Standard Test Method for Air and Carbon Tetrafluoride in Sulfur Hexafluoride by Gas Chromatography
N D2685
Annotation
This test method covers the determination of air (Note 1) and carbon tetrafluoride as impurities in sulfur hexafluoride.
NOTE 1—Nitrogen, oxygen, or any of their mixtures is considered to be air. Commercial grade air or nitrogen is used for standardization.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Метод стандартной пробы для воздуха и четырехфтористого соединения углерода в гексафториде серы газовой хроматографией
Этот метод тестирования покрывает определение воздуха (Примечание 1) и углерода tetrafluoride как примеси в гексафториде серы.
ПРИМЕЧАНИЕ 1 — Азот, кислород или любая из их смесей считаются воздухом. Воздух товарного сорта или азот используются для стандартизации.
