Significance and Use

This test method, by a closer approach to engine cooling system conditions, provides better evaluation and selective screening of engine coolants than is possible from glassware testing (Test Method D 1384). The improvement is achieved by controlled circulation of the coolant, by the use of automotive cooling system components, and by a greater ratio of metal surface area to coolant volume.

Although this test method provides improved discrimination, it cannot conclusively predict satisfactory corrosion inhibition and service life. If greater assurance of satisfactory performance is desired, it should be obtained from full-scale engine tests (Test Method D 2758) and from field testing in actual service (Practice D 2847).

Significance and interpretation of the test and its limitations are discussed further in Appendix X1.

If this test method is used as a qualification test for Specification D 3306 and Specification D 4985, the recommended components listed in Section 5 shall be used. If it is not being used for such qualification purposes, then suitable substitution components may be used, if agreed upon between the contracting parties.


1.1 This test method evaluates the effect of a circulating engine coolant on metal test specimens and automotive cooling system components under controlled, essentially isothermal laboratory conditions.

1.2 This test method specifies test material, cooling system components, type of coolant, and coolant flow conditions that are considered typical of current automotive use.

1.3 The values stated in foot-pound-second units are to be regarded as the standard. The values given in parentheses (SI units) are approximate equivalents for information only.

1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 6.
