At present, in the field of measurement, there are more unified conventional requirements for the requirements of constant temperature and humidity laboratories, such as temperature and humidity deviation, uniformity, stability and fluctuation requirements, but the calibration methods are not uniform; for some high-precision experiments There are also some special requirements in the laboratory, such as the air flow rate, fresh air volume, ventilation frequency, indoor light illuminance, environmental cleanliness, illuminance, noise, etc.
, and there is no technical basis to refer to.
Therefore, in order to unify and standardize constant temperature The environmental parameter evaluation method of the wet laboratory correctly guides the use and maintenance of the constant temperature and humidity laboratory.
It is necessary to formulate a unified national constant temperature and humidity laboratory measurement performance calibration specification.

It is necessary to formulate a unified national constant temperature and humidity laboratory measurement performance calibration specification.
The "Specification for Calibration of Environmental Parameters in Constant Temperature and Humidity Laboratory" is based on JJF 1071-2010 "Rules for the Compilation of National Metrology and Calibration Specifications", JJF 1001-2011 "General Metrology Terms and Definitions" and JJF 1059.
1-2012 "Measuring Uncertainty Evaluation and Expression 》Compiled for the basic series of specifications, applicable to the calibration of environmental parameters in constant temperature and humidity laboratories (hereinafter referred to as laboratories), not applicable to the calibration of biosafety laboratories and medical laboratories.
It is formulated for *.

It is formulated for *.
Refer to the following standards: GB 50073-2013 "Code for Design of Clean Workshops", GB 51110-2015 "Code for Construction and Quality Acceptance of Clean Workshops", GB 50243-2016 "Code for Construction Quality Acceptance of Ventilation and Air-Conditioning Engineering", GB/T 5700- 2008 "Lighting Test Method", T/CECS 644-2019 "Constant and Humidity Laboratory Engineering Technical Regulations" and JJF 1101-2019 "Environmental Testing Equipment Temperature and Humidity Parameter Calibration Specification".
In addition, the constant temperature and humidity laboratory is a workplace that simulates a variety of environmental parameters, and can provide constant temperature and constant humidity, and the various parameters provided meet the requirements of the experimental conditions.
According to the different types of simulated environmental factors, the laboratory can be divided into a constant temperature laboratory, a constant temperature and humidity laboratory; according to the level of the laboratory, it can be divided into an ordinary laboratory and a high-precision laboratory.
The laboratory air conditioning system is mainly composed of air conditioning cold and heat source units, terminal air handling units, air conditioning delivery, return air systems, fresh air systems and other parts.
The main function of the laboratory is to provide the required experimental conditions and meet the requirements of testing, scientific research or various types of experiments.
It is the basic condition and guarantee for conducting experiments.
