Materials and Manufacture4.1 In the process of manufacture, a single thickness of dryfelt shall be saturated with refined coal-

8、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 splitting or tearing on thebias, the felt shall appear reasonably free of lump

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 other damage upon being unrolled attemperatures between 10 and 60C 50 and 140F

10、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 theirfull length.6.2 The surface of the felt shall not be coated or coveredwith talc

11、 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, cracks,tears, protuberances, and indentations.7.
