ASTM E118 Standard Test Methods for Chemical Analysis of Copper-Chromium Alloys (Withdrawn 2010)
ASTM E118 has given standardized test procedures for chemical analysis of copper-chromium alloy, including procedures involved in determining the concentration of chromium and other elements using classical methods of wet chemistry. Even after this standard was dropped officially in 2010, it had an important role in ensuring the quality and consistency of copper-chromium alloys that were applied for electrical, thermal, and structural purposes. They found applications in quality control, alloy check, and metallurgical research, where they were later replaced by or superseded by modern instrumental techniques. The techniques assisted with services of alloy certification, quality monitoring in production, and copper-based high-performance products research.

ASTM E118 Introduction
ASTM E118 specified classical procedures of chemical analysis to determine chromium content and other potential impurities. Copper-chromium Alloys have high electrical and thermal conductivity, as well as better mechanical strength. In electrical contacts, welding electrodes, heat-resistant components, etc., an exact chemical composition is essential to have the intended properties. Such techniques, gravimetric or volumetric, avoided errors and made a control action within the industrial sector reproducible before the development of present-day instrumental methods, e.g., atomic absorption spectroscopy (AAS) or inductively coupled plasma (ICP).
