Formation of batches The formation of batches shall be as follows: A batch shall consist of a group of products of 2000 kg or under poured the metal from the same ladle. In the case where a product exceeds 2000 kg, one piece of product shall be
21、considered to be one batch. In the case where it is operated continuously in the same furnace of the same charging ratio, the tapped quantity within successive 2 h may be con- sidered to be one batch. When the molten metal tapped from 2 or more furnaces has been collected in a ladle, this shall be c
22、onsidered to be one batch. Notwithstanding the requirements of (i), several batches may be combined into one group, and any single batch among those may be allowed to repre- sent the said group by agreement between the purchaser and supplier. In this case, however, those batches shall be verified th

Test sample The test sample shall be as follows: Separately cast test sample Separately cast test sample shall be poured under the same conditions as the iro
24、n casting for each one batch by using, as a rule, a comparable mould. The number of the test samples shall be one piece excluding spare ones. In the case where the iron castings are subjected to heat treatment, the test sample shall also be subjected to heat treatment in the same manner. The mould k

Retest The retest shall be as follows: (i) When judged that the flaw or cavity of the test piece has affected adversely on test results, the te
33、st shall be deemed as invalid, and a retest may be carried out by using the spare test piece. In the case where a part of the results of the mechanical tests does not conform to the requirements caused by another reason than that given in (i), the retest may be carried out on the test item(s) not co
34、nforming to the requirements by using the spare test pieces. In this case, the number of the test pieces shall be two times the number of the test pieces of 9.5.1. In addition, all of the results of the retest shall conform to 5. (2) 11. Inspection The inspection of the iron casting shall be as foll
