Sampling & Assaying Norms
It is a truism of the metal trade that professional methods of sampling a metal are as important as the quality of the resulting chemical analysis. Sworn samplers have a code of practice and rules but instructions from the payee are very important in determining whether the results obtained are fully representative. Most metals and scraps have various idiosyncracies that mean that a simple rule for all may not apply. It was with this in mind that the MMTA worked closely with a n umber of well known samplers and assayers to publish some guidance in this field. You will find these details listed according to the metal in question.
