Tape and Reel Flatness?

Greetings,

Does anyone know where to find a tape and reel flatness specification? Looking at the EIA 481-B standard, there is no reference to the tape flatness (the images shown may "imply" flatness from one side of the tape to the other, However I do not actually see a flatness spec.). We currently have an issue with one of our tape and reel part pocket tape side. There is an approx. 1mm downward angle on the edge, which creats interference in the feeder (16 mm).

Anyone have a known reference to a flatness spec?

Thanks in advance.

Jer
