1、Designation:D3601 88(Reapproved 2007)Standard Test Method forFoam In Aqueous Media(Bottle Test)1This standard is issued under the fixed designation D3601;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A num
2、ber in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the measurement of the increasein volume of a low-viscosity aqueous liquid(less than 3 cSt at40C)due to its tendency t

4、s all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specific safetyinformation,see 7.13.2.Referenced Documents
5、2.1 ASTM Standards:2D1126 Test Method for Hardness in WaterD3519 Test Method for Foam in Aqueous Media(BlenderTest)3.Summary of Test Method3.1 The increase in volume is determined by the increase intotal height of the test fluid,including foam,after vigorousshaking of the emulsion at 25 6 1C(77 6 1.
6、8F).NOTE2Water that is normally used to reduce the concentrate to aworking consistency can be used.However,if this type of water is notdesirable or available,two other types of water may be used to prepare thetest liquid:(1)distilled water or(2)distilled water with a subsequentseeding of the test li
7、quid with synthetic hard water.4.Significance and Use4.1 The results obtained by this test method are useful asguides in determining the tendency of a water-based metal-working coolant to produce foam under low shear conditions.No correlation with changes in heat transfer,pumpability,orother factors
8、 affected by foam is intended.The foam generatedby any given industrial process depends on the method bywhich the foam is generated and may not be directly propor-tional to that produced by this controlled laboratory testmethod.Further,the foam generated at the specified testtemperature will not nec
