SIE designs are designated by drawin

31、g numbers under the “Nethod of Inspection“ headings in Section 4. Design responsibility for all other inspection equipment is assigned to the contractor. The contractor need not furnish any design when a complete Govern- ment SIE design is provided. Unless otherwise specified, how- ever, the contrac

32、tor may submit alternate or modified con- tractor designs of SIE in accordance with 6.3.2 and 6.3.3 should he elect to do so. 6.3.1 SIE designs.-SIE designs may consist of any of the foiloNing: a. Detailed drawings which completely depict all infor- b. A source control drawing or a specification con

33、trol c.

The contractor must include in his sub- mission of designs a listing of any and all Government SIE designs which will be utilized. Partial subm

41、ission of inspec- tion designs is permissible and encouraged. However, the . completion date for design review will be based on the date of the final submission of designs. Picatinny Arsenal design review will normally be accomplished within one month after receipt. *6.4 The margins of this specific
