## Where the underfloor space is used as a supply air plenum for underfloor air distribution, the airflow performance and air-sealing requirements of this standard apply in addition to the structural requirements.
−## Where the understructure is used as a signal reference grid or as an equipment grounding path, the grounding and bonding requirements of [[syncs/grounding-and-bonding]] apply in addition to this standard.

# Grounding and Bonding {toc}
−## A conductive understructure can serve as a signal reference grid and as part of the equipment grounding path; where it does, it shall be bonded in accordance with the National Electrical Code and [[syncs/grounding-and-bonding]]. {note}
+## A conductive understructure can serve as a signal reference grid and as part of the equipment grounding path; where it does, it shall be bonded in accordance with the National Electrical Code and [[sync/grounding-and-bonding]]. {note}
## Where the floor is used as a signal reference grid or equipment grounding path, all non-current-carrying metal parts of the understructure, including pedestals and stringers, shall be bonded to the equipment grounding conductor in accordance with NEC Article 250 and Article 645.
