About this file
This document is an Attachment D to a solicitation, containing the NIST Handbook 105-3 Volumetric Field Standard Specification Checklist. It outlines the evaluation criteria and requirements for volumetric field standards used in weights and measures applications. The checklist covers identification markings, construction materials, shape and design, scale plate requirements, and other technical specifications. It also addresses non-retroactive requirements for sight flow indicators, bleed lines, and vapor recovery systems. The document provides guidelines for evaluating the suitability of volumetric field standards for weights and measures usage.
The checklist covers 40 specific evaluation criteria across categories such as identification, construction, scale plate, support, drainage, and workmanship. Each requirement is referenced to the applicable section in NIST Handbook 105-3, and the evaluator must indicate whether the standard meets the requirement or is rejected, or note if the requirement is not applicable. Comments can be provided to explain any rejections or special application exemptions.
