The calibration of the salt spray corrosion test chamber is carried out according to the salt spray calibration method stipulated in the standard of GB/T5170.
8-2008 "Electrical and Electronic Products Environmental Test Equipment Inspection Method Salt Spray Test Equipment": the fixed exchange rate of the glass funnel receiving area of 80cm2 is fixed on the measuring cylinder or connected to the measuring cylinder (50mL, resolution is 1mL) through the hose, placed in the specified position, and after the experiment is completed (continuous spray for 16 hours), the volume of salt spray settlement in each measuring cylinder is read.
Then divide by the calibration time to get the salt
spray settling rate at each measurement point.
As the core index of the salt spray corrosion test chamber, the reasons affecting the inaccurate salt spray settlement rate of the salt spray are analyzed as follows: 1.
The accuracy of the measuring cylinder; 2.
Error caused by the line of sight not being vertical during reading; 3.
The error caused by the amount of salt spray remaining on the wall of the funnel and the measuring cylinder; 4.
The error
caused by the water droplets falling on each measuring cylinder when opening the salt spray corrosion test chamber.
Note: The salt spray amount settlement rate explained by the noun The amount
of salt spray collected every 80cm2 per hour.
