This Recommendation gives standard conditions of exposure time, temperature, atmospheric humidity and liquid immersion for use in testing electrical insulating materials. The range is sufficiently wide to enable suitable conditions to be selected so that either of the primary objects of conditioning can be achieved. These objects are:
a) To obtain greater reproduciblety of test results by:
i) partly counteracting the variations of the properties of the material due to the past history of the test specimens (often known as "normalizing ", here called preconditioning), and
ii) ensuring uniformity of conditions during the testing.
b) To determine the influence of exposure to certain temperatures and humidities, or immersions in during the test or both. liquids, on the properties of a material by subjecting specimens to specified conditions before or during the test or both.
