Product Analysis
1 An analysis of either one billet or one length of flat-rolled
stock or one tube shall be made from each heat. The chemical
composition thus determined shall conform to the
requirements specified.
2 A product analysis tolerance (see the annex table on Chemical
Requirements (Product Analysis Tolerances) in SpecificationA 480/A
480M) shall apply. The product analysis
tolerance is not applicable to the carbon content for material with
a specified maximum carbon of 0.04 % or less.
3 If the original test for product analysis fails, retests of two
additional billets, lengths of flat-rolled stock, or tubes shall be
made. Both retests for the elements in question shall meet the
requirements of this specification; otherwise, all remaining
material in the heat shall be rejected or, at the option of the
producer, each billet or tube may be individually tested for
acceptance. Billets, lengths of flat-rolled stock, or tubes that do
not meet the requirements of this specification shall be rejected.
