JJF 1030-2023 "Specification for the technical performance test of Thermostatic bath for temperature calibrating" applies to the testing of Temperature uniformity, temperature fluctuation, and temperature rise (fall) rate of liquid Thermostatic bath at Temperature range -80 ° C to 300 ° C. This specification refers to a number of standards, including industrial platinum, copper thermistors, pressure thermometers, etc. The terminology section defines relevant terms for the Thermostatic bath work area, such as Thermostatic bath Temperature uniformity and temperature fluctuation, and the use of fixed and mobile thermometers. Thermostatic bath is required to be in a steady state to maintain the Stability and Accuracy of the temperature in the working area, ensuring its Reliability and Accuracy during calibrating and verification.
