— Method A is applicable for the determination of the ash from raw rubbers.
— Method B is applicable for the determination of the ash from compounded or vulcanized rubbers.
The methods are not applicable for the determination of the ash from raw rubbers, compounded or vulcanized rubbers containing chlorine, bromine or iodine.
