Sorry - I wasn't paying attention. This is the one I meant to grab:

Same page (which includes another study from 1997 re: CD-ROMS):

Again, thank you. Scanning this one is more difficult, but leads to the
following:
1. No conclusions are drawn
2. The properties of the tested discs are not given
3. For those discs, accelerated life tests as defined here seem appropriate
It is a substantial stretch - though again there is no other guideline - to
assume that 3. above applies to a specific modern medium. I interpret the
document as defining a test procedure by which a candidate medium can be
measured. Are there studies reporting results using the procedure/standard?
Or am I misreading the document and its purpose?
