This test method covers the determination of foaming properties of surface-active agents. Glass tubing apparatus for this test method shall include pipet and a receiver. Apparatus requirements like dimensions, shape, calibration marks, rubber stoppers, etc., shall conform to the specifications as indicated in this standard method. Test solution preparation shall include water preheating, adding the surface-active agent while stirring, and solution aging. Test procedure for foaming properties determination shall be done while surface-active solution is aging as indicated in this standard test method. Report shall include test solution concentration, temperature, water hardness, and foam height.


1.1 This test method covers the determination of the foaming properties of surface-active agents as defined in Terminology D459. This test method is applicable under limited and controlled conditions, but does not necessarily yield information correlating with specific end uses. This method is subjected to the operator of the method as the foam heights are not always level and an average height is determined by the user so it is more of a qualitative measurement in these instances. However, for foam measurements results taken on more flat uniform samples this method has more of a quantitative quality.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
