1.1 本规范适用于用作电绝缘气体的六氟化硫。 注1: 本规范仅适用于购买的天然气。然而，本标准中提及的试验方法可能有助于评估在用或已用气体。试验方法 D2284 可能特别有用，因为许多六氟化硫分解产物是酸性的。试验方法 D2284 不得用于评估六氟化硫分解总量，也不得用于识别污染物种类。这只能通过气相色谱法和类似的仪器技术来实现。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This specification applies to sulfur hexafluoride for use as an electrical insulating gas. Note 1: This specification is intended to apply only to gas as purchased. However, the test methods referred to in this standard may be useful in the evaluation of in-service or used gas. Test Method D2284 may be particularly helpful since many sulfur hexafluoride decomposition products are acidic. Test Method D2284 should not be used to evaluate the total amount of sulfur hexafluoride decomposition nor to identify contaminant species. This can only be done by gas chromatography and similar instrumental techniques. 1.2 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.
