3、-C-450.1. Scope1.1 This specification covers woven cotton fabrics saturatedwith either asphalt or coal-tar pitch intended to be used withasphalts conforming to Specifications D 312 or D 449, coal-tarpitches conforming to Specification D 450, or appropriatesolvent bearing bituminous materials in the

4、construction ofroofing and waterproofing systems.1.1.1 Asphalt-saturated cotton fabric shall be used withasphalt base plying cement; typical ones are mopping asphaltsconforming to Specifications D 312 or D 449 or appropriatesolvent bearing asphaltic compounds.1.1.2 Coal-tar-saturated cotton fabric s

Terminology3.1 DefinitionsFor definitions of terms used in this speci-fication, refer to Terminology D 1079.4. Material

8、s and Manufacture4.1 In the process 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

9、a core.4.2 If fabric with a selvage 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 T

10、he material shall conform to the 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. Workman

11、ship, Finish, and Appearance6.1 The 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.6.2 The surface of the fabric shall not be coated or coveredwit

12、h talc or other substances that would tend to interfere withadhesion between the fabric and the plying cement. The use ofsilica or wood flour is permissible.6.3 The surface shall be uniformly smooth and free ofirregularities, folds, or knots.6.4 The finished material shall be free of visible externa

Sampling and Test Methods7.1 Sample the material and determine compliance withthese specifications in accordance with Test Methods D 146.7.2 Determine the pliabi

16、lity of the saturated fabric at 0C(32F) 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 D 3775.8. Inspection8.1 InspectionInspection shall be in accord

17、ance with therequirements of this specification.8.2 Inspection AlternativesAlternative inspection require-ments shall be determined by and agreed upon between thepurchaser and the supplier.9. Rejection and Resubmittal9.1 Failure to ConformFailure to conform to any of therequirements as stated in thi

18、s specification constitutes groundsfor rejection.9.2 Rejection RedressThe supplier shall have the right toinspect the rejected materials. The supplier and the purchasershall agree to the quantity of rolls deemed unacceptable. Thesupplier shall then have the right to submit the same number ofnew roll

19、s as replacement.10. Packaging and Package Marking10.1 Unless otherwise agreed upon between the supplierand purchaser, each product package shall be plainly markedwith the suppliers name, the product brand, the ASTMdesignation, and type of bitumen if not evident in the labelname of the product.10.2

20、The rolls shall be securely wrapped or banded in amanner that completely encircles the roll and will preventslipping or unrolling.10.3 No roll shall contain more than two pieces, and nomore than 3 % of the rolls in any lot shall contain two pieces.If a roll contains a manufacturing splice, the splic

21、e shall beclearly marked.10.4 The rolls shall be wound on mandrels or rigid hollowfiber cylinders not less than 50 mm (2 in.) in diameter,extending not more than 100 mm (4 in.) beyond the end of therolls.11.
