6、acture, a single thickness of dryfelt shall be saturated with refined coal-tar from which some ofthe more volatile constituents have been removed.4.2 The felt shall be produced principally from organicfibers or mixtures thereof. The surface of the felt shall beuniform and relatively smooth. Upon spl
7、itting or tearing on thebias, the felt shall appear reasonably free of lumps and particlesof foreign substances.5. Physical Requirements5.1 The material shall conform to the physical requirementsprescribed in Table 1.5.2 The finished product shall not crack nor be so sticky asto cause tearing or oth
8、er damage upon being unrolled attemperatures between 10 and 60C (50 and 140F).6. Workmanship, Finish, and Appearance6.1 The felt shall be saturated and shall show no unsaturatedspots at any point upon cutting 50-mm (2-in.) wide strips atrandom across the entire sheet and splitting them open to their
9、full length.6.2 The surface of the felt shall not be coated or coveredwith talc or other substances that would tend to interfere withadhesion between the felt and the plying cement.6.3 The finished material shall be free of visible externaldefects such as holes, ragged or untrue edges, breaks, crack

The materialshall be accepted or rejected on the basis of the retest.DThe moisture-free felt shall meet this requirement prior to saturation. Coal-tar-saturated felt cannot be thoroughly desaturated by any known means; only anapproximate value may be obtained through desaturation.EThe mass of the saturant shall be not less than 1.4 times the mass of the desaturated (unsaturated) dry felt.D227032
