(2)
Record failure on inspection worksheet.
(3)
Describe failure in notebook for painter/contractor debriefing.
(4)
Report failure in specific detail to painter/contractor to facilitate correction. Reference points may be used to
show failure location.
(5)
Provide constructive guidance on corrective action (e.g., inspector may even draw correct contour line on item
and direct repainting within this line).
f.
Repeat c through e for the other four drawing views. Level I inspection is complete when each view is examined
in this manner, and when all corrections have been witnessed and accepted by inspector.
4-13. LEVEL II INSPECTION
In this level of inspection, the borders are examined to ensure color definition. The contrast between color areas is key to
CPP effectiveness, and, for this reason, overspray of one color into another color area must be minimized to a 1-1/2 inch
tolerance. An overspray gauge (figure 4-3) is used to determine whether overspray on the applied CPP is within this
narrow tolerance.
a.
Overspray. Unless applied robotically, pattern colors are applied in sequence, beginning with a base coat in the
primary color (#2 on CPP drawings). The other two color patches/bands are spray-painted, one after the other, over this
base coat. A normal result of this process is overspray, the overlapping mist of one paint color on an adjacent color area
which impairs CPP effectiveness. With experience, painters can minimize overspray.
b.
Overspray Gauge. The overspray gauge (figure 4-3) is a card-like, transparent sheet of plastic with white
markings (to contrast with camouflage colors) which indicate the tolerance, or 'transition' zone. The gauge is overlayed on
the border area; the actual border line is then located and aligned under the gauge boundary line DESIGNATOR, and the
overspray is examined. When overspray extends into the 'FAIL ZONE', the failure location is noted by marking the
notches at both ends of the gauge boundary line DESIGNATOR with chalk or soapstone.
c.
Areas to be Inspected. Level I inspection included a visual check from a distance of contour definition. Any areas
noted where contours were NOT sharply defined should be inspected for overspray failure. Special attention should be
given to black disruptive bands, which are especially important to CPP effectiveness.
d.
Level II Inspection Procedure. For each area noted as in sub para c, complete the following steps:
(1)
Lay overspray gauge over border, so that FAIL ZONE lays over color area applied first.
(2)
Align DESIGNATOR, or boundary line marking, as close as possible to fog/boundary transition area, so that
it is just short of overlapping spray, but so that no primary color can be seen in secondary section.
(3)
Examine overspray. If it extends into FAIL ZONE, record Level II failure as follows:
(a)
Mark notches at both ends of DESIGNATOR line on gauge with chalk or soapstone.
(b)
Record overspray failure on inspection worksheet.
(C)
Make descriptive entry in notebook for painter/contractor debriefing.
(d)
Report overspray failure in specific detail to painter/contractor. Show failure location.
(e)
Provide constructive guidance on corrective action.
