Penetrameters are found in x-ray, these are the things placed on a weld with holes or wires of various sizes to show that the x-ray film has acceptable sensitivity.

Not sure about calibrating them. Usually manufacturer will supply certificate of conformity.

Unless its something completely different

I dont think there is a an ASME code reference for this.

ASTM E-747 and E-1025 (both referenced in ASME V and ASTM E-94) describe design, manufacture and material grouping classification for wire and hole-type Image Quality Indicators (penetrameters), respectively.

As HouseHark says, a certificate provided at time of purchase confirming conformity to these standards should be sufficient evidence for an auditor. Hope to be corrected if I am wrong.

All I've ever done with penetrameters if there was any question we would have them measured in our development lab.
This was usually done with a comparator and electronic mikes. The only real problem I've encounter was a radiographer grahiting the holes.
