Moisture Transmission Test Procedure - Hydraulic Brake Hose Assemblies
J1873_201202
This SAE Recommended Practice is intended for all vehicle hydraulic brake hoses. It is an accelerated test which is intended to provide 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.
Rationale:
Sections 2.1.1 and 4 of this specification have been updated to create a reference to SAE J1703 and J1704 where previous revisions listed the referee brake fluid formulation for DOT 3 fluid only. The industry is trending towards use of both DOT 3 and DOT 4 for global applications, and the formulation of the referee fluids is changing more rapidly. A direct reference to the brake fluid specifications will provide more accurate information as these referee brake fluid formulations change.
