For sampling cadmium in slab form a minimum of twopieces shall be selected for shipments of 500 lb or less, threepieces for shipments of 500 to 1000 lb (227 to 454 kg), and oneadditional piece for each additional 1000 lb or part thereof. Forcadmium in ball or stick form a minimum of four pieces shallbe selected for shipments of 500 lb or less，six pieces forshipments of 500 to 1000 lb and two additional pieces for eachadditional 1000 lb or part thereof.
The selected pieces shall be cleaned to rid the surface ofextraneous material and then sawed，drilled,or milled,carebeing taken to avoid errors due to segregation within thepieces. The saw,drill，or cutter used shall be thoroughlycleaned. No lubricant shall be used in the operation,and thesawings, drillings, or millings shall be treated with a magnet toremove any particles of steel introduced in the taking of thesamples. Equal weights of the sawings， drillings，or millingsshall be taken from each piece sampled, and then combinedinto one sample and thoroughly mixed. The total sampleweight shall be not less than 300 g. In those cases where the cadmium involved is in someother shape or form that does not lend itself to any of the abovemethods, the sampling procedure shall be agreed upon betweenthe manufacturer or seller and purchaser. The method of 9.1offers many advantages.
