31. A High Accuracy Micrometer for Diameter Measurements of Cylindrical Standards
John Richard Stoup, Theodore D Doiron
NIST has developed a new instrument to measure cylindrical standards including thread wires and plain plug gages. The instrument uses a laser interferometer system which is coupled with an air bearing linear motion slide and precise contact geometry ...
32. CCM Key Comparison in the Pressure Range 0.05 MPa to 1 MPa (Gas Medium, Gauge Mode) - Phase A1: Dimensional Measurements and Calculation of Effective Area
G F Molinar, B Rebaglia, A Sacconi, J C Legras, G P Vailleau, James W Schmidt, John Richard Stoup, D R Flack, W Sabuga, O Jusko
The results obtained by five laboratories in the determination of the effective areas of two gas-operated 10 cm^u2^ piston-cylinder assemblies from dimensional measurements carried out as part, called phase A1, of a key comparison in the pressure ran ...
