The inspection equipment required ko perform the examinations and tests prescribed herein is described in the “Paragraph Reference/Inspection Method“ column in the tables starting with
10、4.4.2.1. The contractor shall submit for approval inspection equipment designs in accordance with the terms of the contract. See MIL-A-48078. 4.5 Methods of inspection. 4.5.1 Dimensional control of stamped parts. In place of the normal sampling associated with the Classification of Defects, and with
11、 the approval of the Contracting Officer, a sample of at least ten (10) parts shall be dimensionally inspected to qualify the tool used in the stamping process for use in production. In addition, a random sample of five (5) parts shall be selected from the last portion of each hours production for d
12、imensional inspection as a control of the tool during production, If any defective parts are found during qualification of the tool, the tool producing the defective Sart shall not be used in production . If any defective parts are found when inspection is performed for control of the tool, the tool
13、 producing the defective part shall be removed from production. Further, that portion of production since the last tool control check shall be returned to the contractor for corrective action. All tools removed from production because of some fault, may, after reworking, be returned to production pr
14、oviding they pass the qualification test above. The contractor may request a change of inspection frequency providing he presents objective evidence to the Contracting Officer to substantiate the request . 4.5.2 Moisture and volatiles content of explosive charge. The contractor shall provide adequat
15、e controls to insure compliance with the applicable requirements. The mositure and volatiles content of the explosive charge shall be determined at the loading station at the time of loading. This determination - shall be made at least once each four (4) hours of production. Sampling and testing of
16、the explosive charge shall be in accordance with MIL-STD-650, Method 101.5. In addition, if the moisture and volatiles content fails to comply with the requirement specified on the applicable drawing and loading has not begun, the explosive charge material shall be rejected until corrective action h
17、as been taken as verified by repeating the moisture and volatiles content determination. If loading has begun, acceptor lead assemblies loaded with the non-conforming explosive charge shall be rejected. 15 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-

A minimum of two (2) assemblies, representative of the acceptor lead assemblies being processed, shall be loaded and the densities determined to qualify each press prior to its use in production, In additio
19、n, a sample of two (2) assemblies shall be processed during the last portion of each one (i) hours production from each press and the density determined as a control of each press during production. If any defective assembly is found when inspection is performed for control of a press, the press pro
20、ducing the defective assembly shall be removed from production. Further, that portion of production since the last control check shall be returned to the contractor for corrective action. All presses removed from production because of some fault, may, after corrective action, be returned to producti
21、on providing they pass the qualification test above. The following procedure shall be used to determine the density of the explosive charge. a. Weight empty acceptor lead (grams). b. Measure bottom thickness (inches). c. Measure wall thickness (inches). d. Load cup. e. Weight loaded acceptor lead (g
22、rams). f . Measure height to top of charge (inches). g. Measure outside diameter of loaded acceptor lead h. Calculate weight of charge (e-a) (grams). i. Calculate height of charge (f-b) (inches). j. Calculate volume of explosive charge (cubic (inches). centimeters) = (.7854) x (16.39) x (g-2c) x (g-
23、2c) x (i). k. Calculate density of explosive charge (above). (grams per cubic centimeter) = (h/j). -. If any assembly fails to comply with the density requirements specified on the applicable drawing, it shall be classed defective. This is a destructive test. Assemblies so tested shall not be return
24、ed to the lot. 16 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- MIL-M-70778 13 = 777770b 0357448 3 a MIL-M-70778 (AR) NOTE: When weighing in water, use distilled water containing a suitable wetting agent, e .g. “Aerosol“ (lcc per 250cc distilled w

The acceptor lead assemblies shall be assembled into a plastic holder and placed with the end of the assembly in contact with a witness plate of material and thickness as specified in 3.3. The acceptor lead assembly shall be initiated by an M100 electric detonator.
26、The detonator shall be initiated by applying the energy from a suitable power source (e.9. 100 microfarad capacitor charged to 1.6 volts maximum or 6 volt battery). The depth of the desression in the witness plate shall be determined using a dial indicator with a .O15 + .O01 inch spherical radius in
27、dicator tip. - 4. 5. 5 Conditioning and functioning. 4.5.5.1 Preparation of samsles. Each acceptor lead assembly to be subjected to the functioning test shall be assembled into a slider assembly as per 9366684. This assembly shall then be assembled into a SfA as per 9366668. The slider shall be asse
28、mbled as to be “in line“ with the centerline of detonator hole of housing to be off .O45 - .O05 inch from centerline of acceptor lead of slider. Assembly of the piston actuator and the safety pin shall be omitted. An electric detonator M100 (Dwg. 9245691) shall be shorted and assembled with seal was
29、her into the input hole of the SstA assembly-. A successful test shall constitute test shall consist of firing the detonator propagation thru the acceptor lead assembly igniting the transfer lead assembly and into the lead cup assembly. A similar test plan could be formulated by the contractor provi
30、ding that acceptance of the test method is approved prior to testing by the government agency. 4.5, 5. 2 Hot conditioninq. The acceptor lead assemblies to be conditioned and functioned at hot temperature shall be prepared as specified in 4.5.5.1. They shall then be placed in a suitable temperature c
31、onditioning box and the temperature increased to 165 + 50F with relative humidity not less than 15%. The rate of temperature increase shall not exceed 180F per minute. The samples shall be maintained at temperature for iortj! (40) hours minimum. The temperature in the oven shall then be reduced to 1
