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. 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. 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.
See Table 2 for normal elements and ranges for stainless steels.
NIST does not produce reference standards suitable for all elements or all alloys. Examples of denitive analytical methods include gravimetric, coulometry, titrimetric based on normality, and mass spectrometry.
This standard has been approved for use by agencies of the Department of Defense. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. It does not apply to cast or heat analyses determined to show conformance to specied chemical limits. Several independent laboratories should be used for certication of these standards and their results statistically reviewed and merged. Unspecied Elements Note 4 7. See Table 1 for normal elements and ranges for stainless steels. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Approved April 1, No comments were found for ASTM A – 11 standard test methods, practices, and terminology for chemical analysis of steel products. Product Analysis Requirements 6. Concerning the Specication of Chemical Composition Requirements 4. 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.
Such subjects as denitions of terms and product check analysis variations tolerances required clarication. A — 07a Standard Test Methods, Practices, and 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.
A number in parentheses indicates the year of last reapproval.
It is neither practical nor necessary to specify limits for every unspecied element asfm might be present, despite the fact that the presence of many of these elements is often a75 determined by the producer. A heat that the producer reported as Proprietary methods are permissible provided the results are equivalent to those obtained from standard methods when applicable. 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.
XXXX or may be expressed as ppm 0. Normal elements and ranges for stainless steels are as follows: 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. Current edition approved June 1, Last previous edition approved in as A — It includes both wet chemical and instrumental techniques. 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.
