31、 the per- centage of normal le types of drawings that .may be listed is described in paragraphs 6.3.3 and 6.3.4. Action required by the contractor with respect to commer- cial inspection equipment is described in 6.3.5. The contractor will be required to pre- pare detailed drawings in accordance wit

32、h 6.3.6 for all the equipment coded -as “Con- tractor Design” in the number column.

35、 on detailed drawings which complete- ly depict all the information necessary for the fabrication of the item of inspection equipment. The contractor need provide no design when an Army design is listed for an item of inspection equipment. Army de- signs fall into two basic classifications, man- dat

36、ory and nonmandatory. When an inspec- tion equipment list references mandatory Army designs, the contractor shall comply with, and use these designs accordingly. The contractor may, however, in connection with nonmandatory designs and with the approval of the Government, design alternate inspec- tio

37、n equipment or use comparable commer- cial equipment to facilitate his operations. Such contractor prepared designs or com- mercial equipment selections must be ap- proved by the Government prior to fabri- cation or procuring of the equipment. De- . signs shall be submitted for approval as specified

38、 in 6.3.7. 6.3.4 Specification control drawing. Speci- fication control drawings depict the mini- mum equipment requirements in outline, de- scriptive? diagrammatic or pi&orial form only and specify the required performance or other characteristics. Contractors must prepare detailed drawings (see 6.

39、3.6) of their designs in support of specification con- trol drawings. These contractor prepared designs must be approved by the Govern- ment prior to the fabrication or procuring of the equipment. Commercial equipment meeting the requirements of specification control drawings may be approved if de-

40、ecribed in sufficient detail to permit identi- fication and evaluation by the Government. Designs shall be submitted for approval as specified in 6.3.7. 6.3.5 Commerczal equipment. Commercial equipment is inspection equipment that has universal application for a specific function. It is comprised of

41、 items commonly used by industry and Government. Contractors are not required to furnish drawings of com- mercial inspection equipment, but a list of such equipment muit be approved by the Government. Lists shall be submitted for approval to the inspection element of the agency administering the con

42、tract. 6.3.6 Confiador dedgns. Contractor de- signs are designs of inspection equipment for which the Government has assigned de- sign responsibility to the contractor. Con- tractor designs shall be supported by de- tailed drawings which depict all infornahm necessary to completely fabricate, calibr

43、ate and operate an item of inspection equipment. This requires that the necessary views, di- mensions, materials, finish, notes, operating and calibration instructions be properly de- picted in accordance with approved practices to the extent that further calculation or clarification will not be req

44、uired. Contractor designs identified as CDCF may be devel- oped on the format the contractor normally employs in his equipment design procedure provided such format reflects the detail and information specified above. Contractor de- signs identified as CDAF shall comply with the format and requireme
