BACKGROUND The National Institute of Standards and Technology (NIST) Office of Reference Materials, in conjunction with the Inorganic Chemical Metrology Group (ICGM), is responsible for the production, development, and characterization of Standard Reference Materials (SRMs) to enhance chemical measurement comparability within the U.S. and provide a basis for comparability with other nations. This purchase is in direct support of the mission by providing the specialized material processing and packaging necessary to produce coal SRMs that meet strict homogeneity and stability requirements. It ensures that energy industry stakeholders have access to reliable standards for clinical, fuel, and environmental analyses. The National Institute of Standards and Technology (NIST) has twelve (12) 5-gallon buckets of bituminous coal [approximately 120 kg (240 lb.)] that require blending and spin-riffling into bottles for a renewal coal Standard Reference Material (SRM). The renewal coal material comes from old stock remaining from production of SRM 2692c. DESCRIPTION OF REQUIREMENT The goal of this project is to package the coal material so that it is ready for delivery to the NIST customer. The intention is to issue the coal material as a NIST SRM, and preparation of a bottled material with negligible heterogeneity (within the inherent limitations of heterogeneity in the processed coal matrix) is an important consideration. The specific objectives of this project require the entire lot of coal material to be blended homogeneously into equal sublots. Sublots shall be spin-riffled into a minimum of 2000 bottles and not-to-exceed 2500 bottles. The remaining portions that are not bottled shall be placed in bags with liners and shall be returne…
