Certain chassis designs proven to be fire-resistant can now claim conformance through a physical assessment without requiring destructive fire spread testing.

: Dictates specific directional cooling paths, favoring front-to-rear or front-bottom to top-rear (EC-Class F1-R3) air distribution systems. 3. Seismic Integrity and Vibration Resistance gr63core issue 5 pdf link

GR-63-CORE is one half of the foundational NEBS (Network Equipment-Building System) documents—the other being GR-1089-CORE (electromagnetic compatibility and safety). While GR-1089 deals with electrical interference and lightning, : thermal stress, seismic activity, fire resistance, airborne contaminants, and handling/storage conditions. Certain chassis designs proven to be fire-resistant can
