Scope

WARNING: Personnel using this standard should have practical experience in formal laboratory work. This standard does not address all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with relevant national regulations. This standard specifies the test method for evaluating the difficulty of oxygen removal from iron ore by measuring the reduction index, final reduction degree and metallization rate under the condition of direct gas reduction. This standard applies to lump ore and pellets.
