1、Designation: D1370/D1370M 12 (Reapproved 2016)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
2、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
3、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
4、 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
5、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.

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. Si
7、gnificance 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
8、, 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 tem
9、perature 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.NOTE 1When this test method
10、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.6. Procedure6.1 Melt a portion of the coating at the minimum tempera-ture required to render it fluid, stirring with the fine
11、wire toeliminate bubbles, and pour it into the clean 85-g 3 oz tin lidto a thickness of 3.0 to 6.0 mm 18 to14 in. 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

Form the drops by plunging the wire into the moltensaturant and, after the excess has drained off, allowi
19、ng suitablysized drops to fall on the talc from a sufficient height to formsubstantially spherical drops.6.5 Place the prepared specimen in the test oven, so regu-lated as to maintain the specimen at the recommended testtemperature, within 61.0C 61.8F, for 72 h (Note 2). Aftercooling, examine the sp

Measure the width from the line of contactof talc and drop to the outer limit of the oil ring.NOTE 2The recommended test temperature for roofing materials is50C 122F, but this may be al
