Are you building or vetting an off-the-shelf vendor ?
The standard defines the 19-inch rack as the default standard for most IT applications.
Major manufacturers like Schneider Electric and IBM design their enterprise equipment to be strictly compliant with this standard to avoid installation delays and "orphaned" equipment that cannot be secured. Although the standard bodies do not provide individual compliance certificates for every product, hardware marketed as "EIA-310-E compliant" is built to these specific tolerances.
