(Practice)Standard Practice for Preparation of Disk Specimens of Steel and Iron for Spectrochemical Analysis by Remelting
Standard Practice for Preparation of Disk Specimens of Steel and Iron for Spectrochemical Analysis by Remelting
SIGNIFICANCE AND USE
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.

4. Summary of Practice
4.1 The sample of steel or iron is placed in a water-cooled copper crucible. The furnace is flushed with argon at a controlled
rate of flow. An arc is struck between the electrode and the sample material and is maintained until the melting is complete. The
molten specimen is allowed to solidify in the crucible in an argon atmosphere.After solidification, the specimen is removed from
the crucible and prepared for spectrochemical analysis.
4.2 Partial losses of some elements may be experienced during the preparationmelting of the disk specimen. This procedure,
if carefully followed, will provide consistent losses. Elemental losses can be determined by correlating the analysis of the charge
material with the spectrochemical analysis of the remelted specimen.
5. Significance and Use
