Feasibility of Substituting Ethylene with Sulfur Hexafluoride as a Tracer Gas in Hood Performance Test by ASHRAE-110-95 Method

International Journal of Occupational Hygiene, 2015
ANSI/ASHRAE 110-95 protocol is a widely acceptable method to assess the performance of laboratory hoods. In this test, sulfur hexafluoride (SF6) is applied as a tracer gas to quantitatively evaluate the performance of laboratory hoods.

放电条件下SF₆气体分解产物变化情况的研究

Gaoya dianqi, 2012
对SF6气体分解产物的组成及其体积分数进行测定和分析研究与SF6电气设备安全运行密切相关。笔者建立了SF6电气设备模拟放电试验方法,使用气相色谱法、离子色谱法及检测管法对不同模拟放电条件下SF6气体分解产物的生成过程、相对体积分数关系等方面进行研究,寻找表征不同放电故障类型的特征气体,从而得到SF6气体分解产物的变化情况与SF6电气设备故障之间的内在联系。该项研究提出对SF6气体分解产物定量检测以评判电气设备内部状态的理论与方法,对实现SF6电气设备由于放电引起的突发性故障的早期诊断和预测有着重大意义。

Sustained growth of sulfur hexafluoride emissions in China inferred from atmospheric observations

Nature Communications
Sulfur hexafluoride (SF6) is a potent greenhouse gas. Here we use long-term atmospheric observations to determine SF6 emissions from China between 2011 and 2021, which are used to evaluate the Chinese national SF6 emission inventory and to better ...
