Needs

The emerging institutes in this project (JV, RISE, DFM, CMI, SMU and UL) are all intermediate level NMIs in Europe, but they currently lack a realisation of high temperature primary standards. After the recent redefinition of the kelvin one of the most promising primary reference standards for high temperature is to interpolate between high temperature fixed points whose transition temperature have been established with high accuracy, using a radiation thermometer as the interpolation device. However, the method has not yet been tried on a large scale outside the major NMIs. An important pillar of the metrological community is the ability to compare results across different institutions and countries, but this requires that a certain number of institutes are capable of realising the quantity to be compared. This project aims to endow the emerging NMIs with primary thermometry capabilities, and hence help the European metrology community to improve its robustness, but at the same time avoid a fragmented and uncoordinated capacity building. The consortium will create nascent regional centres of excellence in the field, by coordinating the activity in the Scandinavian and central European regions, respectively.
However, the project also responds to emerging industrial needs. The participant NMIs represent countries with substantial production, processing and manufacturing industry with expressed needs for better high temperature standards. Examples include the metallurgical industry, manufacturing of building materials and H2 production.

Objectives

The overall objective of this project is to endow six European NMIs (JV, RISE, DFM, SMU, CMI and UL) with the competence and resources to realise a primary high temperature scale at the highest level, in accordance with the revised MeP-K. DFM will work closely with the external partner DTU. The project will also demonstrate the new capabilities in three different ways: by conducting an interlaboratory comparison, by publishing two peer reviewed papers demonstrating progress in the field, and by demonstrating examples of dissemination to industrial stakeholders.
The specific objectives of the project are:

1. To transfer knowledge to the emerging NMIs on the realisation of the ITS-90 by extrapolation from a single fixed point. An important part of this is the characterisation of the radiometer used to extrapolate temperature, such as its size-of-source sensitivity, linearity and spectral response. This is addressed in WP 1.
2. To construct a set of medium- to high-temperature fixed points for radiation thermometry adapted to the technical means of emerging NMIs. This includes assessment of the quality of the cells and experimental determination of the optimal thermal conditions for their use. WP 1 and WP 2 address this objective.
3. To realise the MeP-K through the application of the multi fixed point scheme using a variety of radiation thermometers and temperature ranges in accordance with the needs of emerging NMIs, and to compare at least one realisation to the ITS-90. The target uncertainty of the realisations is 0.6 K at 1800 K and 1 K at 2300 K. This is addressed in WP 3.
4. To perform an interlaboratory comparison linked to key comparison CCT-K10 to underpin improved calibration and measurement capabilities (CMCs) for participant laboratories in the field of radiation thermometry. This is addressed in WP 4.
5. To facilitate the take up and long term operation of the capabilities, technology and measurement infrastructure developed in the project by the measurement supply chain (NMIs/DIs, calibration and testing laboratories), standards developing organisations (e.g. CIPM CCT, EURAMET TC-T), and end users (e.g. metal forming, building insulation, and steam reforming). This is addressed in the impact work package, WP 5.
