Test Conditions:
The cycle of stresses applied to the insulators and repeated for a
period of 5 000 h is shown in Figure 3. The cycle is designed
so that the test specimens are also subjected to the effects of temperature variation and condensation .

Artificial Rain:
The artificial rain shall be provided by nozzles mounted above the test specimens and outside their perimeter (see Figure 4 ). The
average precipitation rate shall be in accordance with IEC 60060-1 . Water of a minimum resistivity of 85 nm shall be used. Each
of the test specimens is sprayed individually.

Salt fog calibration:
The calibration will be carried out before the start of the test.
At least two clean collecting receptacles with a collecting area of 8 000 mm2 ± 2 000 mm2 and a maximum height of 100 mm each are placed as close as practical to the position of the ends of the test object. The receptacles are positioned in such a way that they are not shielded by the test specimens and to avoid dripping from the construction elements of the chamber or another source.
They should collect between 1,5 ml and 2,0 ml of precipitation per hour (corrected to 8000 mm2 collecting area) averaged over a minimum period of 16 h.
NOTE The flow rate necessary to obtain such precipita tion (typically of the order of 0,3 l/m3h based on a chamber not larger than(15 m3) should be noted. (The water flow rate is defined in l itres per hou r and per cubic meler of the test chambe r volume. )
Subsequently du ri ng the test, the flow rate should be checked at least every 100 h and should remain within ± 25 % of the initial value.
it is not permitted to re-circulate the water.
