| Summary | This standard specifies a method for the determination of iron oxide in catalytic cracking catalysts by o-phenanthroline spectrophotometry. This standard applies to catalytic cracking catalysts, catalytic cracking catalysts and additives to improve the yield of low carbon olefins and gasoline octane. The precision of this standard is established in the range of 0.25% to 0.71% of the iron oxide mass fraction. This standard can be measured beyond this range, but the precision is not established. |
