This standard describes the samples containing a sulfur dioxide atmosphere environment The condensed water-the conventional conditions of the experiment in the climate of the climate, the German industrial standard DIN EN ISO 6988: The March 1997 version did not include the contents of the concentration of the sulfur dioxide, which contained it The test results obtained in the test are compared. Because the transformation of the samples under different systems cannot be removed, it is very effective to put the same corrosion -resistant system in the same test device for testing.
What needs to be considered during the test process of different corrosive systems and different materials at the same time is that they are affected by sulfur dioxide different effects.
The duration of the test:
The duration of the experiment is 1, 2, 5, 10, 15, or 20 cycle cycles. When the test sample appears or does not allow an impact on the appearance or function, it can stop the test after reaching a certain degree of corrosion.In most cases, the water and sulfur in the test cabin must be replaced after multiple test cycle cycles.
The corrosion product shall be removed from the sample when the temperature is from 18 ° C to 28 ° C. Here you can use hydrochloric acid. Each liter contains 3.5g
ring six thread tetramine , P 1.10g/ml, such as 500ml concentrate HCL, P 1.19g /ml, chemically pure, and blend 1 liter with completely salted water.
Further dissolution can be performed in accordance with international standard ISO 8407.当样件去除腐蚀产物后应当放入水中好好冲洗，然后烘干，紧接着在温度为18℃至28℃这个范围内放在干燥器中进行秤Heavy.

12.15 degrees sample rack, 60 degrees sample rack
used to simulate the simulation of high humidity areas under the acceleration environmentOr damage to metal, paint and organic materials, the use of condensed water test boxes will get results faster than in the natural environment.The evaporation and condensation process on the test sample is actually a distillation process that removes all impurities.So use tap water as a medium. It is important to note that the condensed water test box is different from the general humidity test box. Concrete water test exposes the product in an environment with a relative humidity of more than 95%for condensation.The high -humidity steps during salt fog testing are the same principle.
