40、uch analysis shall be furnished to the purchaser.7. Product Analysis7.1 When requested on the purchase order, a product analysis shall be made by the supplier. The number and source of samplesfor such product analysis shall be based on the individual heat or lot identity of one of the following form

42、and under.7.2 Samples for product analysis except for spectrochemical analysis shall be taken in accordance with Practice A751. Thecomposition thus determined shall correspond to the requirements of Tables 1 and 2.7.3 If the original test for product analysis fails, retests of two additional lengths
43、 of flat-rolled stock or tubes shall be made. Bothretests for the elements in question shall meet the requirements of the specification; otherwise, all remaining material in the heator lot shall be rejected or, at the option of the producer, each length of flat-rolled stock or tube may be individual
44、ly tested foracceptance. Lengths of flat-rolled stock or tubes which do not meet the requirements of the specification shall be rejected.8.
