出版：British Standards Institution
專家解讀視頻
Establishes two methods for determining ash from raw rubbers, compounded rubbers and vulcanizates. Applicable to raw, compounded or vulcanized rubbers of the M, N, O, R and U families. Does not cover the interpretation of the ash results as to the inorganic chemical content of a compound or vulcanizate. Method A shall not be used for determining ash from compounded or vulcanized rubbers containing chlorine, bromine or iodine. Method B shall not be used for uncompounded rubbers. The two methods of ashing do not give identical results in all cases, and it is necessary to state in the test report the method of ashing employed.
