SF6-filled tools for testing

Myth About SF6 Gas In Electrical Equipment. May 25, 2020Buildings containing SF6-filled indoor equipment should be provided with ventilation; natural ventilation would normally be adequate to prevent the accumulation of SF6 released due to leakage (see IEC 61634, sub-clause 3.4: "Safety of personnel" and IEC 61936-1).

  • SF6 Lasercheck P3:vac - ISM Deutschland GmbH

    For integral leak testing, the SF6 filled test piece is placed in a test chamber. The test chamber is then evacuated to an absolute pressure of about 10 – 20 mbar. SF6 escaping from the specimen and thus entering the test chamber is drawn into the system’s detection chamber via the vacuum module.
