15、d by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3.2 Style, desiqn and dimensions. The orceps shall be a ringed clip applying forceps suitable for holding and the application o small size hemostatic clips. The forceps shall be approximately 7-1/2 inches in l
16、ength with the distal clip holding jaw at a 15 degree angle to the handles. The handles shall be color coded to match the color coding of the hemostatic clips. The forceps shall be in strict accordance with DelEense Personnel Support Center (DPSC) Drawing 23350. The forceps shall have a spring betwe
17、en the handles so that the forceps are held in the Eully open position. The forceps shall contain a mechanism that limits the opening of the distal tip jaws to the maximum opening as shown on DPSC Drawing 23350. The tip of the jaws shall close first and the clip holding section shall be the only par
18、t o the jaws to close completely. 3.3 Material. The forceps shall be fabricate from Class 4, martensitic etainless steel in accordance with ASTM F899. 3.4 Hardness. Forceps shall have a Rockwell hardness o C40 to C47 when tested as specified in 4.4.1. The requirements of GG-1-526 tmii apply. 3.5 Pas
19、sivation. The forceps shall be properly passivated. 3.6 Clip retention. When tested as specified in 4.4.2, the clips shall not fall out of the jaws of the forceps when the forceps are held with jaws vertically downwmd. 3.7 Performance. When tested in accordance with 4.4.3, the orceps shall close the
20、 clips as specified. 3,8 Lucks. Shall be of box lock type. The box lock construction shall be accuEately fitted, and shall be without crevices, burrs, or sharp edges at any place in the lock construction. permanently secured. The joint performance shall be smooth, of equal resistance, and non-bindin
21、g in all positions when opening or closing the orceps (the lock may be lubricated). Further, under no circumstances shall looseness or free play of either shank permit any misalignment of the jaws in closing. NOTE: This paragraph shall replace the requirements specieied in GG-1-526 for locks. Pin or
22、 rivet shall 3.9 Finish. Finish shall be entirely mirror, satin or matte. Should the forceps be of mirror finish, the locks and ratchets shall be polished smooth, but need not possess a mirror finish. The matte einfeh shall exhibit a uniform non-directional surface texture equivalent to that produce
23、d by lightly blasting the prepared surface with Eine abrasives under pressure. 3,J.O Identification markinq.

29、 Inspection, as used in this specifcation, is defined as both examination (such as visual, auditory, etc. investigation without the use of special laboratory appliances or procedures) and testing (determination by technical means of physical and chemical properties), of the item. 4.1.3 Records. Reco
30、rds of examinations and tests performed by or for the contractor shall be maintained by the contractor and made available to the Government, upon the Governments request, at any time, or from time to time, during the performance of the contract an( for a period of 3 years after delivery of the suppl
31、ies to which such records relate. The inspection set forth in this Sampling in quality conformance does not authorize 4.1.4 Certificates of quality. Certificates of quality supplied by the manufacturer of the corrosion-resistant steel may be furnished in lieu of actual performance of such testing by
32、 the contractor, provided lot identity has been maintained and can be demonstrated to the Government. The certificate shall include the name of the contractor, the contract number, the name of the manufacturer or - supplier, the National Stock Number, the item identification, the lot number, the lot
