Lot Formation. - The term “inspection lot“
36、 as used in this spec fication is defined as an essentially homogeneous col- lection o units of product from which a representative sample is drawn and inspected to determine conformance wi th applicable requi rements. The sample selected shall represent only that quantity of units from which the sa
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. Each inspection lot of loaded detonators chal 1 contain: a. Metal parts from not more than one lot interfix b. PETN of one lot from one supplier. c
