1.1 This standard specifies the atmospheric conditions for testing of materials, products, equipment, etc, and applies to such tests where atmospheric conditions need to be controlled to obtain comparable and reproducible results or to conduct measurements where test results obtained under different conditions have to be reduced to standard conditions.
1.2 This standard does not apply to the basic standards of weights and measures, to the precision measurement made in terms of these basic standards and to such tests as calibration of test gauges, precision tools, etc, and to the cases covered in 0.9.
1.3 This standard is not applicable to cases where testing is done under the atmospheric conditions existing at the time and place where measure-ments are made (for example electric motors, generators, transformers, etc) and where no question of controlled atmosphere arises.
