1. For each grade of K8-11 (ie. K8-11C; K8-11HA & K8-11B) we need to know the batch size( total Kg per batch) and therefore the total number of drums per unique batch. We need this to advise SGS on the number of drums they need to sample per unique bath in order to produce the composite batch sample. Some of the batch sample will be sent to the UK and some should be used by SGS in conjunction with your QC analyst to measure the Bulk Density of the batch at your QC labs.
