32、tion requirement, each heat or lotin a shipment shall be considered separately. All samples shallbe taken from finished part or material in the condition inwhich it is received, except that all protective surface treat-ments shall be removed before sampling. Sample material shallbe free from scale,
33、grease, dirt, and other foreign materials andshall be taken in such a manner as to prevent alteration of thechemical composition of the sample. Sampling shall be inaccordance with Practice E55for wrought material or PracticeE88for cast material, as applicable, insofar as practicable.6. Keywords6.1 c
