Designation:D1370/D1370M12(Reapproved 2021)Standard 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 are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.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 61.0 C 61.8 F.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 at110 C 230 F.NOTE1When this test method is being used in purchasespecifications,both the purchaser and the seller shall use the same talc.Talc from Luzenac America,Inc.4has been found to be suitable for thistest.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 Jan.1,2021.Published January 2021.Originallyapproved in 1984.Last previous edition approved in 2016 as D1370/D1370M 12(2016).DOI:10.1520/D1370_D1370M-12R21.2This 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.16.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
