37、mple was drawn and shall not be construed to represent any prior or subsequent quanti ties presented for inspection. Homogene ty chal 1 be considered to exist provided the inspection lot has been produced by one manufacturer, in one unchanged process, using the sam materials and methods, in accord-

38、ance with the same drawings, same drawing revisions, same specifi- cations and same specification revisions, and complies with the provisions for submission of product as specified in Standard MIL- STD-105. Changes to the process, speci f cat ions or drawings not affecting safety, performance, inter

39、changeability or storage, as determined by the Government, chal 1 not be deemed to al ter the homogeneity of an inspection lot. All material submitted for in- spection in accordance with this specification shall comply with the homogeneity criteria specified herein, regardless of the type of samplin

40、g procedure which is being applied, to determine con- formance with requirements. Lot numbering, as requi red, shall be in accordance with MIL-STD-1168.
