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 inspection l
24、ot 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
25、, or drawing not affecting safety, performance, mterchangeability, or storage, as determined by the Government, shall not be deemed to alter the homogeneity of an inspection lot.
