As it is indicated it was prepared as work sponsored by the US goverment.
It now has an unclassified status (unlike the later development NEC4).
As a result the works seems to have a public domain status (see 17 USC105);
despite it not explicitly being stated in the code or indeed any of the
associated reports.
There exits several other commercial products which are widely used
which include support for either NEC2 or NEC4; in the former case
no additional licence is necessary, in the second a licence must
be obtained in return for a fee payed.
