Nimetus
The aim of the test is to evaluate the retention of hydrophobicity of polymeric insulating materials with the Dynamic Drop Test under accelerated and calibrated test conditions so that different polymeric insulating materials can be compared with respect to this property. The time to loss of hydrophobicity is chosen as evaluation criterion.
The test conditions are designed to accelerate the hydrophobicity reducing effects, but do not reproduce all the conditions encountered in service.
