Nonmetallic EGR Tubing with One or More Layers
This SAE Standard presents the minimum requirements for nonmetallic tubing with one or more layers manufactured for use in exhaust gas recirculation systems Requirements in this document apply to monowall tubing (one layer construction) and multilayer tubing. The tube construction can have a straight wall configuration, a wall that is convoluted or corrugated, or a combination of each.
Rationale: An industry standard for exhaust gas recirculation (EGR) tubings do not exist. This standard was developed to screen appropriate tubing materials and standardize test procedures for assemblies in the automotive industry.
