Moisture Transmission Test Procedure--Hydraulic Brake Hose Assemblies
J1873
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: Standard is referenced by new (work in progress) J3090 underhood hose standard, and is under consideration for being referenced by J1401 which is under revision. Therefore, the standard will remain active and will be updated. Updates are expected to be limited scope only (limited to, perhaps, revising the duration of water exposure).
