Published 1996-11-01 by SAE International in United States
This SAE Standard covers the minimum requirements for multilayer, nonmetallic tubing as manufactured as a liquid-carrying or vapor-carrying component for use in gasoline, alcohol blends with gasoline, or diesel fuel systems. Monowall tubing (one layer construction) is also covered by this document. The construction has one or more layers of polymer-based compounds in the wall, primarily for the purpose of improvement in permeation resistance to hydrocarbons found in various fuels. The construction can have a straight-wall configuration or can have a wall that is partially convoluted or corrugated. It may have an innermost layer with improved electrical conductivity for use where such a characteristic is desired; also, the improved electrical conductivity can apply to the entire wall construction, if the tubing is a monowall. This document is intended to cover tubing for any portion of a fuel system which operates above -40°C, and below 115°C, and up to a maximum working gage pressure of 690 kPa. The peak intermittent temperature is 115°C. For long-term continuous usage, the temperature shall not exceed 90°C. In some cases,…
