4.3 Inspection provisions for production
4.3.1 Lot formation. - The term "lot" as used throughout this
specification refers to an Inspection lot, which 3.s defined as
an essentiality homogeneous collection of units of product from which
a representative sample is drawn and inspected to determine
conformance of the lot with applicable requirements. The sample
selected shall represent only that quantity of units from which
the sample was drawn and shall not be construed to represent any
prior or subsequent quantities presented for inspection. Homoge-
neity shall be considered to exist provided the lot has been
produced by one manufacturer, in one unchanged process, in
accordance with the same drawing, specification, or revision
thereof. Changes to either the process, specification, or drawing
not affecting safety, performance, interchangeability, or storage,
as determined by the Government, shall not be deemed to alter the
homogeneity of the lot. Inspection lots shall comply with
MIL-STD-105 and shall be numbered in accordance with MIL-STD-1168.
Unless otherwise approved by the contracting officer, the
inspection lot size of major assemblies or end items deliverable
under the contract shall be not less than the smallest weekly
estimate of quantities contractually scheduled for production
during the contract period nor more than the largest quantity
contractually scheduled for delivery during any month of the
contract period. Inspection lots for components or sub-assemblies,
other than the items of delivery, shall be homogeneous and of a
size convenient to the contractor.
4.3,2 Examination, - Sampling plans and procedures for the
following classifications of defects shall be in accordance with
Standard MIL-STD-105 except that inspection for critical defects,
when listed, shall be 100 percent. Continuous sampling plans in
accordance with Standard MIL-STD-1235 may be used if approved by
the procuring activity. Also, at the option of the procuring
activity, AQL's and sampling plans may be applied to the indivi-
dual characteristics listed using an AQL of 0.40 percent for each
major defect and an AQL of 0.65 percent foe each minor defect.
Once agreement has been reached as to which method will be used
(group or individual) that method will be used for all of the CD'S
listed in this specification. Equipment necessary for the per-
formance of the inspections listed shall be in accordance with
