There are three categories of tests. Class Ⅰ test is used to simulate the impact of lightning current partial import. Class Ⅰ test methods to comply SPD generally recommended for high exposure sites, For example. the lightning protection system protects the cable entrance to the building. Class Ⅱ or Ⅲ class Test Method Test SPD to withstand the impact of short duration. The SPD is usually recommended for less exposed location. All SPD should be regarded as a test "black box" as possible. Factory assessment techniques used may be included in the test, so that the Test method used was the most appropriate.
