Code

Frequency (Months)

No Test

It must be noted that this code reflects an inspection time period based upon the preferred storage environment, and

PP&P materiel and methods given in the PPC and TSC columns, respectively (see also paragraphs 2-2i and 2-2j).

However, when individual depot constraints are such that the actual PP&P and storage environment differ from that given

in the PPC and TSC columns, adjustments to the time period must be made.

Figure 2-1. Inspection Frequency Adjustment

(2) A Curve Depicting Frequency Adjustments is Given in Figure 2-1.

Application of this curve to an item is illustrated by the following example. Assume for a given item that the TSC and PPC

columns of appendix A indicate TSC (Level 5), PPC (Code A), and an IFC of 4 (30 months). Next, assume that the actual

TSC and PPC is (Level 5) (Code B). By drawing a line up from TSC/PPC 5A and 5B, to intersect the curve and then

across from the points to the IFC adjustment, as illustrated, an approximate net change of -3 is obtained. Then 3 must be

subtracted from 4 to yield a new inspection frequency code of 1 (6 months). It should be noted that when actual TSC/PPC

protection is less than recommended, the IFC adjustment will be minus, indicating less protection and more frequent

inspection. Conversely, if the TSC and PPC columns of appendix A indicated Level 5, Code B with an IFC of 1,
