ESD flooring for cleanrooms and medical device
Classified space with a resistance specification on top. Two standards that do not reference each other, both binding on the same slab.[14]
What is different about these rooms
Monolithic beats seams
A seamless resinous system with coved walls removes the particulate collection points that tile joints create, which is the usual reason resinous is specified here.
Validation documentation is heavier
Medical device and pharmaceutical facilities treat the floor's qualification records as part of a validated environment, so what gets handed over matters more.
Cleaning is written before the floor goes down
The regime that keeps the room in class can take the floor out of resistance band. Both documents need to be on the table at the same time.

Cleanroom classification by airborne particle concentration (ISO Class 1 through 9); referenced when an ESD floor also has to hold a cleanroom particulate rating.
