Abstract:

This guide presents information that will assist with establishing traceability to the primary relations of the redefined kilogram, i.e. watt balance and X-ray crystal density (Avogadro) experiments. The guide gives information on the establishment of weighing-in-vacuum facilities and on methodologies to achieve traceability from the realisation of the kilogram in vacuum to weights stored and used in air.
