SF6 dielectric strength 2

[smallfish]

I am searching for information in relation to the dielectric strength of SF6 in kV/mm. Please suggest publications that have the answer or tell me the answer. Thank you.

for:
1.1.2. Dielectric Strength. Its dielectric strength is 2 to 3 times that of standard air and has high thermal stability. The dielectric increases with increasing pressure and at 3 atmospheres, the dielectric strength is roughly equivalent to insulating oil. These properties make it useful in gas-insulated buses and compartments which contain electrical switchgear components.

for the SF6 dependence kV versus pressure at 12mm gap. Then, divide kV by 12mm to obtain the SF6 dielectric strength in kV/mm.
The original posting does not address a pressure at which the kV/mm for SF6 is sought.
