Issue 5 introduced a for qualifying chassis designs that are already proven to resist fire spread. Instead of performing a full fire‑spread test, manufacturers can now claim conformance based on a physical assessment .
is the most widely recognized standard for telecommunications hardware deployment in North America. Originally developed by Bell Labs, it ensures that network infrastructure equipment can survive harsh environmental stresses while preventing hazards that could threaten system uptime or personnel safety.
