NIST has characterized two large diameter (35.8 mm) piston/cylinder assemblies as primary pressure standards in the range 0.05 MPa to 1.0 MPa with uncertainties approaching the best mercury manometers. The realizations of the artefacts as primary sta

Solubility and deposition rate experiments were performed in aqueous sodium sulfate and potassium sulfate solutions at elevated temperatures and pressures typical of the supercritical water oxidation (SCWO) process. The test cell was a six-port chamb

Primary pressure standards in the atmospheric pressure range are often established using mercury manometers. Less frequently, controlled-clearance dead-weight testers in which one component (normally the piston) has been dimensionally measured have a
