36、od of seven years.8.5 Copies of the coating test shall be furnished whenrequested.9. Sampling9.1 Chemical and mechanical tests shall be made regularlyand at sufficiently close intervals for adequate determinationsof the significant chemical constituents and properties of thecast iron. A specimen tak
37、en from a finished product often doesnot produce the same results as a specimen formed by themethod used for sample preparation and is not acceptable forthe purpose of testing to this standard. Records of chemicalanalysis shall be maintained by the manufacturer by lot. Copiesof these analyses shall
38、be furnished to the purchaser whenrequested.9.2 A lot shall consist of one of the following:9.2.1 All the metal poured from a single heating in abatch-type furnace.9.2.2 All the metal from two or more batch-type meltingfurnaces poured into a single ladle or a single casting.9.2.3 All the metal poure
