Abstract:	This paper compares the equivalency of calibration and proficiency testing results between the two most common calibration procedures for large volume. National proficiency test have been coordinated among NIST and the State Weights and Measures Laboratories at 5 gal, 15 gal, and 100 gal. This paper covers: a summary of national capabilities in volume calibrations between 5 gal and 100 gal; equivalence of measurement results from gravimetric and volume transfer calibrations, including procedure review and troubleshooting checklists; uncertainty components and differences between the two methods; and lessons learned from participating and coordinating proficiency testing.
