ECMA 46 tape standard

I've been asked about a quarter-inch tape standard from 1976, called
ECMA-46. It's apparently 63 bits per mm, phase encoded. I work that
out to 1600 bits per inch. Now, is this one of the early QIC (Quarter-
Inch Committee) standards? Could it be QIC-11, the four-track system
used on Sun-2 machines? Or is it something else entirely? And how
could such a tape be read, nowadays?
