This International Standard gives the accepted conditions of exposure time, temperature,
atmospheric humidity and liquid immersion for use in testing solid electrical insulating
materials. The range is sufficiently wide to enable suitable conditions to be selected so that
either of the primary objects, set out below as a) and b), of conditioning can be achieved.
These objectives aim to obtain greater reproducibility of test results by:
a) 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
b) ensuring uniformity of conditions during the testing.
This standard is not intended to be applied for determining the influence of exposure to
certain temperatures and humidity or immersions in liquids, on the properties of a material.
Procedures pertaining to the effect of an environment on a material are given in various parts
of IEC 60068.
