Acceptance Criteria for calibration of eddy current equipment

[QA Man]

Is there a published ASTM standard to use in determining acceptance/rejection of an eddy current unit from an ISO 17025 Accredited Lab. Our EASA audit is coming due and I have been informed that this is one of their issues this year.

If you look in the practice spec (the E spec) it should comment on this.
For our electronics calibrations we rely on the equipment manufacture.
They have standard response curves for the detection circuits.
