I would need more information on the tolerance before I could give an answer.
First, if it is a "typical" tolerance of ±0.015" that is what it should be, not what it must be. You can't really call a "typical" device out of specification since it is not a warranted tolerance...
Also, assuming that this might be a warranted tolerance, is it over the full range of the device (60")? Or is there also a linearity specification (such as 0.005" per 12") in addition.
