Withdrawn
A Withdrawn Standard is one, which is removed from sale, and its unique number can no longer be used. The Standard can be withdrawn and not replaced, or it can be withdrawn and replaced by a Standard with a different number.

For Harmonized Standards, check the EU site to confirm that the Standard is cited in the Official Journal.
Only cited Standards give presumption of conformance to New Approach Directives/Regulations.

Describes two methods for evaluating and comparing the resistance of solid dielectric materials to the initiation of tree-like patterns, i.e. a network of tubular channels wherein partial discharges may occur, during short-time stressing, with a highly divergent electric field. The tests are primarily used at power frequencies (48 Hz - 62 Hz). The tests are generally carried out at room temperature. If other temperatures are desired, these should not exceed the range of normal use of the material to be tested.
