kodak does not assign a film speed to thier B+W high speed infrared film.
they suggest trial and error (the WAG approach). the also suggest starting
points for a film speed based on which filter is being used. for the 25, 29
or 89b, they suggest starting at iso 50 for daylight exposure, iso 125 for
tungsten light. with no filter, they suggest and iso of 80. for bright or
hazy sunlight with distinct shadows, kodal recommends a starting point of
f/11 @ 1/125sec for distanct scenes, f/8 @ 1/60sec for nearby scenes.

This is all from a tech sheet off of the kodak web site (er, that would be
http://www.kodak.com  <g>). they have all of them there in .pdf form. 

Be seeing you.
