This test method provides a standardized procedure for evaluating the electrochemical resistance of automotive coolant hose and materials. Electrochemical degradation has been determined to be a major cause of EPDM coolant system hose failures. The test method consists of a procedure which induces voltage to a test specimen while it is exposed to a water/coolant solution. Method #1, referred to as a “Brabolyzer” test, is a whole hose test. Method #2, referred to as a “U” tube test, uses cured plate samples or plates prepared from tube material removed from hose (Method No. 2 is intended as a screening test only). Any test parameters other than those specified in this SAE Recommended Practice, are to be agreed to by the tester and the requester.
This SAE Standard covers nonreinforced, extruded, flexible tubing intended primarily for use as fluid lines for automotive windshield washer systems which conform to the requirements of SAE J942.

This SAE Standard covers the minimum requirements for a low-permeation tubing (100 g/m2/day or less) for use as a low pressure (14.5 kPa) liquid- or vapor-carrying component for use in gasoline or diesel fuel filler, vent, and vapor systems. The construction shall be designed to be functional over a temperature range of -40 to 100 °C for the T1 designation, or -40 to 125 °C for the T2 designation.
This SAE Recommended Practice covers recommended practices for design and evaluation of hose clamped joints primarily in automotive applications. It is intended to: (a) evaluate current joint designs, (b) compare existing designs, (c) aid in the development of new designs, (d) give objective results once weights are set, (e) rate the overall design and individual sections of design, and (f) encourage future research by industry and the OEM's.
This test method provides a standardized procedure for evaluating the electrical resistance of automotive coolant hose covers. It is known that an electrical potential exists between the engine and the radiator. Coolant hose cover conductivity has been determined to be a factor to reduce hose clamp life when vehicle build variations allow possible contact of the hose or the clamp to metal components on the radiator and engine thus completing an electrical circuit. The ensuing electrical current can undercut the clamp protective coating, leaving it vulnerable to the corrosive effects of road salts, moisture, and other environmental contaminants. SAE Recommended Practice J1684 addresses the electrochemical resistance of the tube portion of the coolant hose.
This SAE Standard covers hose intended for use with automatic transmission cooling system applications. Type A hoses are intended for original equipment or replacement applications while Type B hoses are intended for aftermarket auxiliary cooler applications only. The reference fluid for tests requiring the use of automatic transmission fluid (ATF) shall be Dexron III / Mercon 5 or equivalent ATF that is agreed to by hose manufacturer and customer.
This SAE Recommended Practice is used for establishing the compression set that could be expected to occur with a thermoset elastomeric hose under securing clamps. It seeks to reproduce the type of indentation caused by the clamps in the wall of a hose. An excessive compression set measured by this method may indicate a hose that could eventually allow leakage of fluid or gas past the clamps in service.

This SAE Recommended Practice is used for establishing the compression set that could be expected to occur with engine coolant hoses under securing clamps. It seeks to reproduce the type of indentation caused by the clamps in the wall of the hose. An excessive compression set measured by this method would indicate a hose that could eventually allow leakage of coolant past the clamps in service. This method has been found to give repeatable results in the range of 25% to 50% initial compression.
The purpose of this SAE Recommended Practice is to provide dimensions for both standard and thin-wall hoses and to provide commercial and precision tolerances for SAE 20R3 and SAE 20R4 coolant system hoses.
This SAE Standard outlines the requirements for a preformed thermosetting hose intended for use in heavy-duty vehicle engines, such as air cleaner to carburetor hose, where it is exposed to normal heat and splash of motor oil.
This specification covers hose which may be supplied either coupled or uncoupled for use with gasoline, diesel fuel, lubricating oil, or the vapor present in either the fuel system or in the crankcase of internal combustion engines in mobile, stationary, and marine applications. The hose may be furnished in long lengths, specific cut lengths, or as a part preformed to a specific configuration.
