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.
