In the Section 7 of the latest IEEE 383-2015 , it is required that the qualification of the cables located in the mild environment shall include long-term water immersion testing for 1 year period. Also, in some third generation nuclear power plant, it is required that the 1E or non-1E shall be conducted the test for spray/immersion conditions with extreme pH in non-DBA Conditions. Based on this, the test for spray/immersion conditions with extreme pH is more and more paid attention. However, the research on this test has not been done in China. The aim at this article is doing the research of test of spray/immersion conditions with extreme pH, and is to discuss and introduce the qualification method.
