Standard Practice for Sampling Wrought Nonferrous Metals and Alloys for Determination of Chemical Composition

Standard Practice for Sampling Wrought Nonferrous Metals and Alloys for Determination of Chemical Composition

SCOPE
1.1 This practice covers the sampling, for the determination of chemical composition (Note 1), of nonferrous metals and alloys that have been reduced to their final form by mechanical working; that is, by such means as rolling, drawing, and extruding.
1.1.1 Refer to Practice E255 for copper and copper alloys.
Note 1--The selection of correct portions of material and the preparation of a representative sample from such portions are necessary prerequisites to every analysis, the analysis being of no value unless the sample actually represents the average composition of the material from which it was selected.
1.2 In special cases, when agreed upon by the purchaser and the manufacturer, the heat analysis may be accepted as representative of the composition of the finished product. In such cases, the identity of each heat of metal should be maintained through each stage of the manufacturing process to the final form. This method of sampling is not intended to apply under these conditions.
1.3 The values stated in inch-pound units are to be regarded as the standard.
1.4 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.

Standard Practice for Sampling Copper and Copper Alloys for the Determination of Chemical Composition

SIGNIFICANCE AND USE
4.1 This practice is intended primarily for the sampling of copper and copper alloys for compliance with compositional specification requirements.  
4.2 The selection of correct test pieces and the preparation of a representative sample from such test pieces are necessary prerequisites to every analysis. The analytical results will be of little value unless the sample represents the average composition of the material from which it was prepared.
SCOPE
1.1 This practice describes the sampling of copper (except electrolytic cathode) and copper alloys in either cast or wrought form for the determination of composition.  
1.2 Cast products may be in the form of cake, billet, wire bar, ingot, ingot bar, or casting.  
1.3 Wrought products may be in the form of flat, pipe, tube, rod, bar, shape, or forging.  
1.4 This practice is not intended to supersede or replace existing specification requirements for the sampling of a particular material.  
1.5 The values stated in SI units are to be regarded as standard. The values in parentheses are given for information only.  
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement appears in Appendix X4.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Sampling Wrought Nonferrous Metals and Alloys for Determination of Chemical Composition

ABSTRACT
This practice covers the sampling, for the determination of chemical composition of nonferrous metals and alloys that have been reduced to their final form by mechanical working; that is, by such means as rolling, drawing, and extruding. The portion selection, sample preparation, sampling details, sample size and storage, and resampling are also detailed.
SCOPE
1.1 This practice covers the sampling, for the determination of chemical composition (Note 1), of nonferrous metals and alloys that have been reduced to their final form by mechanical working; that is, by such means as rolling, drawing, and extruding.  
1.1.1 Refer to Practice E255 for copper and copper alloys.  
Note 1: The selection of correct portions of material and the preparation of a representative sample from such portions are necessary prerequisites to every analysis, the analysis being of no value unless the sample actually represents the average composition of the material from which it was selected.  
1.2 In special cases, when agreed upon by the purchaser and the manufacturer, the heat analysis may be accepted as representative of the composition of the finished product. In such cases, the identity of each heat of metal should be maintained through each stage of the manufacturing process to the final form. This method of sampling is not intended to apply under these conditions.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Analysis of Low-Alloy Steels by Wavelength Dispersive X-Ray Fluorescence Spectrometry

SIGNIFICANCE AND USE
5.1 This test method is suitable for manufacturing control and for verifying that a product meets specifications. This test method provides rapid, multi-element determinations with sufficient accuracy to ensure product quality and to minimize production delays. The analytical performance data may be used as a benchmark to determine if similar X-ray spectrometers provide equivalent precision and accuracy, or if the performance of a particular X-ray spectrometer has changed.  
5.2 Calcium is sometimes added to steel to affect inclusion shape which enhances certain mechanical properties of steel. This test method is useful for determining the residual calcium in the steel after such treatment.  
5.2.1 Because calcium occurs primarily in inclusions, the precision of this test method is a function of the distribution of the calcium-bearing inclusions in the steel. The variation of determinations on freshly prepared surfaces will give some indication of the distribution of these inclusions.
SCOPE
1.1 This test method covers the wavelength dispersive X-ray fluorescence analysis of low-alloy steels for the following elements:    
Element  
Mass Fraction
Range, %  
Calcium  
0.001 to 0.007  
Chromium  
0.04 to 2.5  
Cobalt  
0.03 to 0.2  
Copper  
0.03 to 0.6  
Manganese  
0.04 to 2.5  
Molybdenum  
0.005 to 1.5  
Nickel  
0.04 to 3.0  
Niobium  
0.002 to 0.1  
Phosphorus  
0.010 to 0.08  
Silicon  
0.06 to 1.5  
Sulfur  
0.009 to 0.1  
Vanadium  
0.012 to 0.6  
1.1.1 Unless exceptions are noted, mass fraction ranges can be extended and additional elements can be included by the use of suitable reference materials and measurement conditions. Deviations from the published scope must be validated by experimental means. See Guide E2857 for information on validation options.  
1.2 The values stated in the International System of Units (SI) are to be regarded as standard. The values given in parentheses are mathematical conversions to other units that are provided for information only, because they may be used in older software and laboratory procedures.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 10.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
