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
