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 liquids which are transported through walls and joints are collected by a controlled flow of nitrogen (dry) and adsorbed by activated charcoal.

Rationale:

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.
