This SAE Standard presents the minimum requirements for nonmetallic tubing with one or more layers manufactured for use as liquid carrying DEF lines for diesel engine selective catalyst reduction (SCR) after-treatment systems. Requirements in this document also apply to monowall tubing (one layer construction) and multi-layer constructions. Unless otherwise agreed to by suppliers and users this document applies to tubing for any portion of the DEF system that might operate continuously at temperatures above –40 °C and below 120 °C or for high temperature systems up to 160 °C. Maximum working pressure of 1140 kPa absolute. The tubing can be used at the peak intermittent exterior temperature up to 140 °C or 180 °C. Tubing systems supplied to this application are usually required to thaw from the frozen condition using various heating methods in operation complying with EPA requirements.
