|Significance and Use|
4.1?Automobile and truck radiators and heater cores are now predominantly made with aluminum alloys using various manufacturing processes including brazing with a flux (See for additional information). The presence of residual internal brazing flux in heat exchangers along with the high ratio of internal aluminum surface area to coolant volume may affect certain physical and chemical properties and corrosion protection of the coolant. This test method provides a screening test to assess engine coolant physical and chemical properties and corrosion protection after aging it in a heat exchanger brazed with flux at elevated temperature under stagnant conditions. This method cannot stand alone as evidence of satisfactory coolant performance in flux-brazed aluminum heat exchangers. The actual service of an engine coolant formulation can be determined only by more comprehensive bench, dynamometer, and field tests.
1.1?This test method covers a laboratory screening procedure for evaluating engine coolant compatibility and corrosion protection after aging two weeks at 90 ?C in an aluminum heat exchanger brazed using flux.
1.2?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
