4.3.1 Lot Formation. The term "inspection lot", as used
throughout this specification, is defined as an essentially
homogeneous collection of units of product from which a
representative sample is drawn and inspected to determine
--
conformance 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. Homogeneity
shall be considered to exist provided the lot has been produced
by one manufacturer, in one unchanged process, in accordance
with the same drawings, same drawing revisions, same specifications
and same submission of product as specified in MIL-STD-105. Changes .
to 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 an
inspection lot. All material submitted for inspection in accord-
ance with this specification shall comply 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. Each inspection lot shall bear a unique lot
number.
4.3.2 Examination. The examination listed in this detail
specification for Classification of Defects (and tests) shall be
performed on inspection lots as defined in 4.3.1 of this
specification.
a. Sampling Plans. Sampling plans for Major and Minor
Defects shall be in accordance with MIL-STD-105, except that
variables sampling plans in accordance with MIL-STD-414 or con-
tinuous sampling plans in accordance with MIL-STD-1235 may be
used if requested by the contractor and approved by the
Government.
b. Critical Defects. Unless otherwise specified,
inspection for Critical Defects shall be 100 percent (%) .
