5、 appropriatesolvent bearing asphaltic compounds.1.1.2 Coal-tar-saturated cotton fabric shall be used withcoal-tar based plying cements; a typical one is coal-tar pitchconforming to Specification D450 or appropriate solvent bear-ing coal-tar compounds.1.2 The values stated in either SI units or inch-
6、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.

9、ocess of manufacture, the dry cotton fabric shallbe thoroughly and uniformly saturated with bitumen. This shallbe accomplished by passing the fabric through the saturant orby spraying with saturant, calendering in the presence of heat,and then cooling before winding on a core.4.2 If fabric with a se
10、lvage is used, the selvage shall not bemore than 16 mm 58 in. wide.4.3 The fabric shall be woven entirely from cotton fibers,but customary sizing materials not exceeding 8 % by weight ofthe moisture-free cotton shall be permitted to be used.5. Physical Properties5.1 The material shall conform to the
11、 physical requirementsprescribed in Table 1 and the dimensions and masses pre-scribed in Table 2.5.2 The finished product shall not crack nor be so sticky asto cause tearing or other damage upon being unrolled attemperatures between 10 and 60C 50 and 140F.6. Workmanship, Finish, and Appearance6.1 Th
12、e meshes of the fabric shall not be completely closedor sealed by the process of saturation. There shall be sufficientporosity maintained to allow successive moppings of theplying cement to seep through.1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing a

Sampling and Test Methods7.1 Sample the material and determine compliance withthese specifications in accordance with Test Methods D146.7.2 Determine the pliabilit
17、y of the saturated fabric at 0C32F by bending over a 1.6-mm 116-in. diameter mandrelthrough an arc of 180 in one direction and then through 360in the opposite direction.7.3 Determine the thread count in accordance with TestMethod D3775.8.
