We currenty use a Pratt & Whitney Model A supermic. it does have a new head that will give it pretty good accuracy and repeatability, but we use it to calibrate our plug gages and such, was just wondering what kind of accuracy requirements there are for ISO9k

I do not believe there is a specific ISO9000 accuracy requirement. The requirement is for NIST traceability, and adequate test uncertainty ratio (4:1). That may be a vast oversimplification, but that is the gist.
