QCRM-4-057 is a certified reference material which is suitable for use as random control samples in routine analytical laboratory quality control, when inserted within a batch of samples and measured in parallel to the unknown. The QCRM can also be used as a control sample in the analysis of samples of a similar type, verification of analytical methods for iron ore and as a calibration standard for the calibration of equipment used for analyzing similar materials.

Section 6 of the COA was amended to reflect the preparation of samples to 106-micron, as per the recommendation of ISO 3082:2017. The particle size was previously erroneously stated as 75-micron.
