……………………………………… (sampling and assaying guidance below is optional) ……………………………..
Open all containers, making note of any different markings, forms or indications of heterogeneity or contamination.
If there are not indications of material heterogeneity then sample on an incremental basis in accord with the producers cast size, generally a lot size of 2.4 I 3.8 MT (*) or as advised by the producer. If heterogeneity is suspected select the incremental groups accordingly but in sublots of (*) or less. Tip 10% of the open drums and make a quantitative size estimation of the material say in to three fractions:- > 80 mm, 10 mm to 80 mm, and < 10 mm. Using the appropriate ISO shovel draw take 3 increments from each of the tipped drums, into a sealable container to give a bulk sample. With a bulk sample for each sublot, where heterogeneity or contamination is suspected it may be considered necessary to segregate certain drums and prepare samples separately.
The bulk samples can then be mixed by coning and quartering to produce final quality samples. Where considered desirable each sub lot can be treated to produce an individual bulk sample which can either all contribute to give a composite sample or be treated individually to give a series of quality samples.
The balance of the bulk samples being held for reference purposes.
It may be necessary to employ drilling of individual pieces to obtain a suitable sample, using tungsten carbide tipped drills at 600/700 rpm.
