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 number 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 to foam under low shear conditions.NOTE1Foam under high shear is covered by Test Method D3519which uses a commercial blender.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are provided forinformation only.1.3This standard does not purport to address 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 Documents2.1 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 1.8F).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 liquid 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 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 necessarily predict the foaming tendencyof the liquid(that is,metalworking coolant)at some other usetemperature.5.Apparatus5.1 Water Bath,constant-temperature,suitable to hold sev-eral bottled emulsions at 25 6 1C(77 6 1.8F)for 1 to 2 h.NOTE3A common household dishpan is satisfactory when the testtemperature is close to room temperature.5.2 Stop Watch or Timer,capable of measuring 5 min 6 0.2s.5.3 Bottles,clean or new,clear glass,16-oz(narrow mouth),with screw neck.3The 16-oz bottle is 64164in.(169 mm)tall1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products and Lubricants and is the direct responsibility of SubcommitteeD02.L0.01 Metal Removal Fluids and Lubricants.Current edition approved May 1,2007.Published June 2007.Originallyapproved in 1988.Last previous edition approved in 2002 as D3601 88(2002)1.DOI:10.1520/D3601-88R07.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.316-oz Round Packer,Brockway Glass Co.,Mold No.1094 or 16-oz BostonRound,as shown in Fig.1 is suitable for this purpose.Bottle takes Cap No.28.Standard Glass Container Series No.80 specifies approximate weight of glass,etc.,on drawing No.C-8010 obtainable from Glass Container Manufacturers InstituteInc.,330 Madison Ave.,New York,NY 10017.FIG.1 Boston Round Bottle.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.and has a maximum diameter of 23132in.(75 mm).The outsideneck is932in.(7.1 mm)and the shoulder radius is 1 in.(25.4mm).5.4 Syringe or Transfer Pipet.45.5 Rule,millimetre,at least 150 mm in length.6.Materials6.1 Distilled Water.6.2 Hard Water,20 000 ppm prepared by dissolving 29.4 gof reagent grade(ACS standard)CaCl2 2H2O in 1 litre offreshly boiled distilled water(used only where distilled wateris used as in Note 5).7.Procedure7.1 Fix a label or other means of marking total heights to theoutside of the bottle.NOTE4Waterproof medical adhesive tape makes satisfactory water-proof labels,which readily take pencil marks.57.2 Using the manufacturers recommended procedure,pre-pare 200 ml of emulsion at the recommended concentrationand pour the emulsion into the 16-oz round bottle(or equiva-lent 500-cm3bottle).7.3 When natural water is used,record water hardness(using Test Method D1126),source,and date obtained.NOTE5In the absence of manufacturers recommendations,place 1904Disposable pipets,Thomas Scientific Co.Sa
