Issue 4 required the "20-second vertical flame test" for all materials inside the equipment. Issue 5 tightens the language around materials and introduces new criteria for smoke density to align with modern life-safety codes (NFPA 76). gr-63-core issue 5 pdf

GR-63-CORE Issue 5 is the premier Telcordia/Ericsson standard for NEBS physical protection, outlining mandatory spatial, environmental, and fire safety criteria for telecommunications equipment. Key updates focus on improved fire resistance for batteries, along with specific requirements for thermal, seismic, and physical testing. Purchase the standard directly from Ericsson NJDEPOT or Intertek Inform to access the full technical document.

The standard also updated requirements regarding temperature, humidity, and airborne contaminants. As data centers and edge sites become more varied (often not being traditional, climate-controlled Central Offices), Issue 5 expanded its definitions of environmental classes to help operators deploy equipment in harsher or more diverse locations with confidence. Key updates focus on improved fire resistance for

The is not just a document – it is a engineering blueprint for survival. Whether you are designing a switch, a router, a baseband unit, or an edge compute node, failure to comply means your equipment will be rejected from virtually every major telecom central office.

The document defines the minimum spatial and environmental criteria for virtually all new telecommunications equipment used in Central Offices (COs) and other environmentally controlled equipment spaces. This includes switching and transport systems, power equipment, cable distribution systems, operations support systems, and cable entrance facilities.

Map your product specifications against the specific sections of the Issue 5 PDF to determine which test cases apply to your environment class.
