Inspection Schedule
Open all containers, note any different markings or indications of heterogeneity or contamination.
Sampling Schedule
If there are no indications of material heterogeneity then sample on an incremental basis of 500 KG sublots. If heterogeneity is suspected select the incremental groups accordingly. Using the appropriate auger draw samples from three places from each drum, to the full depth. Mix and reduce the increments by coning and quartering to secure a bulk sample in a sealed container.
Sample Preparation
The bulk samples after careful mixing can either be composited for the parcel, or treated individually, and quality samples drawn. The moisture level should also be checked.
The balance of any bulk samples should be kept.
