JJF 2058-2023 "Specification for constant temperature and humidity laboratory environment parameter calibrating" applies to the environment parameter calibrating of laboratories with constant temperature and humidity at temperature (15~ 30) ° C and relative humidity (30~ 80) %. This specification refers to several relevant standards, including environmental test equipment temperature, Humidity parameter calibrating specification JJF 1101-2019, lighting Measuring method GB/T 5700-2008, air cleanliness grade standard GB/T 25915.1-2010, etc. The terminology section defines key terms such as constant temperature and humidity laboratory, workspace, steady state and temperature deviation. Constant temperature and humidity laboratories provide stable environmental conditions such as temperature Humidity for various experiments and tests that require precise control of environmental conditions. This specification ensures that the laboratory can accurately maintain the specified temperature Humidity range and calibrate Miscellaneous environment parameters such as illumination, wind speed, noise and static pressure difference to ensure Reliability and reproducibility of experimental results.
