The technology of this document is stable. Aggressive evaporative emissions regulations in the US limit the application of high permeation lines which can be qualified using this method. The method may have application to other markets or industries.
