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.

This SAE Recommended Practice covers the application of hydraulic brake hose (as defined by current issue of SAE J1401) as used to provide a flexible hydraulic connection between wheel end or axle brake system components on motor vehicles. The purpose of this document is to outline design, operating, and service factors in routing a hydraulic brake hose assembly to a vehicle. It is intended to serve as a recommended practice for original equipment manufacturers. Vehicle design circumstances may exist that prevent strict adherence to this document. Any deviations should have the concurrence of all engineering functions involved.

This SAE Standard specifies the performance tests and requirements for hydraulic brake hose assemblies used in the hydraulic braking system of a road vehicle. It also specifies the methods used for identification of the hose manufacturer.

This document applies to brake hose assemblies made of a hose fabricated from yarn and natural or synthetic elastomers and assembled with metal end fittings for use with nonpetroleum-base brake fluids as specified in SAE J1703, SAE J1704 and SAE J1705.

The nominal internal diameter of the brake hose shall fall within one of the following values:

a. less than 4 mm (1/8 in or less)
b. 4 to 5 mm (3/16 in)

This recommended practice describes the equipment, test procedure, and performance requirements for high temperature impulsing of automotive brake hose assemblies with hydraulic brake fluid.

This SAE Information Report is the listing of recommendations for the proper packaging, storage, and shelf life limitations of new and unused hydraulic brake hose assemblies. The document embodies the testing, analysis, and experience of many users and manufacturers. Where specific manufacturer's recommendations are made, those recommendations shall supersede the recommendations of this document. This document describes the successful procedures and practices associated with brake hose assemblies usage by a wide cross section of manufacturers and users over several years. The practices are expected to be applicable to all brake hose assemblies which qualify under SAE J1401.

The purpose of this recommended practice is to evaluate in the laboratory the effect of flexing on a brake hose when exposed to a high ozone concentration environment. This recommended practice is intended for all vehicle hydraulic brake hoses. It is an accelerated test which subjects the hose to dynamic ozone exposure.

The specification covers hose fabricated from fabric braid and synthetic rubber, assembled with end fittings for use in automotive power steering applications at pressures as indicated in Table 1, as flexible connections within the temperature range of –40 C (–40 F) to 121 C (250 F) average, 149 C (300 F) maximum peaks. These hoses are intended for use in applications where reduction in amplitude of pump pressure pulsations is not required.

This specification covers hose fabricated from wire braid and synthetic rubber, assembled with end fittings for use in automotive applications up to 1500 psi maximum pressure, as flexible connections Within the temperature range of –40 to +121 C (–40 to +250 F) average, 149C (300 F) maximum peaks.

This specification covers two types of hose fabricated from fabric braid and synthetic rubber, assembled with end fittings for use in automotive power steering applications as flexible connections within the temperature range of –40 to +121 C (–40 to +250 F) average, + 149 C (+ 300 F) maximum peaks. These hoses are intended for use in applications where reduction in amplitude of pump pressure pulsations is required. Type 1 hose shall be suitable for 1500 psi maximum working pressure. Type 2 hose shall be suitable for 1300 psi maximum working pressure.

This specification covers hose fabricated from fabric braid and synthetic rubber, assembled with end fittings or user applied clamps for use in automotive power steering applications as flexible connections within the temperature range of –40 C ( – 40 F) to +121 C ( + 250 F) average, 149 C (300 F) maximum peaks. Hose assemblies shall be suitable for 250 psi maximum working pressure with end fittings and 100 psi maximum working pressure with user applied clamps.
