Newly available analytical data on iron‐formation reference samples are combined with values published earlier, in order to test the effectiveness of a revised version of the ‘five‐mode” method of evaluation, with the well‐established sample IF‐G as reference. The same method is then applied to improve the earlier evaluation of samples FeR‐1, ‐2, ‐3 and ‐4. The resulting values are compared with those in the original evaluations. Better results are obtained than were possible with earlier versions of the method, but some problems do persist.
