(Practice)Standard Practice for Preparation of Disk Specimens of Steel and Iron by Remelting for Spectrochemical Analysis (Withdrawn 2022)
Standard Practice for Preparation of Disk Specimens of Steel and Iron by Remelting for Spectrochemical Analysis (Withdrawn 2022)
SIGNIFICANCE AND USE
5.1 Most spectrochemical instruments employed for analyzing steel and iron require a solid specimen with a flat surface large enough for analytical excitation and measurement procedures. This practice describes a procedure for converting unusual types of steel and iron samples to satisfactory spectrochemical specimens.
SCOPE
1.1 This practice describes the preparation of disk specimens of steel and iron by melting chunks, chips, drillings, turnings, wire, or powder briquets with an electric arc in an argon atmosphere. Solidification of the specimen takes place in the crucible in an argon atmosphere. The disk obtained is suitable for quantitative spectrochemical analysis.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Specific warning statements are given in 6.2.1, Section 8, and 10.1.2.1.
WITHDRAWN RATIONALE
This practice describes the preparation of disk specimens of steel and iron by melting chunks, chips, drillings, turnings, wire, or powder briquets with an electric arc in an argon atmosphere. Solidification of the specimen takes place in the crucible in an argon atmosphere. The disk obtained is suitable for quantitative spectrochemical analysis.
Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, this practice was withdrawn in June 2022 and replaced by Practice E1306 for Preparation of Metal and Alloy Samples for Chemical Analysis by Electric Arc Remelting.1
