【国外标准】 Standard Test Method for Determination of Crushing Strength of Iron Ore Pellets and Direct-Reduced Iron

5.1 The crushing strength aids the pellet producer in the determination of quality problems associated with the production of pellets.5.2 The crushing strength is often used by the pellet consumer as a quality indicator for performance in the blast furnace and gas-based direct reduction plants.1.1 This test method describes a method for determining the crushing strength of fired iron ore pellets and direct-reduced iron. Cylindrical agglomerates and briquettes are not covered by this test method.1.2 The values as stated in SI units are to be regarded as the standards. The values in parentheses are given for information only.1.3 Results given by this test should be similar to those from ISO 4700 (see Appendix X1 for details).1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
