The International Temperature Scale 1990 (ITS-90) is the current internationally recognized temperature scale in use worldwide. After the redefinition of the kelvin via the Boltzmann constant, the ITS-90 will continue to be used as a robust and reliable tool. However, it has some limitations and pending issues that need to be resolved.
Objectives
Development of new advanced techniques to improve the traceability of the current definition of the kelvin, before the redefinition of 2018
Establish traceability to the SI according to the new definition, in order to support the widest and simplest dissemination of the temperature unit to end users
