Standard Reference Materials (SRM) 1969: Rubidium Triple-Point Standard - A Temperature Reference Standard Near 39.30C

摘要

Previous work has demonstrated the practicability of using the triple point of rubidium as a temperature reference point. As a result of that work, Standard Reference Material (SRM) 1969 - the Rubidium Triple-Point Standard, has been developed. This publication reports results of an investigation of 100 SRM 1969 cells; it describes SRM 1969, the tests which were performed on the cells, the conditions under which the cells were tested, the results of the tests, and the recommended procedure for the use of SRM 1969 in calibrating thermometers. The use of SRM 1969 in clinical and biomedical laboratory applications should significantly enhance the accuracy of temperature measurements in the region of body temperature.
