and the actual TSC/PPC is Level 5, Code A, the net change would be +3, and the new IFC would be 4. It must be noted

that when applying this curve some approximations will be necessary (as indicated in the example) to yield round numbers

as the IFC adjustment is being performed on codes. Also, for some items certain changes of protection will yield a code

greater than 6, or less than 1. In such cases, the new inspection frequency code shall be limited to those bounds.

h. Test Required (TRC). The Test Required column contains a code describing the method by which an item is to be

inspected. Specific codes used in identifying these inspection methods are given in table 2-7.

In most cases, the test required shall consist of a visual examination (91V). Visual inspections are formulated to assure

with minimum effort the readiness of a given item or component for use. Further, appendix A (QDC) column identifies all

criteria necessary to the performance of these inspections. For this reason the visual inspection is limited to surface

examinations for defects of a gross and easily identifiable nature. In other cases, further inspection is required. In these

cases attention is directed to appendix B of this Supply Bulletin. Appendix B provides supplementary requirements,

instructions and/or clarification of the appendix A coded requirements. Typically, such instructions might consist of

sampling, storage, handling, and data reporting. Appendix B may also be called out when a detailed, step-by-step

inspection procedure is required.

i. Preservation Packing (PPC). The Preservation Packing column contains a code describing the preferred level

and/or most cost-effective level of protection for each item. These codes are identified in table 2-8. The packaging codes

listed in the PPC column of appendix A are not prescriptive; they are used, however, to set the inspection frequency (IFC).

If material is placed in storage at a level other than that indicated in the standard, the inspection frequency may be

adjusted (unless restricted by appendix A) as described in paragraph 2-2g. After an item has been inspected and

accepted, the packaging/preservation is to be restored to its pre-inspection level. Further, the date of repackaging, as well

as the date of original packaging, shall be stamped on the package.
