The five digit code numbers assigned to the inspections herein are to facilitate future data collection and analysis by the Government. 6.3 Inspection equipment. The contractor shall des

28、ign inspection equipment as required by the referenced Inspection Equipment Lists (IEL) in accordance with the instruc- tions of paragraphs 6.3.1 through 6.3.7. 6.3.1 Inspection equipment lists. Inspec- tion equipment lists indicate the availability of inspection equipment designs by showing in the

29、“number” column of the list of inspec- tion equipment (O0 Form 1242-3) the num- bers of drawings of existing equipment de- signs or codes as indicated in paragraph 6.3.2. Design action required of the contrac- tor with respect to the different types of drawings that may be listed is described in par

30、agraphs 6.3.3 and 6.3.4. Action required by the conractor with respect to commer- cial inspection equipment is described in 6.3.5. The conractor will be required to pre- pare detailed drawings in accordance with 6.3.6 for all the equipment coded as “Con- tractor Design” in the number column. These c

31、ontractor designs must be approved by the Government prior to fabrication or procuring MILC-13473C (MU) of the equipment. Designs shall be submitted for approval as specified in 6.3.7. 6.3.2 Inspection equipment list codes. The inspection equipment as defined in 6.3.3, 6.3.4, 6.3.5 and 6.3.6 will be

32、 designated in the IEL by the lollowing codes: CDAF - Contractors design responsi- bility on Army format in accordance with MIGD- 45608.

Army designs are re- flected on detailed drawings which completely depict all the information necessary for the fabrication of the item of inspection equip- ment. The contractor need provide no design when an Army design is listed for an item of inspection eq

34、uipment. Army designs fall into two basic classifications, mandatory and nonmandatory. When an inspection equipment list references mandatory Amy designs, the contractor shall comply with, and use these designs accordingly. The contractor may, however, in connection with nonmandatory designs and wit

Contactors must prepare de- tailed drawings (see 6.3.6) of their designs in support of specification control drawings. These contractor prepare

38、d designs must be approved by the Government prior to the fabrication or procuring of the equipment. Commercial equipment meeting the require- ments of specification control drawings may be approved if described in sufficient detail to permit identification and evaluation by the Government. Designs

39、shall be submitted for approval as specified in 6.3.7. 6.3.5 Cornmerda1 equipment. Commercial equipment is inspection equipment that has universal application for a specific- function. It is comprised of items commonly used by industry and Government, Contractors are not required to furnish drawings

40、 of commer-i cia1 inspection equipment, but a list of such equipment must be approved by the Govern- ment. Lists shall be submitted for approval to the inspection element of the agency ad- ministering the contract. 6.3.6 Chtractor designs. Contractor de- signs are designs of inspection equipment for

41、 which the Government has assigned design responsibility to the contractor. Contractor designs shall be supported by detailed draw- ings which depict all information necessary to completely fabricate, calibrate and oper- ate an item of inspection equipment. This requires that the necessary views, di

42、men- sions, materials, finish, notes,. operating and calibration instructions be properly depicted in accordance with approved practiws to the extent that further calculation or clarifica- tion will not be required. Contractor designs identified as CDCF may be developed on the format the contractor

43、normally employs in his equipment design procedure provided such format reflects the detail and informa- tion specified above. Contractor designs iden- tified as CDAF shall comply with the format and requirements of MIL-D-45608, and in addition, contain the detail and information specified above. Fi

44、nal approved contractor designs identified as CDCF shall be suitable for microfilming. They must be nonrepro- ducible diazo or electrostatic prints of top quality full size with black line on white background and shall provide a legible print produced via the 35MM microfilm process. Contractor shall

45、 submit one copy of the final design as a rolled set or flat set. 6.3.7 Submis&crn of contructor designs. De- signs shall be submitted for approval to the Commanding Officer, Picatinny Arsenal, ATTN: SMUPA-ND. Design review will nor- mally be accomplished within one month after receipt by Picatinny

46、Arsenal. Partial submission of inspection equipment designs is permissible and encouraged. However, the Arsenal completion date for design review will be based on the date of the final submis- sion of designs. 6.4 Clean scrap. Clean scrap is defined as scrap formed in kettles, pails, risers and load

47、- ing machines used in pouring and cooling operations, and scrap formed in the drilling operation. 6.5 Penetration. Complete penetration is defined as a hole completely through the plate and free from obstructions. However, the lodging of a copper slug in the completed hole is not considered cause f

The contracting officer shall arrange for the contractor to be reimbursed for the expense incurred in the perfomance of the ch

49、eck tests. The test shall be conducted at Govenment expense without cost to the contractor who loaded the primers or to the contractor assembling the cartridge, and shall not constitute a basis for rejection against either contractor, except where de- terioration has occurred as a direct result of carelessness in handling, storage, etc., per- 14 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-13473C 13 B 7977906 0295366
