I don't think that IEC TC74, the godparents of IEC 60950 are concerned with
what the NEBS do or say.  They didn't even really want to be in the Telecom
business.

More complicating, an IEC product committee (TC74) is bound to abide by all
manner of horizontal IEC standards and cannot change things on its own.
The "horizontal" standards are demonstrably wrong, witnees the lack of
bodies killed by telecom energies, but nobody has the time, money or energy
to go and become a member of these horizontal committees and fight the good
battle there. 

The voltages and currents used in Telecommunications, "officially" are
hazardous under any number of IEC Standards, but not treated so in IEC
60950.  By IEC standards, telecom wiring probably ought to be run in
conduit by licensed electricians.  We've done well in IEC, let's not push
it by dragging in proprietary specifications such as the NEBS.
