NIST provides a wide range of reference materials to support accurate and comparable measurements across various industries. These materials are categorized into three main types:
1. NIST Standard Reference Materials (SRMs): These are certified reference materials that have been thoroughly tested and documented to ensure their quality and reliability. They are used as primary standards for calibration and quality control in various fields.
2. NIST Reference Materials: These are qualified reference materials that have been tested and documented to meet specific quality criteria, such as homogeneity and stability. They are used for quality control and assurance in various applications.
3. NIST Research Grade Test Materials: These materials are used for research and development purposes and have not been fully tested and documented like SRMs and Reference Materials.
NIST reference materials are available for purchase online at shop.nist.gov, and more information can be found in NIST Special Publication 260-136:2021. The materials are used across various industries to ensure accurate and reliable measurements, calibration, and quality control.
