SG403A Containment Test Results Average SF 6 release concentration per 5 min test runs Containment protection factor/run (interior SF 6 concentration 10,000 ppm/average SF 6release release concentration) Number of peak releases SF 6/run /run due to periodic loss of containment (peak release defined as SF 6 release of > 0.10 ppm which results in loss of > one log protection factor) Average SF 6 peak release concentration/run Peak release containment protection factor/run (interior SF 6 concentration 10,000 ppm/average SF 6 peak release concentration)
