Significance and Use
4.1 The test method will generally identify coolants that have a tendency to foam excessively at room temperature.
Note 1—
In use, the foaming tendency of a coolant solution may be increased by service aging or contamination.
1. Scope
1.1 This test method applies to a simple shake test for evaluating the tendency of an aqueous solution of engine coolant to foam at room temperature.
1.2 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.
