If the border is at some point straight across from (on the same horizontal plane as) the RP, use the
overspray gauge to locate the actual border line (para 4-13d) where border intersects RP's horizontal plane.
Mark point on border line where it intersects this plane, and measure distance from this point to RP.
If border is not on same horizontal plane as RP (see figure 4-4 for example), drop a plumb bob from the
higher point, and measure distance from lower point to that point where its horizontal plane intersects plumb line. (Again,
the overspray gauge can help distinguish the actual border line (para 4-13d(2).)
Vehicle must be level to get accurate measurement.
This distance must be within + 1 inch of the LD on worksheet. If it is not, document a level III failure in
same way as level II failures (para 4-13d(3)(a)-(g)).
BWs. A BW on the inspection worksheet (figure 4-4) is a dimension (in inches) with arrows and lines from a point
on a black band border to a point on an opposite border of same black band. Check these as follows:
Locate BW on worksheet. Note points on opposite borders of same black band.
Go to equipment and locate corresponding points on actual applied borders.
Use overspray gauge to distinguish each actual border line (para 4-13d(2)).
Measure distance between these lines at points corresponding to those marked on worksheet.
If this distance is not within + 1 inch, document level III failure in same way as level II failures (para 4-
Level III Inspection Completion. This level of CPP inspection is complete when at least one point on each black
band border in each view of the equipment has been checked to ensure its location is within ± 1 inch of that specified on
the drawings. Checking each LD, delta and BW on the inspection worksheet minimally fulfills this requirement; however,
additional measurements may be made to increase confidence levels at discretion of inspector. Inspector must witness
and accept correction of all failures found.
4-15. COMPLETION OF FULL CPP INSPECTION
The CPP inspection is complete when all three levels of inspection are complete.
4-16. SUMMARY OF CPP INSPECTION REQUIREMENTS
Inspection requirements vary with the method of CPP application. As stated in Section II, robotic and template methods
require the first applied pattern to pass inspection (all levels), thereby making that robotic program or template certified.
Subsequent patterns applied using that program or template shall be inspected on a random sample basis. Manual and
projection methods require each and every applied pattern to be inspected (all levels).
