Abstract
This specification applies to Type I gaseous air, both atmospheric and that synthesized by blending oxygen and nitrogen in proper proportions, used as an electrical insulating material in electrical equipment. Appropriately sampled specimens shall undergo tests and should adhere accordingly to chemical requirements as to dew point, and specified compositions for oxygen, carbon monoxide, carbon dioxide, and nitrogen.
