Note: In the event of conflict between the Korean and English language, the

3、Korean language shall take precedence. 1.1 Purpose. This standard shall be used for the determination of pure bitumen which is soluble in the extraction medium using the ratio of the loss in weight and the original weight of the test piece due to extraction. 1.2 Applicability. This standard shall be

4、 applied to paper, cardboard and similar materials containing bitumen as primary additive. 2 References Note: Only the latest approved standards are applicable unless otherwise specified. 2.1 External Standards/Specifications.
