THE USE OF UV ACTIVATED OZONE FOR THE CLEANING OF PRIMARY PLATINUM-IRIDIUM KILOGRAM MASS STANDARDS

Stuart Davidson
  • Abstract:
    The cleaning of primary platinum-iridium mass standards is traditionally achieved using the nettoyage-lavage process developed at the BIPM. This manual cleaning method is notoriously difficult to reproduce, particularly at laboratories other than the BIPM. An alternative, operator independent, method for the cleaning of primary mass standards, using UV activated ozone, has been investigated and the results are reported.
