Expanded opportunities to use existing test data for mixed flowing gas resistance, reducing the need for redundant testing on proven designs.
| Aspect | GR-63-CORE Issue 5 | GR-1089-CORE (Latest Issue) | |--------|---------------------|------------------------------| | Focus | Physical protection | Electromagnetic & electrical | | Key tests | Vibration, earthquake, fire, humidity | ESD, surge, radiated immunity, conducted emissions | | Battery scope | Spillage, thermal runaway, venting | DC power fault, grounding |
Established explicit criteria for telecommunications batteries and introduced physical assessment options that allow certain chassis designs to bypass full fire spread testing.
Perhaps the most daunting section of GR-63-Core has always been the seismic requirements (Section 4). Issue 5 refined these criteria to account for the changing density of equipment. As rack units (RUs) became packed with heavier components (like lithium-ion batteries or high-power processors), the requirements for structural integrity had to adjust. Issue 5 provides updated guidelines for mass distribution and seismic bracing, ensuring that a modern, fully loaded rack survives a seismic event just as well as the lighter legacy equipment did.
Avoid downloading "free" PDFs from unverified file-sharing sites. These documents are often outdated (Issue 3 or 4), scanned poorly, or contain malware. For compliance purposes, you must use the official, licensed version to ensure you are meeting the exact test criteria.
