s02 Dissemination of the redefined kelvin (DireK-T)

这个计画的目的是利用开尔文的重新定义，使用实际的主要测温方法来传播热力学温度。2019年5月的开尔文重新定义启动了一个全面的研究阶段，以实现和传播热力学温度，取代目前使用的ITS-90/PLTS-2000标度。该项目的进展超越了最先进的水平，通过：演示从4 K到300 K的开尔文传播;开发一个强大的框架，用于建立初级测温的可追溯性;致力于下一代初级测温到700 K

The aim of this project is to take advantage of the kelvin redefinition using practical primary thermometry approaches for the dissemination of thermodynamic temperature. The kelvin redefinition in May 2019 initiated a comprehensive research phase for the realisation and dissemination of thermodynamic temperature to replace the ITS-90/PLTS-2000 scales currently in use. This project progresses beyond the state of the art, through: demonstrating dissemination of the kelvin from 4 K to 300 K; developing a robust framework for establishing traceability by primary thermometry; working towards the next generation primary thermometry to 700 K
