Duration: 5 days.
Venue: NMISA Training Center, Building 4, CSIR Campus, Pretoria
The course provides fundamentals of volume determination using the gravimetric method, which is the standard method used by NMIs and accredited laboratories to calibrate volumetric standards. Calibration of volumetric standards by weighing distilled water that is contained or delivered (dispensed) by the instrument to be calibrated. Conversion of mass measurements to volume values using distilled water, and Z factors. Identifying the factors that affect volume measurements. Determination of a compensation factor required for the mass lost due to evaporation during calibration of small volume. Evaluation of measurement uncertainty in volume metrology.
