Salt spray test chamber for SAE J1563 cyclic salt spray test
 
In cyclic corrosion testing, test specimens are exposed to at least three different types of environmental conditions: a. Corrosive Solution, wet conditions, dry conditions and cycled from one environmental to another.
 
Lenpure Salt Spray Test Chamber could evaluate the anti-corrosion ability of materal and material coating , make a comparsion about the product techniques and quality of similar coating and products , It be used to test the electronic elements, and metal materials and industrial products.

 
The diagram in figure 1 is an example of cyclic test which consists of three environment type:


 
 
Prior to testing, the type of specimen surface and the surface and the panel preparation should be agreed to by personnel involved, and should simulate actual production material and conditions. The number of test specimens selected should be sufficient to ensure that the test result are statistically significant at some predetermined confidence level. Any unusual observations made during panel preparation should be recorded and reported as part of the test results.
 
In addition to the test specimens, control panels should be tested concurrently. It is preferred that control panels be provided which bracket the expected test panel performance. The controls will allow the normalization of the test conditions during repeated running of the test and will also allow comparison of test results from different repeats of the test.
 
In situations where the test cycle has to be interrupted due to equipment malfunction goliday breaks, the test panels should be stored under the least corrosive conditions available. For example a dry cycle or a freeze cycle. Preferably, test interruptions should not exceed 5 days but all interruptions and handing of panels should be reported.
 
Transition between conditions is considered ramp time. Ramp time from condition to condition can be a critical factor affecting results. Depending on types of equipment used and cabinet loading, ramp time may vary and should be monitored and rec
