Standard Test Method for Simulated Service Corrosion Testing of Non-Aqueous Engine Coolants

Importancia y uso:

5.1 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 D7935/D7935M). 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.

5.2 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 and from field testing in actual service.

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

5.4 The substitution of components in the apparatus of Section 6 is permissible if agreed upon by the contracting parties.
