This SAE Recommended Practice is intended for all vehicle hydraulic brake hoses. It is an accelerated test which is intended to the user with a method of comparing the ability of hydraulic brake hose designs to retard the ingress of moisture into brake fluid.
This document specifies a laboratory performance requirement. ASTM D 1364 Interlaboratory reproducibility and correlation of data have not been defined, nor has correlation been established between field vehicle brake fluid moisture content and data obtained by this document.
The purpose of this recommended practice is to simulate in the laboratory the transmission of moisture into a brake hose.
