Zusammenfassung The article is part ob the Theo Murphy meeting issue ‘Towards implementing the new kelvin’ organised and edited by Graham Machin, Joachim Fischer, Peter Hänggi and Martin Trusler. In 2018 it is expected that there will be a major revision of the International System of Units (SI) which will result in all of the seven base units being defined by fixing the values of certain atomic or fundamental constants. As part of this revision, the kelvin, unit of thermodynamic temperature, will be redefined by assigning a value to the Boltzmann constant k. This explicit-constant definition will define the kelvin in terms of the SI derived unit of energy, the joule. It is sufficiently wide to encompass any form of thermometry. The planned redefinition has motivated the creation of an extended Mise en Pratique (“practical realisation”) of the definition of the kelvin (MeP-K), which describes how the new definition can be put into practice. The MeP-K incorporates both of the International Temperature Scales (ITS 90 and PLTS 2000) in current use and approved primary thermometry methods for determining thermodynamic temperature values. The MeP-K is a guide that provides or makes reference to the information needed to perform measurements of temperature in accord with the SI at the highest level. In this article, the background and the content of the extended second version of the MeP-K is presented.
