5.1 In the test method, coolants generally will be distinguished that have a tendency to foam excessively from those that are suitable for further evaluation to determine performance in actual service. 1.1 This test method covers a simple
glassware test for evaluating the tendency of non-aqueous engine
coolants to foam under laboratory controlled conditions of aeration
and temperature.
