A superscript epsilon e indicates an editorial change since the last revision or reapproval. The selection of a laboratory to perform the referee analysis asm be a matter of agreement between the supplier and the purchaser.
Approved June 1, If signicant variations in heat or cast size are involved, a weighted average heat or cast analysis, based on the relative quantity of metal in each heat or cast, shall be reported. It is the responsibility of the user of this standard to establish adtm safety and health practices and determine the applicability of regulatory limitations prior to use. Product Analysis Requirements 6.
Unspecied Elements Note 4 7.
Normal elements and ranges for stainless steels are as follows: The heat analysis shall be obtained from one remelted ingot, or the product of one remelted ingot, from each primary melt.
ASTM A – 11 standard test methods, practices, and terminology for chemical analysis of steel products 0. It aims to see global authorities and organisations use their purchasing and policy influence to accelerate the adoption of low carbon vehicles around the world by stepping up production to satisfy growing demand. A product analysis of It includes both wet chemical and instrumental techniques.
Such subjects as denitions of terms and product check analysis variations tolerances required clarication.
Cast or Heat Analysis 5. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Several independent laboratories should be used for certication of ast standards and their results statistically reviewed and merged. Global organisations call on vehicle manufacturers to boost low carbon cars Jul.

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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
See Table 2 for normal elements and astmm for stainless steels.
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. NIST does not produce reference standards suitable for all elements or all alloys.

This standard has been approved for use by agencies of the Department of Defense. Chemical Concentration Up to 0. If several determinations of any element in the heat are made, they may not vary both above and below the specied range. Examples of denitive analytical methods include gravimetric, coulometry, titrimetric based on normality, and mass spectrometry. It does not apply to cast or heat analyses determined to show conformance to specied chemical limits.
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.
A — 07a Ast Test Methods, Practices, astj Terminology for Chemical Analysis of Steel Products1 This standard is issued under the xed designation A ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. 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 modications and exceptions.
No comments were found for ASTM A – 11 standard test methods, practices, qstm terminology for chemical analysis of steel products. It is neither practical nor necessary to specify limits for every unspecied element that might be present, despite the fact that the presence of many of these elements is often routinely determined by the producer.
If the product analysis tolerance for such a chromium level is 0. Customer comments No comments were found for ASTM A – 11 standard test methods, practices, and terminology for chemical analysis of steel products. Committee A01 has identied the location of selected changes to this standard since the last issue A — 01 that may impact the use of this standard.
If you feel that your comments have not received a aa751 hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
XXXX or may be awtm as ppm 0. See Table 1 for normal elements and ranges for stainless steels. Approved April 1, Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
The results of such analyses shall conform to the requirements specied in the material specication. Concerning the Specication of Chemical Composition Requirements 4. A number in parentheses indicates the year of last reapproval. 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 a571 reproducibility Note 1 and the heterogeneity of the steel.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. If this heat analysis does not meet the heat analysis requirements of the specication, one sample from q751 product of each remelted ingot shall be analyzed, and the analyses a7551 meet the heat analysis requirements.
