Test Method for Evaluating the Electrochemical Resistance of Coolant System Hoses and Materials

2018-11-21
CURRENT
J1684_201811
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.

CURRENT
J20/2_201803
This SAE Standard provides ordering information for any SAE 20R5 hose type (such as “EC, HT, LT” or combination thereof.) This is a wire-reinforced hose for coolant circulating systems of automotive type engines. This hose consists of a convoluted section with plain ends. The hose shall contain a wire helix or helices in the convoluted section. It is a supplement for Government use but may be used by others.

SAE Hose Measurement Study

CURRENT
J1759_201504
The Measurement of Coolant Hose task group conducted a round-robin study to determine the measuring capability of automotive suppliers and users to measure Inside Diameter (ID), Outside Diameter (OD), Wall Thickness (Wall) and wall thickness variation of hose using traditional measuring devices and techniques. Seven companies (five suppliers and two end users) participated in this testing. Based upon the round-robin study this information report will detail procedures, test measuring devices, results and recommendations.

Test Method for Evaluating the Electrical Resistance of Coolant System Hose Covers

2007-06-15
HISTORICAL
J2790_200706
This test method provides a standardized procedure for evaluating the electrical resistance of automotive coolant hose covers. It is know that an electrical potential exists between the engine and the radiator. Coolant hose cover conductivity has been determined to be a factor in reduced hose clamp life when vehicle build variations allow possible contact of the hose or the clamp to contact 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 conductivity of the tube portion of the coolant hose.
