E. Bedford and published by . This book was released on 1969 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the region 13.81K to 90.188K the IPTS-68 will replace a number of previously used low temperature scales, four of which are NBS-55, NPL-61, PRMI-54, and PSU-54. It is desirable to know the relationships between these scales and the IPTS-68. At the present time these relationships can be determined, though indirectly and somewhat inaccurately, by means of an earlier intercomparison of the scales, their relationships to the CCT-64 table, and estimates of the values of the defining fixed point temperatures of the IPTS-68 on this table. Values of these relationships are presented. (Author).
