Product Code:SAE J1737
Title:Test Procedure to Determine the Hydrocarbon Losses From Fuel Tubes, Hoses, Fittings, and Fuel Line Assemblies By Recirculation
Issuing Committee:Fuel Systems Standards Committee
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.【英文标准名称】:RecommendedPracticeforTransportStreamVerificationinanIPTransportNetwork
