Testing is described

42、in the First Article and Quality Conformance Inspection Tables and the following: 4.4.3.1 ,Cavitation (see 3.4, except 3.4.5) . Cavitation defects are classified as follows: Cri tical: 1. Cavitation, cracks, piping, porosity or annular rings in segment A or B in excess of that permitted in Table I.

43、2. Cracks in excess of that permitted ijy 3.4.2. 3. Base separation (see 3.4.4) This test shall be performed on all loaded ogive assemblies (100 percent inspection) . The radiographic test shall be performed as specified in 4.5.1 using equipment in accordance with 4.4.4. Any ogive which has any one

44、of the above critical defects shall be classed defective and removed from the lot. 4.4.3.1.1 Base separation. The base separation inspection shall be performed either by sectioning of selected ogives (44.3.1.1.1) or by use of a radiographic standard (4.4.3.1.1.2) 4.4.3.1.1.1 Oqive sectioninq. Ogives

45、 showing the largest base separation as determined by radiographic examination shall be selected for sectioning at the following rate. From every group of 700 consecutively produced ogives or portion thereof one If the sample fails, the requirement of 3.4.4, then all ogives in that group which show

46、any indication of base separation by radiographic examination shall be rejected . 0 selectioning sample shall be selected. If radiographic examination of an entire group reveals no ogives with base separation, a sectioning sample shall be randomly selected. If the randomly selected sample fails to m

47、eet the requirement of 3.4.4, the entire group of ogives represented by that sample shall be rejected. The sectioning samples shall be tested in accordance with 4.5.3. 4.4.3.1.1.2 Radioqraphic standard for base separation. A radiographic standard for base separation shall be developed by the contrac

48、tor and approved by AMSMC-QAR-Q(D) prior to its use as a standard for acceptance. The standard shall utilize the bottom end of the ogive, cut approximately 1.25 inches above the ogive shoulder. A removable plug of epoxy shall be cast in the cut-off ogive. Radiographs at simulated base separations of .010, .O15 and .O20 inch shall be taken in order to brakcet the simulated 15 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-p-64005 13 797970b 0352840 0 MIL-P-64005 (AR) base separation of . 015 inch for sensitivity.
