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.
under 1.0 x 10^9ohmsANSI/ESD STM97.1
under 100voltsANSI/ESD STM97.2
2.5 x 10^4 to 1.0 x 10^6ohmsANSI/ESD STM7.1 / ASTM D257 (as cited on manufacturer TDS)
What is different about these rooms
01
The band runs 10^6 to 10^9 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.
