Measurement Standards for Mass & Related Quantities
Mass Artifact (Cleaning, Atmosphere, Magnetism)
Density (Si, Water,Tri-decane, Mercury,)
Force (Load Cell, Torque)
Pressure (Piston Gauge:Deformation,
Low-P operation., Manometry:,
Silicon Vac. Gauge, Spinning Rotor Sensor)
Hardness (Ideal Procedure for Hardness Testing.)
:Improvement of Global Measurement Standards
Density, Lattice Spacing, Molar Mass, Defect
Redundancy: NA 2-3x10-7, Discrepancy 5x 10-7
