Standard Test Method for Simulated Service Corrosion Testing of Engine Coolants
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
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 either SI or inch-pound units are to be regarded as the standard. The values given in parentheses 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.
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
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
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
