Pres- sure springs, pull springs, firing pin springs and release pin springs shall not break when extended to the minimum point of perma nent distortion when tested as specified
9、in 4.4.3. 3.4 Nonfunctioning. The metal parts as- sembly shall not function when a load, not to exceed 3.0 pounds, is applied to the re- lease pin ring parallel to the axis of the release pin and when a load, not to exceed 8.0 pounds, is applied to any one prong or equally distributed upon all three
10、 prongs parallel to the axis of the assembly when tested as specified in 4.4.1. 3.5 Functioning. The metal parts as- sembly shall function when a load, not to exceed 10 pounds is applied to the release pin ring parallel to the axis of the release pin and when a load, not to exceed 20 pounds is appli
11、ed to any one prong or equally distributed upon all three prongs parallel to the axis of the head assembly. The test shall be performed as specified in 4.4.2. 3.6 Workmanship.

In- spection Equipment Lists indicate the avail- ability of inspection equipment designs by showing in the ?number? column of the list of inspection equipment (O0 Form 12423) the numbers of drawings of exis?ing eq
14、uip- ment designs or codes as indicated in 6.3.2. Design action required of the contractor with respect to the different types of draw- ings that may be listed is described in 6.3.3 and 6.3.4. Action required by the contrac- tor with respect to commercial inspection equipment is described in 6.3.6.
15、The con- tractor will be required to prepare detailed drawings in accordance with 6.3.6 for all the equipment coded as ?contractor design? in the number column. Those contractor designs must be approved by the Govern- ment prior to fabrication or procuring of the equipment. Designs shall be submitte
16、d 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, 6.3.6, and 6.3.6 will be designated in the Inspection Equipment List by the for- lowing codes : CDOF - Contractor?s design respon- sibility on Ordnance for- mat; ORDM-608
17、-12. CDCF - Contractor?s design respon- sibility on contractor for- mat. OD - Ordnance design. ODMU - Ordnance design, ma n d a - tory for use. CE - Commercial equipment. SCD - Specification Control Draw- ing. 6.3.3 Ordmtzce designs. Ordnance de- signs are reflected on detailed drawings which comple
18、tely depict all the information necessary for the fabrication of the item Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-1 / of inspection equipment. The contractor need provide no design when an Ordnance design is listed for an item of inspection e
19、quipment. Ordnance designs fall into two basic classifications ; mandatory and non- mandatory. When an Inspection Equip- ment List references mandatory Ordnance designs, the contractor shall comply with, and use these designs accordingly. The contractor may, however, in connection with nonmandatory
20、designs and with the ap- proval of the Government, design alternate inspection equipment or use comparable commercial equipment to facilitate his op- erations. Such contractor prepared designs or commercial equipment selections must be approved by the Government prior to fab- rication or procuring o
21、f the equipment. De- signs shall be submitted for approval as specified in 6.3.7. 6.3.4 Specification control drawings. Specification control drawings depict the minimum equipment requirements in out- line, descriptive, diagrammatic, or pictorial form only and specify the required perform- ance or o
22、ther characteristics. Contractors must prepare detailed drawings (see 6.3.6) of their designs in support of specification control drawings. These contractor pre- pared designs must be approved by the Government prior to the fabrication or procuring of the equipment. Commercial equipment meeting the
23、requirements of specification control drawings may be ap- proved if described in sufficient detail to permit identification and evaluation by the Government, Designs shall be submitted for approval as specified in 6.3.7. 6.3.5 Commerd equipment. Commercial equipment is inspection equipment that has
24、universal application for a specific function. It is comprised of items commonly used by industry and governmen. Contractors are not required to furnish drawings of commercial inspection equipment but a list of such equipment must be approved by the Government. Lists shall be submitted for MIL-F-600
25、20() approval to the inspection element of the agency administering the contract. 6.3.6 Contractor designs. Contractor de- signs are designs of inspection equipment for which the Government has assigned design responsibility to the contractor. Con- tractor designs shall be supported by de- tailed dr
26、awings which depict all information necessary to completely fabricate, calibrate and operate an item of inspection equip- ment. This requires that the necessary views, dimensions, materials, finish, notes, operating and calibration instructions be properly depicted in accordance with ap- proved prac
27、tices to the extent that further calculation or clarification will not be re- quired. Contractor designs identified as CDCF may be developed on the format the contractor normally employs in his equip- ment design procedure provided such format reflects the detail and information specified above. Con
28、tractor designs identified as CDOF shall comply with the format and re- quirements of ORDM 608-12, and, in addi- tion, contain the detail and information specified above, 6.3.7 Subm.isson of contractor designs. Designs shall be submitted for approval to the Commanding Officer, Picatinny Arsenal, ATT
29、N: SMUPA-ND. Design review will normally be accomplished within one month after receipt by Picatinny Arsenal. Partial submission of inspection equipment designs is permissible and encouraged. However, the Arsenal completion date for design re- view will be based on the date of the final submission o
30、f designs, 6.4 Functioning. The fuze assembly, less igniter assembly, shall be considered to have functioned if the firing pin is re- leased and capable of clearing the assembly when tested. 6.5 Submission of critical defect reports.
