Sampling14.1 SamplingThe lot size, portion size, and selection ofsample pieces shall be as follows:14.1.1 Lot Size40 000 lb (18 144 kg) or less material ofthe same mill for
29、m, temper, and thickness, subject to inspectionat one time.14.1.2 Portion SizeSample pieces shall be selected fromeight individual pieces, and shall be taken so as to berepresentative of those pieces. If the lot consists of less thaneight pieces, a sample shall be taken from each individualpiece.14.
30、2 Chemical Analysis:14.2.1 The sample for chemical analysis shall be taken inaccordance with Practice E 255 for product in its final formtaken from the pieces selected in 14.1.2 and combined into onecomposite sample. The minimum weight of the compositesample shall be 150 g.14.2.2 Instead of sampling
31、 as directed in 14.2.1, the manu-facturer shall have the option of sampling at the time thecastings are poured or samples taken from the semifinishedproduct. If the manufacturer determines the chemical compo-sition of the material during the course of manufacture, he shallnot be required to sample a
32、nd analyze the finished product.14.2.2.1 When samples are taken at the time the castings arepoured, at least one sample shall be taken from each group ofcastings poured from the same source of molten metal.14.2.2.2 When samples are taken from semifinished prod-uct, a sample shall be taken to represe
