Telcordia GR-63-CORE Issue 5, published in December 2017, is available for purchase through authorized distributors, including the official Ericsson/Telcordia site. This NEBS standard update introduces refined requirements for fire resistance, chassis assessment, and environmental testing.

Reduced Testing for Proven Designs: Certain chassis designs proven resistant to fire spread can now claim conformance through physical assessment alone, bypassing formal fire spread testing.
Technical Summaries: Detailed explanations of vibration and earthquake test methods can be found through specialist engineering sites like Vibration Research. GR-63 - NEBS Requirements: Physical Protection - Telcordia gr63core issue 5 pdf link
Hygroscopic Dust: Testing for resistance to hygroscopic dust is eliminated for products operating at voltages highly immune to leakage current effects.
But without specific information on issue 5, I'll have to make educated guesses. If "gr63core" is about core sampling in geology, perhaps the paper could discuss issues like contamination in core samples, sampling techniques, or data interpretation challenges.
