Solid electrical insulating materials - Standard conditions for use prior to and during the testing
 N JIS C 2142

Annotation

This Standard 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 reproducibility of test results by:

1) partly counteracting the variations of the properties of the material due to the past history of the test specimens, and

2) ensuring uniformity of conditions during the testing.

b) To determine the influence of exposure to certain temperatures and humidities, or immersions in liquids, on the properties of a material by subjecting specimens to specified conditions before or during the test or both.

NOTE : The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 60212 : 1971 Standard conditions for use prior to and during the testing of solid electrical insulating materials (MOD)

The symbols which denote the degree of correspondence in the contents between JIS and the corresponding International Standard are IDT (identical), MOD (modified) and NEQ (not equivalent) according to ISO/ IEC Guide 21.
