3.2 Evaluation of the test pass/fail criteria observation sample 1 observation sample 2

number of over-current trip-outs 0 0 tracking no no erosion depth more than 3 mm no, (< 1 mm) no, (< 1 mm) erosion reached the core no no sheds are punctured no no housing is punctured no no interface is punctured no no

Requirements The test is regarded as passed if, on both test specimens:

- no tracking occurs - for composite insulators: erosion depth is less than 3 mm and does not reach the core, if applicable - no shed, housing or interface is punctured.

Result The test was passed.
