Copper Standard Reference Materials (Benchmark Series)

Source

The Standard Reference Materials Program has experienced increasing demands for new kinds and types of standard materials. In order that the largest number of users be served by these materials and the available resources be used to best advantage, careful planning is required. The planning process helps to ensure that, among other factors, the fewest number of different materials will be produced, a wide range of needs will be met, and production and certification can be accomplished at a level consistent with the intended uses. One output of this process has been the concept of “Benchmark Series” SRMs. These are usually a set of similar materials with varying amounts of a number of elements covering a wide range of concentrations.

Largely through the auspices of ASTM Committee E-2 on Emission Spectroscopy, more than 70 persons from NBS, ASTM, and from throughout the copper industry contributed to the planning of a series of Copper Benchmark Standard Reference Materials. As a result, 12 different materials issued as chips, rods, and cast solids and representing as many as 25 different SRMs have been prepared and certified for as many as 29 elements. The production and certification process and the certified values for this important series are described and the certified values are given.
