3 Sampling of each heat at the producer's plant
4 Sampling of a lot of ingots or pieces
5 Treatment of chips
Annex A (normative) Number of small ingots to be taken
        and number to be analysed
Annex B (informative) Methods for taking a sample of size
        N in a supply of M items
Annex C (informative) Formulae giving the number N of ingots
        or pieces to be taken to form the primary sample
Annex D (informative) Technical conditions for drilling
        and milling

Applies to ferronickel lots in ingot or piece form with a view to obtaining a representative laboratory sample for the determination of the chemical composition of the lot. A choice is to be made between a first procedure that can be applied at the producer's plant during casting or a second procedure that can be applied to lots as delivered at the buyer's premises. Includes two alternatives for sample taking (drilling and milling). Each party is entitled to participate in sampling operations.
