JJG 2020-1989 273.15～903.89 K Temperature Measuring Instruments
Abstract
The temperature scale is a unified method of expressing temperature values. The temperature scale currently implemented in China is the International Practical Temperature Scale of 1968 (revised in 1975), hereinafter referred to as IPTS-68. The temperature measurement instrument verification system for temperatures ranging from 273.15 to 903.89 K was established based on IPTS-68. It is an important basis for transferring temperature values from national reference instruments to working measurement instruments through fixed-point methods and comparison methods at various levels of measurement standards.
