6.2 Order data. Acquisitioning documents should specify the following:
a.
Title, number, and date of this specification.
b.
Model(s) to be acquired (see 1.2).
c.
Preproduction model(s) if required (see 3.1).
d.
Initial production sample(s) if not required (see 3.1.1).
e.
Whether welding repair is authorized and extent allowed (see 3.4.3.2).
f.
Need for reconditioning test vehicles (see 4.4.1.1 and 4.7).
g.
Information to be shown on data plates (see 3.6.3).
h.
Selection of applicable levels of protection (see 5.1).
6.3 Sampling of trailers. Sampling inspection of trailers may be initiated by the production
contractor only upon receipt of written authorization from the Government acquisitioning activity.
In the event the Government authorizes sample inspection of the end item, the production
contractor must then meet the sampling criteria specified in 4.5.4. Sample inspection of
components or materials however, is at the discretion of the contractor. Such sampling must be in
accordance with sampling plans of applicable military standards and must be part of the contractor
Quality Assurance System approved by the Government.
6.4 Process average. Sampling may be initiated when authorized by the Government
acquisitioning activity (see 6.3) and when the process average value for 20 consecutive trailers
inspected is less than the AQL specified in the classification of defects for major and minor
defects.
Process average shall be computed as follows:
Process average =
Number of defects
X100
Number of trailers inspected
If the computed process average exceeds the specified AQL, 100 percent inspection shall be
performed and continued until such time that the process average for 20 consecutive trailers is
less than the specified AQL.
6.5 Definitions of recurring major and minor defects. The Government Inspector will verify
that a thorough inspection of each trailer is performed by the contractor not only for the listed
characteristics (see tables IV, V and VI), but also for any other departures from good
workmanship. The Government Inspector will assure that all deficiencies encountered during the
inspection are enumerated on the deficiency sheet for the semitrailer. The defects noted on the
deficiency sheet shall contain sufficient description to enable the Government inspector and the
contractor representative to classify the deficiency in accordance with the classification of defects
of the semitrailer specification and definitions contained in MIL-STD-105. Corrective action shall
be taken for recurring deficiencies.
