Demands prolonged low-humidity soaking steps, notably tracking performance limits down to 5°C with relative humidity below 15%.
A significant portion of GR-63-CORE is dedicated to seismic performance. It specifies test methods for withstanding office vibration, transportation vibration, and earthquakes. The seismic criteria are tied to geographical zones in the United States (Zone 0 to Zone 4), with Zone 4 representing the highest risk. The standard provides required response spectra and representative time-domain data for testing.
