Standard Guide for Spectrometric Analysis of Reactive and Refractory Metals

Importancia y uso:

4.1 Test methods for chemical analysis of reactive and refractory metals are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use this guide 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 under appropriate quality control practices such as those described in ISO 17025.

4.2 This guide is intended to aid analytical chemistry laboratories in the analysis of reactive and refractory metals and their alloys when no specific standard test methods are available. The principles incorporated in this practice and Guide E2857 can be applied in laboratories that wish to validate and document non-standard test methods.

4.3 The analysis of reactive and refractory materials is typically performed by only a small number of laboratories. Few of these laboratories have analytical instrumentation in common for use in interlaboratory proficiency testing programs. This requires the use of within-laboratory developed test methods that vary between laboratories. It is intended that this practice will give general guidance to experienced personnel that will assist them in the development of a procedure that will meet their analytical objectives.
