1、Designation: D 1370 00 (Reapproved 2007)Standard Test Method forContact Compatibility Between Asphaltic Materials (OliensisTest)1This standard is issued under the fixed designation D 1370; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi
2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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.
3、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 SI units are to b

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and

Summary of Test Method3.1 A small drop of molten saturant is placed on the freshlytalced surface of the coating, and compat
6、ibility 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-pat

Talc fromLuzenac America, Inc.4has been found to be suitable for this test.6. Procedure
10、6.1 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 mm(18 to14 in.). Pour carefully, soas to provide a substantially smooth surface free
11、of bubbles andother surface blemishes. After the coating material has cooled,determine the weight and surface area of the filled container.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
12、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 (34 to 1 in.) above the surface of1This test method is under the jurisdiction ofASTM Committee D08 on Roofingand Waterproofing and is the direct responsibility of S
