introduction
This specification is based on JJF 1071-2010 "Rules for Compiling National Measurement and Calibration Specifications", JJF 1001-2011
Use Measurement Terms and Definitions "and JJF 1059.1-2012" Measurement Uncertainty Evaluation and Expression "as the basic series of regulations
Fan to write.
This specification adopts GB/T 5170.1-2016 "General Rules for Inspection Methods of Environmental Test Equipment for Electrical and Electronic Products"
Definition of relevant terms and technical content.
This specification is a revision of JJF 1101-2003 "Code for Calibration of Temperature and Humidity of Environmental Test Equipment", and
Compared with JJF 1101-2003, in addition to editorial changes, the main technical changes in this specification are as follows.
--- The name of the specification was changed to "Environmental Test Equipment Temperature and Humidity Parameter Calibration Specification", the specification guidance and reference
The goals are clearer and more specific;
--- Environmental testing equipment, working space, steady state, temperature fluctuation, humidity fluctuation,
Temperature uniformity, humidity uniformity, etc., modified the calculation method of temperature and humidity deviation and temperature and humidity fluctuation,
Consistent with the relevant content of GB/T 5170.1-2016;
--- Revised the relevant content of the technical requirements of environmental testing equipment, and changed the requirements of the equipment to temperature and humidity
Parameter requirements;
--- Standards generally use multi-channel temperature (temperature and humidity) display instruments or multi-channel temperature (temperature and humidity) measurement
Device;
--- Increasing the suggestion of measuring point layout information of environmental test equipment with volume less than 0.05m3;
--- It is recommended to change the recalibration time interval to 1 year;
--- Deleted the "Dry and Wet Bulb Method for Measuring Relative Humidity" appendix;
--- Revised the uncertainty analysis of temperature and humidity deviation calibration results.
The previous releases of this specification are.
--- JJF 1101-2003 "Code for Calibration of Temperature and Humidity of Environmental Test Equipment".
Specification for temperature and humidity parameter calibration of environmental test equipment
1 Scope
This specification is applicable to drying ovens with temperature range -80 ℃ ~ 300 ℃ and humidity range 10% RH ~ 100% RH
Incubator, climate aging box, mold test box, salt spray test box, corrosive gas test box, high and low temperature test box, delivery
Calibration of temperature and humidity parameters of environmental test equipment such as humid heat test chamber, constant temperature and humidity chamber.
The temperature and humidity parameters of environmental test equipment in other ranges can also be calibrated with reference to this specification.

3 Terminology
The terms and definitions defined in JJF 1001-2011, GB/T 5170.1-2016 and the following apply to this specification.
3.1 Environmental testing equipment environmental testing equipment
Equipment that simulates one or more environmental conditions and performs environmental tests on products.
3.2 working space
The part of the environmental test equipment that can maintain the specified temperature and relative humidity performance within the specified deviation range
space.
3.3 steady state
The variation of temperature and relative humidity at any point in the working space of the environmental test equipment reaches the performance index of the equipment itself
Time-seeking state.
3.4 Temperature deviation
When the environmental test equipment is in a stable state, the highest temperature and the lowest temperature of each measurement point in the working space are measured within the specified time
The upper and lower deviations between the temperature and the set temperature. Temperature deviation includes temperature deviation and temperature deviation.
[GB/T 5170.1-2016, definition 3.2.4]
3.5 Relative humidity deviation relativehumiditydeviation
When the environmental test equipment is in a stable state, each measuring point of the working space actually measures the highest relative humidity and the
The upper and lower deviations between the low relative humidity and the set relative humidity. Relative humidity deviation includes relative humidity deviation and relative humidity
Lower deviation.
