Significance and Use | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these test methods will be trained analysts, capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory. |

1. Scope | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1.1 These test methods cover the
determination of carbon, sulfur, nitrogen, and oxygen, in steel and
in iron, nickel, and cobalt alloys having chemical compositions
within the following limits:
1.2 The test methods appear in the
following order:
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. Specific hazards statements are given in Section 6. 10.1 This test method covers the determination of carbon in concentrations from 0.005 % to 4.5 %. 21.1 This test method covers the determination of sulfur in the range of 0.001 % to 0.01 %. As written, this test method is not applicable to cast iron samples. 32.1 This test method covers the determination of nitrogen (N) in concentrations from 0.0010 % to 0.2 % (Note 12). Note 12—The upper limit of the scope has been set at 0.2 % because sufficient numbers of test materials containing higher nitrogen contents were unavailable for testing in accordance with Practice E 173. However, recognizing that commercial nitrogen determinators are capable of handling higher concentrations, this test method provides a calibration procedure up to 0.5 %. Users of this test method are cautioned that use of it above 0.2 % is not supported by interlaboratory testing. In this case, laboratories should perform method validation using reference materials. 43.1 This test method covers the determination of oxygen in the range 0.001 % to 0.005 % in steel. Note 22—The upper limit of the scope has been set at 0.005 % because sufficient numbers of test materials containing higher oxygen contents were unavailable for testing in accordance with Practice E 173. However, recognizing that commercial oxygen determinators are capable of handling higher concentrations, it may be that this test method can be used for oxygen concentrations outside of the scope. In this case, laboratories should perform method validation using reference materials. Users of this test method are cautioned that use of it above 0.005 % is not supported by interlaboratory testing. 55.1 These test methods cover the determination of sulfur in the range of 0.002 % to 0.35 %. |
