Summary

DESCO INDUSTRIES INCORPORATED's STATFREE® ESD ULTRA CLEAR BAG meets ANSI/ESD S20.20 qualification requirements. Test results confirm interior and exterior surface resistance falls within the specified range of ≥1.0x10^4 to <1.0x10^11 ohms at both 12% and 50% relative humidity (23°C), after 48-72 hours conditioning. Surface resistance measurements (100V) for 10 specimens at 12% RH show interior min 1.02x10^9 ohms, max 1.03x10^10 ohms; exterior min 1.90x10^9 ohms, max 6.76x10^10 ohms. At 50% RH, interior min 4.83x10^9 ohms, max 9.22x10^9 ohms; exterior min 6.55x10^9 ohms, max 8.96x10^9 ohms. Discharge shielding testing was not applicable per ANSI/ESD STM11.31. Tests were conducted using ETS Controlled Environment Chamber (Model 5532), SCS Surface Resistance Meter (Model 770761), SCS Concentric Ring Probe (Model 770007) for STM11.11, and ETS Shielded Bag Test System (Model 4431T) for STM11.31. Calibration records are maintained at Desco's corporate lab in Sanford, NC.
