Annotation of standard text ASTM D1933-03(2017) :
This specification covers three types of nitrogen gas used as an electrical insulating material in electrical equipment: Type I, obtained from the air by liquefaction processes and dried; Type II, obtained from the air by liquefaction processes, deoxidized with hydrogen over a platinum catalyst, and dried; and Type III, obtained from the air by liquefaction processes and if necessary deoxidized by suitable means. Materials shall be tested and the individual grades shall conform to specified values of % volume of nitrogen and rare gases, hydrogen, and oxygen; and dew point.

1.1 This specification covers three types of nitrogen used as an electrical insulating material in electrical equipment: 1.1.1 Type I, obtained from the air by liquefaction processes and dried, 1.1.2 Type II, obtained from the air by liquefaction processes, deoxidized with hydrogen over a platinum catalyst, and dried, and 1.1.3 Type III, obtained from the air by liquefaction processes and if necessary deoxidized by suitable means. Note 1: The fact that metal containers are filled with
materials meeting this specification does not exclude the
possibility that the materials might become contaminated with
unlisted impurities.
1.2 The following safety hazards caveat pertains
only to the test method portion, Section 5, of this specification:
