    Significance and Use

    4.1 These test methods for the chemical analysis of metals and alloys are primarily intended as referee methods to test such materials for compliance with composition specifications. It is assumed that all who use these 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 chemical analysis of copper alloys having chemical ranges within the following limits:2
