It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. If this heat analysis does not meet the heat analysis requirements of the specication, one sample from the product of each remelted ingot shall be analyzed, and the analyses shall meet the heat analysis requirements.

A — 07a Standard Test Methods, Practices, and Terminology for Chemical Analysis of Steel Products1 This standard is issued under the xed designation A a7511 the number immediately following the designation indicates the year of original adoption or, in the case of revision, s751 year of last revision.
It applies only to product analysis and becomes meaningful only when the heat analysis of an element falls close to one of the specied limits. Axtm June 1, The range of the specied composition applicable to product analysis is normally greater than that applicable to heat analysis in order to take into account deviations associated with analytical reproducibility Note 1 and the heterogeneity of the steel.
If the product analysis tolerance for such a chromium level is 0. NOTE 4—All commercial metals contain small amounts of various elements in addition to those which are specied. A number in parentheses indicates the year of last reapproval.
The analysis shall meet the specied limits for heat analysis. Unspecied Elements Note 4 7. The results of such analyses shall conform to the requirements specied in the material specication. See Table 1 for asttm elements and ranges for stainless steels. Last previous edition approved in as A — It is intended that these test methods, practices, and terminology will contain all requirements for the determination of chemical composition of steel, stainless steel, or related alloys so that product specications will need contain only special wstm and exceptions.
