Standard Test Method for Foaming Tendencies of Non-Aqueous Engine Coolants in Glassware
N ASTM D7840
Annotation
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.
Units-The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
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. For specific warning statements, see 7.2 and 7.3.
