Standard Test Method for Foam in Aqueous Media (Blender Test) (Withdrawn 2013)
SIGNIFICANCE AND USE
The results obtained by the test method described are useful as guides in determining the tendency of a water-based metalworking coolant to produce foam under high shear conditions. No correlation with changes in heat transfer, pumpability, or other factors affected by foam is intended. The foam produced by any given industrial process depends on the method by which the foam is generated and may not be directly proportional to that produced by this carefully controlled laboratory test method. Further, the foam generated at the specified test temperature will not necessarily predict the foaming tendency of the liquid (that is, metalworking coolant) at some other use temperature.
SCOPE
1.1 This test method covers the measurement of the increase in volume of a low-viscosity aqueous liquid (less than 3 cSt at 40°C) due to its tendency to foam under high shear conditions. Note 1 - Foam under low shear is covered by Test Method D 3601.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
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 safety information, see 7.16.
WITHDRAWN RATIONALE
This test method covers the measurement of the increase in volume of a low-viscosity aqueous liquid (less than 3 cSt at 40°C) due to its tendency to foam under high shear conditions.
Formerly under the jurisdiction of Committee D02 on Petroleum Products and Lubricants, this test method was withdrawn in May 2013 due to lack of interest in its continued use.

Caution—The round robin on this test used distilled water and a controlled synthetic hard water to make data comparative to the products under test at different
places and at different times. Care must be exercised when natural waters are used that comparative samples are used in exactly the same water, taken at the same
time from the same source. (For instance, well waters can change in hardness rapidly depending on the change in demand within the hour.)
