ASTM D2570-96(2002)

Standard Test Method for Simulated Service Corrosion Testing of Engine Coolants

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.
