ASTM E1277-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Terminology
3.1 For definitions of terms used in this test method, refer to Terminology E135.
4. Summary of Test Method
4.1 The sample is dissolved in mixed acids. The sample solution is introduced into the plasma source of an ICP spectrometer and
the intensities at selected wavelengths from the plasma emission spectrum are compared to the intensities at the same wavelengths
measured with calibration solutions.
5. Significance and Use
5.1 This test method for the chemical analysis of metals and alloys is primarily intended to test such materials for compliance with
compositional specifications. It is assumed that all those who use this test method 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.
