All industrial sectors rely on elemental analysis and physical properties testing to confirm product compliance with manufacturing specifications. Support of product compliance testing has long been a core activity in the Chemical Sciences Division in collaboration with industry associations and standards developing organizations (SDOs). For years, the Chemical Sciences Division has invested in development of standard test methods for industrial commodities and in SRM development to validate those methods and to establish traceability to the International System of Units (SI). These efforts are aligned with industry needs through interaction with SDOs, industry associations, expert private sector laboratories, and commercial reference materials producers.
In the arena of industrial commodities, the primary challenges are to provide measurement tools and reference materials that allow U.S. industry to establish comparability of measurement results to results obtained by customers, competitors, and regulators for the basic chemical properties of products, intermediates, and by-products on a worldwide basis. All members of a given industrial supply chain benefit from critically evaluated standard test methods validated using trusted reference materials. The private sector can leverage NIST reference materials for key commodities by creating their own reference materials targeted at products having more specialized compositions and applications.
The goals of this program are to:
In the past several years, the following SRMs have been developed or renewed in collaboration with industry:
The following industry standard methods of test were developed and approved with significant contributions by NIST.
This program is comprised of a number of collaborations between NIST and industry sectors. Design of materials for new SRMs is accomplished in cooperation with materials and analysis experts from industry. Specifications for composition, homogeneity, and quantity are based on current and projected industry needs. Value assignment projects are designed to include high-performance analytical methods at NIST, state-of-the-art laboratory methods in industry, and classical chemistry methods where available and appropriate.
In addition, NIST is actively building relationships among manufacturers, their customers, and accreditation bodies. Through presentations at technical meetings and workshops at NIST and accrediting body events, NIST and our partners are working to educate everyone at the intersection of chemical metrology, quality system accreditation, manufacturing specifications, and regulations.
