ESD flooring for aviation and faa facilities

Towers and communications rooms sit under FAA-STD-019, which sets a floor resistance range deliberately above a typical manufacturing ESD floor.[11]

ANSI/ESD S20.20 measures the person, their footwear and the floor as one circuit PERSONSHOES THE FLOOR, AND ITS PATH TO GROUND One circuit, measured end to end. Under 1.0 x 10⁹ ohms (STM97.1) Under 100 volts walking (STM97.2) Change the footwear and the reading changes, which is why the floor is never qualified alone.
S20.20 qualifies a system, not a surface. The person and their footwear are inside the measurement.

What is different about these rooms

01

The band runs 106 to 109 ohms

Higher than a manufacturing floor, and on purpose. The reason is personnel safety around energized equipment rather than component protection.

02

Flooring is one clause in a grounding document

FAA-STD-019 is primarily about lightning and surge protection, grounding, bonding and shielding. The floor sits inside that wider picture.

03

Verify the revision with contracting

Revision F with Change 3 is confirmed. A Revision G is referenced in recent procurement filings but could not be confirmed on faa.gov, so check it.
