QUALITY ASSURANC
14、E PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the con- tract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified, the supplier may utilize his own facilities or any commer
15、cial laboratory acceptable to the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed nec- essary to assure that supplies and services conform to prescribed requirements. as follows: 4.2 Classification of in
16、spection. Inspection of the lead shall be classified a. Preproduction inspection (See 4.5.) b, Quality conformance inspection (See 4.6. ) 4.3 Sampling. (See 6.2.1. ) 4.3.1 Lot size. The term “lotff shall mean “inspection lot“, that is a collection of product submitted by a supplier for inspection. U
17、nless otherwise specified in the contract or order, the number of product in each lot shall be ten thousand (10,000). 4.3.2 Premoduction samole, A preproduction sample of fifty (50) leads, manufactured in accordance with 3.2, shall be subjected to the quality confor- mance inspections detailed in 4.
18、6. Acceptance of the preproduction sample shall be judged in accordance with MIL-STD-l05D, inspection Level II, with an AQL of 1. O. A dud (see 6.3.1) shall be cause for rejection of the preproduction sample. Further production of the primers by the supplier, prior to approval of the preproduction s
19、ample, shall be at the suppliers risk. /- 3- Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Provided by IHSNot for ResaleNo reproduction or networking

The lead shall be detonated by Detonator Mk 59 Mod O, which in turn shall be initiated by either Electric Primer Mk 137 or other suitable initiator with equal output. The desig
23、n of the test holder shown in Figure 1 may be modified to ac- commodate a suitable primer used for reliable initiation of the detonator. 4.6.1.1 Lead output and functioning. This test shall be conducted using the 4.6.1.1.1 Measurement procedure. The maximum depth of indentation produced in each test
24、 block shall be measured and recorded to the nearest O. O01 inch, using the dial indicator specified in 4.4. lb. The dial indicator shall be mounted over a horizontal surface plate so that the indicator stem is perpendicular to the surface plate, as shown in Figure 2. The test block shall be placed,
25、 in- dented side up, in a holder so that the bottom face of the test block is approxi- mately parallel to the surface plate. The indicator tip shall be lowered to the bottom of the indentation, and the indicator dial set to zero, The test block holder shall then be moved so that the indicator tip co
26、ntacts the surface of the testblock approximately 1/8 inch from the periphery of the test block. The indicator reading shall be recorded to the nearest O. O01 inch, Four readings shall be taken at approximately equidistant points near the periphery of the in- dentation. The arithmetic average of the
27、 four readings shall be taken as the average depth of indentation for each test block. The average depth of indenta- tion shall be not less than O. O10 inch. 4.6.1.2 Visual examination, Visual examination shall be made on each Nonconfor- lead submitted for delivery to the procuring agency. The lead
28、shall be examined for conformance to the requirements of good workmanship in 3.4 mance is cause for rejection of individual unit.

31、ermediate packages, and shipping containers shall be marked in accordance with the requirements of MIL-STD-129, 49 CFR Part 71 to 78, and LD 275960. 5.4 Lead data cards. Five (5) cards, 3 inches by 5 inches, made from commercial white cardboard, printed as shown in Figure 3, shall be filled out for
32、eachlot of leads, and shall be distributed as follows: a. Two cards shall accompany the shipping ticket. b. Two cards shall be forwarded to the procuring activity. c. One card shall be placed in each packing container. 6. NOTES 6.1 Intended use and description. -6.1.1 Intended use. The lead is inten
33、ded for use in the motor separation and airframe separation explosive blocks of a rocket-propelled missile. 6.1.2 Description, The lead is designed to be reliably initiated by Deton- ator Mk 59 Mod O and to yield a highly brisant output. The lead is approximately O. 161 inch in diameter by O. 380 in

For the purpose of this specification the following defini- tion
38、has been established. 6.3.1 Dud. Any lead that fails to explode when subjected to the output of an adjacent Detonator Mk 59 Mod O, shall be termed a dud. Failure of any lead to explode due to faulty detonator functioning or test equipment shall not be con- strued as a dud. 6.4 Preparation for delive
39、ry criteria, Criteria for use of the proper level of packaging, packing, and marking shall be as specified in Section 5. 6.5 Safety precautions. 6.5.1 Special handling instructions. 6.5.1.1 Extreme care and precautions shall be exercised at all times in the handling and loading of the RDX material.
40、6.5.1.2 No more than 2 grams of RDX shall be present at each loading station and only when an operator is present. 6.5.2 General safety precautions. The loading assembly, and handling of explosivs, ammunition, ammunition components, fuzes, detonators, primers, tracers, boosters, pyrotechnics, etc.,
41、and subassemblies thereof , involve hazar- dous operations, and therefore require suitable explosives safety precautions Use of this specification shall not be construed as to relieve the contractor or manufacturer of responsibility for the safety of his operations. The following paragraphs list the
42、 minimum provisions that a contractor or manufacturer (loader) of these items should observe in order to fulfill his responsibility for safety. At Naval Ordnance Systems Command and other 3overnment plants, these provisions are mandatory. Such other warnings and precautions pertinent to the operatio
43、nal effectiveness or safety during use or loading of the specified item, are included in the detail provisions of the specification. 6.5.2.1 All loading operations should be conducted in a neat and orderly manner. 6.5.2.2 Safe equipment and methods should be utilized for transporting and handling ex
44、plosives and loaded parts. Where required, remote control barricaded handling equipment shall be used for explosive operations, such as mixing, pouring,. weighing, charging, sifting, drying, pressing, casting, and crimping.

45、 license from IHS-,-,-MIL-L-82531 (OS) 6.5.2.3 Personnel handling detonators, primers, delay elements, leadins, boosters, and related parta that affect functioning, should, insofar as practicable, avoid using bare fingers or improper equipment to prevent damage, corrosion, or deterioration from pers
46、piration or other contaminating deposits. 6.5.2.4 The exposure of explosive materials and related parts should be so controlled as to minimize the absorption of moisture from the atmosphere or other sources during loading and handling operations. 6.5.2.5 All explosives and completely or partially lo
47、aded items should be stored in suitable storage magazines located in accordance with the American Table of Distances (ATD) or other applicable safety standards; and, while in process, kept in safety lockers and chests if in loading rooms, or in adequate ready or service magazines located in accordan
48、ce with intra-plant distances when outside of loading rooms. For Navy explosive loading plants,. the pro- visions of the Armed Services Explosives Safety Board covering quantity-distance relations for explosives, shall apply. 6.5.2.6 Proper care should be exercised at all times to protect personnel
49、from accidents, fires, or explosions, and to limit damage to equipment and loading areas. in this connection, the following precautionary measures should be observed. 6.5.2.6.
