A New Fuel Permeation Test Set-up for SAE J1737 to Determine Hydrocarbon Liquid Losses Through Tubes, Hoses and Fittings 2001-01-1128

This ARDL proposed measurement practice is intended for the determination of the losses of hydrocarbon fluids, by permeation through component walls as well as through “micro leaks” at interfaces of assembled components while controlling temperature and pressure independently of each other. This is achieved by a new permeation test set-up using 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. This technique will be effective for measuring permeation of fuel components with permeation values above eight (8) grams per square meter per day. This experimental set-up is a low-cost fuel permeation measurement system compared to a measurement system with flame ionization detectors (FID).
