28、inspection lot“ as used in this spec- ification is defined as an essentially homogeneous collection of units of product Prom which a representative sample is drawn anel inspected to deter- mine conformance with appli cable requi rements. The sanple selected shall represent only that quantity of unit
29、s from which the sample was drawn and shall not be construed to represent any prior or subsequent quantities pre- sented for i nspectisn.

30、e drawing, same draiing revision, same specification and same specification revision and complies with the provi- sions for submission of product as specified in Mit-STD-105. Changes to the process, specification or drawing not affecting safety, performance, interchangeability or storage, as determi
31、ned by the Government, shall not be deemed to alter the homogeneity of an inspection lot. All material sub- mitted 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 d

34、 Inspection for Critical Defects (and Major Defects, 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 .saw1 i ng plans i n accordance with MI L-STD-1235 may be used if approved by the .Government. desi
35、gnated herein to the groups of Major and Minor Defects listed, the con- tractor may elect to apply AQLs to individual defects using an AQL of 0.40 percent for each Major Defect and an AQL of 0.65 percent for each Minor Ue- fect. When this method is elected, it shall be applied to all of the Major an
36、d Minor Defects listed in the applicable sub-paragraph of this section, except where 100 percent inspection is specified, and be documented as part of the contractors inspection system.
