4.3 Inspection provisions
4.3.1 Lot formation.-The term "inspection lot" as used
in 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 represnt any
prior or subsequent quantities presented for inspection.
Homogeneity shall be considered to exist provided the
inspectionlot has been produced by one manufacturer, in one
unchaged process, using the same materials and methods, in
accordance with the same drawings, same drawing revisions,
same specifications and same specification revisions, and
complies with the provisions for submission of product as
specified in MIL-STD-105. Changes to the process,
specifications, or drawings 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
accordance 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 munbering, as reuqired,
shall be in accordance with MIL-STD-1168.
