The nuers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here.

US5779763A - Process for recovering semiconductor …

A process for separating perfluoro compound gas or vapor from another gas, typically nitrogen, in a gas mixture. The process involves a coination of merane separation and condensation, and is particularly useful in the semiconductor industry, for treating exhaust gases from cleaning of chemical vapor deposition chaers. Operation of the condensation step at temperatures no lower than

As an oil alternative, SF6 gas introduces new and growing concerns about its effects on the atmosphere. SF6 has an extremely long atmospheric lifetime, estimated between 800 to 10,000 years, and has a global warming potential 24,900 times that of carbon dioxide. As a result, SF6 is among the most potent of greenhouse gases.

The dielectric strength of SF6 gas reduces significantly at lower pressures, normally as a result of lower aient temperatures. Monitoring of the density of the SF6 gas is critical and some designs will block operation of the circuit breaker in the event of low gas density. Circuit breakers are available as live-tank or dead-tank designs.
