It is therefore recommended that supplier inspection reports are not used as the sole
basis of a part check during a quality investigation. Instead, wherever possible the
engineer should carry out the part investigation in the PG him / herself, making sure
that the gauge set up is correct, observing parts behaviour before and after clamping
and taking specific measurements in the concern areas, (not only standard check
points). A detailed method for measuring parts in the PG is included in section 5.2 of
this document.
