Type of article: Periodical article

Summary

REVIEW OF THE CONCEPT OF AN INTERNATIONALLY-AGREED TEMPERATURE SCALE AND THE PRACTICAL CONSIDERATIONS WHICH INFLUENCE ITS CONSTRUCTION AND UTILIZATION. THIS SETS THE SCENE FOR A DESCRIPTION OF THE CURRENT INTERNATIONAL PRACTICAL TEMPERATURE SCALE (IPTS-68) AND ITS PRESENTLY-PERCEIVED DEFICIENCIES, ALSO OF NEW PRIMARY THERMOMETRY DATA AND TECHNICAL DEVELOPMENTS WHICH WILL VERY PROBABLY FORM THE BASIS FOR CONSTRUCTING A REVISED SCALE IN THE NEAR FUTURE. SUCH A REVISION IS TO INCLUDE A SUBSTANTIAL DOWNWARDS EXTENSION OF THE TEMPERATURE RANGE COVERED BY THE SCALE, PROBABLY TO 0.5 K AND PERHAPS INTO THE MILLIKELVIN REGION. BRIEF CONCLUDING REMARKS COVER THE RELATIONSHIP BETWEEN STATE-OF-THE-ART METROLOGY AND THE THERMOMETRIC REQUIREMENTS OF SCIENCE AND INDUSTRY.
