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

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.
