The grunge design trend: Why raw, messy aesthetics are back (and how to use them in 2026)
Discover why grunge design is trending again in 2026 and how to use textures, distressed type, and controlled chaos without sacrificing clarity or hierarchy.
GR-63-CORE Issue 5 defines the latest NEBS technical standards for physical telecommunications equipment, focusing on durability against earthquakes, fire, and extreme thermal conditions to support modern 5G and data center infrastructure. The standards are updated to handle higher-density equipment, improved airflow management, and smaller, edge-computing, street-side cabinet deployments. For the full, licensed documentation, visit the Ericsson Standards Store.
Operating Conditions: Equipment must remain functional between -5°C and 50°C, with specific humidity and altitude testing required for fully loaded racks.
The GR-63-CORE standard covers several critical physical performance categories: SEISMIC Tests Certificate - Lande
Streamlined Fire Testing: Certain chassis designs with proven resistance to fire spread can now claim conformance through physical assessment alone, potentially eliminating the need for full fire spread testing.

C. Battery Safety (Critical Update in Issue 5)
Issue 5 introduced specific handling for Lithium-ion (Li-ion) batteries, which were not prevalent during Issue 4.
Step 2: Pre-Test with Simulation
- For seismic, use finite element analysis (FEA) with the provided test response spectrum (TRS).
- For thermal, run CFD models using Issue 5’s new transient profiles.
Compared to previous versions, Issue 5 introduced specific updates to streamline testing: Fire Resistance:
