quantity of units from which the sample was drawn and shall not
be construed to represent any prior or subsequent quantities
presented for inspection. Homogeneity shall be considered to exist
provided the inspection lot has been produced by one manufacturer,
in one unchanged process, in accordance with the same drawing,
same drawing revision, same specification and same specification
revision and complies with the provisions for submission of product
as specified in MIL-STD-105. Changes to process, specification, or
drawing not affecting safety, perfomance, Interchangeability, or
storage, as determined by the Government, shall not be deemed to
alter the homogeneity of an inspection lot. All material submitted

with the homogeneity criteria specified herein regardless of the
type of sampling procedure which is being applied to determine
conformance with requirements. Lot numbering, as required, shall
be in accordance with MIL-STD-1168.

when so specified) shall be 100 percent. Sampling plans for major
and minor defects shall be in accordance with MIL-STD-105 except
that continuous sampling plans in accordance with MIL-STD-1235 may
be used if approved by the Government. Instead of applying the

listed, the contractor may elect to apply AQL's to Individual de-
fects using an AQL of 0.40 percent for each major defect and an
AQL of 0.65 percent for each minor defect. When this method is
elected, it shall be applied to all of the major and minor defects
listed in the applicable subparagraph of this section, except
