Inspection Schedule
Open all containers, note any different markings or indications of heterogeneity or contamination. Opening all the containers may well be impractical, alternatively open at least the number of drums for a 10 MT parcel, increasing by a 20% of that number for each subsequent sub lot of 10 MT. That is to say [N + 20% N/2] drums for 20 MT, [N + 20% N/3] drums for 30 MT, etc.
Sampling Schedule
If there are no indications of material heterogeneity then sample on an incremental basis of 10 MT sublots. If heterogeneity is suspected select the incremental groups accordingly but in sublots of 10 MT or less. Tip 10% of the opened drums and using the appropriate shov-el take samples top middle and bottom. The increments for each sublot should be mixed and an appropriate sample selected with each individual piece being drilled, taking the nec-essary precautions, and placed in an argon flushed container. All opened drums must be refilled with argon and resealed after inspection and sampling.
Sample Preparation
The drillings from each incremental sub lot should be mixed, drillings or pieces subdivided if necessary, to produce a homogeneous bulk sample in each instance.
Two options are then open:
(a) Quality samples can be drawn from each homogenised sub lot bulk sample for analysis.
(b) A composite can be prepared from portions of each of the sublots to give a total parcel bulk sample from which total parcel quality samples may be drawn.
The balance of the sub lots being held for reference purposes.
