17、on elements shall be manufactured in accordance with the drawings listed on DL613460, andshall be from lots which were accepted in accordance with the requirements of MIL- 1-81537. When the same contractor manufactures the Mark 13 Mod O ignition element and the Mark 67 Mod O impulse cartridge and as

18、sembles the ignition element in the cartridge, the testing requirements of MIL-1-81537 for the ignition element shall be waived (see 4.6.1). The ignition element shall be free of the following defects when X-rayed (see 4.6.6.2): missing, defective or improperly assembled components; charges missing

19、or abnormally small; or any other imperfections which could adversely affect performance. 3.6 Propellant charge. 3.6.1 Quantity. All propellant charges shall be as specified on Drawing 2519598.

The handling and loading of smokeless powder exposed to the atmosphere shall be performed only under conditions that do not permit the relative humidity to exceed 75 percent. 3.6.3 Smoke

21、less powder, condition. The smokeless powder used shall exhibit no evidence of decomposi- tion (see 4.6.2) 3.7 Cartridge inspection. 3.7.1 Bridge circuit resistance. The resistance of the bridge circuit in each completely assembled cartridge, when measured electrically (see 4.6.4), shall be not less

22、 than 0.08 ohm nor greater than 0.15 ohm. 3.7.2 Leakage. Cartridge leakage rate shall be not greater than 10-5 cubic centimeters of air per second (see 4.6.5). 3.7.3 X-ray.

Unless otherwise specified in the contract or purchase order, the con- tractor is respnsible for the performance o

28、f aii inspection requirements as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Govern- ment. The Governm

29、ent reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items must meet all requirements of sections 3 and 5. The i

30、n- spection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the con- tractor of the responsibility of assuring that all products or supplies submitte

31、d to the Government for ac- ceptance comply with all requirements of the contract. Sampling in quality conformance does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.2 Classification of inspe

32、ctions. The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conformance inspection ,(see 4.5). 4.3 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed as specified in the applicable test

33、method of 4.6. 4.4 First article inspection. First article inspection shall be performed after award of contract and prior to production by a facility designated in the contract or order (see 6.2). A first article sample acceptable for environmental and function testing shall be considered as a samp

34、le which has met the requirements of 3.2 through 3.7.3 and 3.10 of this specification. First article inspection shall be performed on sample units which have been produced using the same materials, equipment, processes and procedures as will be used in regular production. All parts and materials, in

35、cluding packaging and packing shall be the same as used for regular production and shall be from the intended sources of supply. 4.4.1 Sample size. The first article sample shall consist of 106 cartridges. 4.4.2 Inspection routine. Ninety-six cartridges shall be expended in the tests listed below an

36、d 10 shall be retained for investigative purposes. Testing shall consist of the following tests as prescribed in MIL-D-21625 (see 6.2): temperature and humidity cycling (18); 15 “g“ shock (12); vibration (12); salt spray (12). The number in parentheses denotes the number of cartridges allocated for

37、each test. These cartridges (with the exception of classified on the drawing of DL2519598. i TABLE I. Quality conformance tests and examinations.

Unless otherwise speci

39、fied (see 6.2), the production lot size shall be not less than 301 and not greater than 800. Only primary components from a single lot shall be used in a production lot of car- tridges; however, one primary component production lot may be used in more than one cartridge produc- I. - tion lot. 4.5.2

Verification. shall be made available that the ignition ele

43、ments used were certified and accepted in accordance with the requirements of 3.5. 4.6.2 Smokeless powder, condition. Smokeless powder shall be inspected in accordance with the applicable 4.6.3 Visual examination. All cartddges shall be visuallyexamined. Cartridges having any of the defects of 3.8 s

44、hall be cause for rejection. The preservation-packaging, packing, and marking of the cartridges shall be examined for conformance to section 5. paragraphs of OP 5. Evidence of decomposition shall be cause for rejection. 4.6.4 Bridge circuit resistance. Conformance with the bridge circuit resistance

45、of 3.7.1 shall be ascer- tained on all completely assembled cartridges by means of a test circuit which limits the bridge circuit cur- rent to not greater than 25 milliamperes. The test circuit shall be connected to the cartridge through a fully assembled electrical connector, MS3106-12-58. A nw con

46、nector shall be used after not more than 500 con- nections. A safety chamber with an interlock switch shall be used to protect the operator during the applica- tion of current. A suitable instrument which is known to be accurate to within 1 percent in the range of resistance specified shall be used

47、to determine whether or not the requirement is being met. Units which fail to meet the requirements of 3.7.1 or fail to assemble completely, by hand, with the specified connector shall be cause for rejection. The results of bridge circuit resistance measurements shall not be affected by resistance o

48、f the test circuit and connector. 4.6.5 Leakage. Each cartridge in the first article or production sample shall be leak tested in a dry gas leak tester. Cartridges which exhibit a leak rate greater than cc per second of air at a pressure dif- ferential of 1 & 0.1 atmosphere shall be considered defec

49、tive. Cartridges of the first article sample which exhibit a leakage defect shall be cause for rejection. If the number of cartridges of the production lot sam- ple exhibiting leak defects exceeds an AQL of 2.5 percent defective from table II of MIL-STD-105, then a 100 percent leak test of the lot being tested shall be required. Cartridges which exhibit a leak rate greater than that specified above shall be cause for rejection (see 6.5). 4.6.6 Radiographic examination. 4.6.6.1 Cartridge. All cartri
