New Practice for Contents of Documentation and Statistical Treatments for Reference Materials for Metals, Ores, and Related Materials

1. Scope

To prepare, evaluate, and issue test methods, practices, guides, and terminology for chemical and spectrochemical analysis as they apply to sampling and testing of metals, ores, and related materials; other practices including interlaboratory testing and statistical evaluation; physical testing of refractories and liaison with other ASTM Committees, especially those which write specifications.
The Committee shall promote knowledge and stimulate research in analytical chemistry for metals, ores, and related materials. The work of the Committee shall be coordinated with other ASTM Committees and other organizations having mutual interests.

The metals and mining industries need their own, specific practices and guidance for development and value assignment of reference materials, because ISO 17034 and the Guide 30 series do not provide detailed procedures to enable reference materials producers, who support these industries, to develop and market RMs that are of sufficiently high quality to meet industry needs for test method validation. Numerous RM products do not provide the information needed, and the approaches taken by RM producers to documentation are diverging at an increasing rate. Many certificates of analysis contain confusing and even incorrect language and information. Reference material producer members of Committee E01 support this activity. They will use the practice to improve their products and associated documentation. Industry laboratories will get better values and uncertainty estimates to improve the accuracy of test methods. They will also get more consistent language and definitions for the contents of Rm documents. Quality system accreditation activities will become more consistent and better targeted to chemical metrology, saving everyone time and money.

The title and scope are in draft form and are under development within this ASTM Committee.
