Topics Of Discussion DOP Efficiency Tester Q-107 Dual Laser Leak/scan Testing Particle Counters High Efficiency Air Filters Fire Resistance Summary
DOP Efficiency Tester (Q-107) Developed 1940s Guaranteed Performance Efficiency Pressure Drop Upstream Aerosol Hot DOP (Dioctlyphthalate) A Non Destructive Test
Q-107 Penetrometer
Dual Laser Efficiency Developed Late 1970’s Non Destructive Test Counts Size & Individual Particles Filter Pressure Drop
Dual Laser Efficiency This machine has the ability to see particles that are .1 and larger (12) separate bins (Particle Sizes) that can be looked at. This machine will use PSl’s clean challenge.
Leak/Scan Testing Non Destructive Test Locate Gross Leaks Photometer or Particle Counter Manual Autoscan Cleanroom Applications
Autoscan A Non-destructive Test to Locate Leaks Particle Counter Method Removes Operator Variability
Particle Counters Monitor Dust/Particles Determines Particle Size Scan Test Incandescent Light .3 Micron Laser Light .07 Microns
