ESD flooring for aerospace and avionics
Avionics build and MRO areas usually inherit their ESD requirement from contract language rather than from a building code, which changes who you are satisfying.

What is different about these rooms
01
The customer is the auditor
In aerospace the ESD program is frequently a flow down from a prime contract, so the evidence has to satisfy a customer audit, not just an internal one.
02
AS9100 sits over the top
Quality system requirements mean the floor's qualification and reverification records get treated as controlled documents, not maintenance paperwork.
03
Mixed use bays complicate the band
A bay that does both build and heavy handling needs the resistance band chosen for the most sensitive process in it, not the average one.
