Requirements of environmental testing methods of analytical instruments for constant temperature and humidity test chamber

GB / T 11606.6-89 "Analytical Instruments Environmental Test Method Constant Humidity Test" standard specifies the analysis instrument constant humidity test grouping, test conditions, test duration and test method. This standard is applicable to assess the suitability of the instrument to work under high relative humidity environment conditions.

Requirements of the environmental testing method of analytical instruments for constant temperature and humidity test chamber:

1. The working space of the test chamber should be equipped with sensors to monitor the temperature and humidity of the test chamber.

2. The temperature and relative humidity in the effective working space of the test box should be able to be kept within the range required by the constant humidity test group in the standard.

3. The condensate in the constant temperature and humidity test chamber must be continuously drained out, and it cannot be used again before purification treatment.

4. The resistivity of the water directly used to generate humidity is not less than 500Ω? M.

5. When the analysis instruments have requirements on the influence of wind speed, vibration, etc., they should be stated in the product standard.

6. There should be well-insulated terminals and devices to ensure cable access in the test box in order to check the electrical performance of the analytical instruments in the test box.

7. The condensed water on the inner wall and the top of the test box cannot drip on the analytical instrument.

8. The test chamber should be equipped with observation windows and lighting devices.
