No, it isn't. It was used for a project at NIST, and is the basis of
the EMC CNC program.
It is based on Allen-Bradley's variant of RS274-D. There is an IEEE
document that
defines RS274-D. It is copyrighted. I wonder if there is an equivalent
ISO standards
document (it seems there must be).

The bigger machines have Fanuc, Heidenhain, Fadal, etc. variants.
