(b) All inspections require the viewing of external preserved surfaces. This requires lifting of opaque
shrouds or dust covers and the removal of tops or covers not secured to individual boxes or containers.
Deviation from a 100 percent per month visual inspection is not permitted.
(d) If visual inspection indicates the formation of deterioration of the preservative in excess of 10 percent
of all items, a periodic inspection shall be performed on all affected items. Corrective actions shall be taken immediately
when unsatisfactory conditions are found.
(8) Noncontrolled humidity storage-periodic inspection. No periodic inspections are required on items of IPE
that have been in storage 6 months or less. Periodic inspections of IPE shall be scheduled for the seventh month of
(a) The number of items of IPE and OPE to be inspected per year shall be of such size to include a total
inventory over a 3 year period (assume static condition for each year's sample).
(b) Items of IPE and OPE shall be scheduled for periodic inspections every 3 years. The inspection shall
include all types of items not previously inspected within the last 3 years.
(c) The inspection procedures to be followed for noncontrolled humidity storage-periodic inspection are the
same as those outlined in 6-6e(2)(c) through (f) above.
(9) Noncontrolled humidity storage-detailed inspection. There is no requirement for detailed inspection of items
of IPE and OPE in storage during the first 3 years unless there is evidence of deterioration of the preservative and/or
(a) After 3 years of noncontrolled humidity storage, detailed inspections shall be performed annually to
include 10 percent of the total inventory among all types of items. If results are unsatisfactory, a special study shall be
made to correct unsatisfactory conditions.
(b) The inspection procedures to be followed for nonhumidity storage-detailed inspection are the same as
those outlined in 6-6e(3)(b) through (d).
Recording of Inspection Results
a. The results of each inspection are important since they can be used to determine the influence of such factors as
geographical location, type of storage, machine design, size of installation, type of housing, or the quality of preservation.
This type of information is needed to effect future economies in storage techniques and to formulate a concise and
specific sampling plan.
b. A record of the results is also important for charting the progress of sampling and inspection activities. It is
essential that inspection results are carefully recorded and that the data and terminology are standardized as much as
