Designation:D1370/D1370M12Standard Test Method forContact Compatibility Between Asphaltic Materials(OliensisTest)1This standard is issued under the fixed designation D1370/D1370M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method provides a means for evaluatingcontact compatibility between asphaltic materials.It is gener-ally used to determine compatibility between the saturant andcoating used in the manufacture of prepared roofings.2Coatingand saturant will be referred to,but comparable asphalticmaterials may be tested where this test procedure seemsapplicable.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This 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.2.Referenced Documents2.1 ASTM Standards:3E11 Specification for Woven Wire Test Sieve Cloth and TestSieves3.Summary of Test Method3.1 A small drop of molten saturant is placed on the freshlytalced surface of the coating,and compatibility is judged by thedegree to which an oily ring develops in the talc surroundingthe drop.24.Significance and Use4.1 This test method assesses the degree to which asphaltsinteract with one another.It can indicate possible futureproblems,especially blistering,in a roofing product if incom-patible asphalts are in contact in the product.5.Apparatus5.1 Container,lid of 85-g 3-oz ointment box,or equivalentcontainer.5.2 Analytical Balance,having an accuracy of 61.0 mg.5.3 Sieve 45-m(No.325).Detailed requirements for thesesieves are given in Specification E11.5.4 Dropping Device,a fine wire 1.0 mm 0.04 in.indiameter.5.5 Oven,constant-temperature,capable of maintaining thetest temperature within 61.0C 61.8F.5.6 Small Scale,graduated in 0.1 mm divisions.5.7 Magnifying Glass or Stereo Microscope,approximateminimum of 4.5.8 Talc,pure,of the soapstone variety,ground so that atleast 70%passes the 45-m(No.325)sieve,and oven-dried at110C 230F.NOTE1When this test method is being used in purchase specifica-tions,both the purchaser and the seller shall use the same talc.Talc fromLuzenac America,Inc.4has been found to be suitable for this test.6.Procedure6.1 Melt a portion of the coating at the minimum tempera-ture required to render it fluid,stirring with the fine wire toeliminate bubbles,and pour it into the clean 85-g 3 oz tin lidto a thickness of 3.0 to 6.0 mm18to14in.Pour carefully,soas to provide a substantially smooth surface free of bubbles andother surface blemishes.After the coating material has cooled,determine the weight and surface area of the filled container.1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of Subcommittee D08.02 on SteepRoofing Products and Assemblies.Current edition approved July 15,2012.Published August 2012.Originallyapproved in 1984.Last previous edition approved in 2007 as D1370 00(2007).DOI:10.1520/D1370_D1370M-12.2This test determines only exudative incompatibility.For application of thisprocedure to determination of insudative incompatibility,see“Compatibility Be-tween BitumensExudation versus Insudation,”by Oliensis,G.L.,MaterialsResearch and Standards,Vol 1,No.9,September 1961,p.723.3For 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.4The sole source of supply known to the committee at this time is the LuzenacAmerica,Inc.,9000 East Nichols Avenue,Englewood,CO,80112.If you are awareof alternative suppliers,please provide this information to ASTM Headquarters.Your comments will receive careful consideration at a meeting of the responsibletechnical committee,1which you may attend.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.2 Make a preliminary dusting of talc by covering thecoating surface with talc and removing the excess,nonadherentdust by inverting the container and dropping it approximately25 mm 1 in.onto the table top.6.3 Make a final application of talc through the 45-m(No.325)sieve,held 20 to 25 mm 34to 1 in.above the surface ofthe coating,by gently shaking or tapping the sieve until asmooth,uniform film of talc,weighing 0.004 g
