1/ The occurrence of one or more critical detectives attributable to the cartridge during any test, including warm and foul firings of cartridges from the test lot, shall result in rejection of the lot.

2/ For definition of characteristics see 6.2 and MIL-STD-636, shotshell cartridges section, for firing defect standards.

3/ If it is determined that it is necessary to fire a second function and casualty sample, the cumulative defect accept/reject criteria shall apply.

a. For individual minor defects, if the number of defects exceeds the accept criteria but not the reject criteria, the Function and Casualty test shall be performed again with a double-size sample.

b. For the cumulative of all individual minor defects, if the number of defects exceeds the accept criteria but not the reject criteria, the Function and Casualty test shall be performed again with a double-size sample.

c. For defects M107, M108, M109 and M110, if the number of failures exceeds the acceptance number but not the rejection number, the Function and Casualty test shall be performed again with a double-size sample. For the retest, the acceptance criteria for each of these defects shall be accept on 1, reject on 2 cumulative (ie including defects from the first ballistic sample.

4/ Each cartridge that misfires shall be disassembled and examined to determine the cause of the misfire.

a. If the misfire is attributed to a defective cartridge (for other than a critical defect) due to improper assembly, missing components, insensitivity, etc., then the criteria for acceptance/rejection of major characteristic shall be accept on 0, reject on 2 defective. If one misfire occurs, then a second Function and Casualty sample of 720 cartridges shall be tested in accordance with Table IV and Appendix C. The occurrence of any additional misfires shall result in rejection of the lot (accept on 1, reject on 2 defective for the cumulative total of all firings). Additionally, the occurrence of one or more critical defective during the firing of any test, including the second Function and Casualty sample, shall result in rejection of the lot.

b. The lot shall be rejected if the cartridge does not meet the critical requirements of paragraph 3.3.2 (presence of primer pocket vent hole) or paragraph 3.3.4 (presence of propellant charge).

5/ Gas escape around more than 50 percent of the periphery of the primer cup.

4. Quality Assurance Provisions

4.1 Responsibility For Inspection. Unless otherwise specified herein, in the contract or purchase order, the supplier is responsible for the performance of all inspection and test requirements as specified herein. Expect as otherwise specified, the supplier may utilize his own facilities or any commercial facility acceptable to the Government. The Government reserves the right to perform any of the inspections and tests set forth in this specification where such inspections and test are deemed necessary to ensure that supplies and services conform to prescribed requirements. Unless otherwise specified herein, in the contract or in the purchase order, all test and inspection equipment (including test barrels and test weapons) shall be supplied and maintained by the contractor in accordance with MIL-I-45607.

4.1.1 Responsibility for Compliance. All items shall meet all requirements of sections 3 and 5.

The inspections set forth in this specification shall become a part of the contractor's overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract.

Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective Materiel, either indicated or actual, nor does it commit the Government to accept defective Materiel.

4.1.2 Quality Assurance Terms and Definitions. Reference shall be made to ANSI/ISO/ASQC A8402-1994 for definitions of quality assurance terms.

4.1.3 Lot Formation. The cartridges shall be assembled into identifiable lots.

Lot size shall be 5,000 cartridges minimum and 500,000 cartridges maximum. Each lot shall be assigned a lot number in accordance with MIL-STD-1168. Only one type and weight of propellant shall be used in a lot of cartridges. Each lot shall contain no more than one lot of primers, one lot of propellant, one lot of cartridge cases and one lot of projectiles.

4.2 Inspection Provisions. Unless otherwise specified herein, the contract or purchase order, Tables II and III shall be used for nondestructive acceptance inspection. Inspection shall be by characteristic. Acceptance criteria shall be accept on zero defects and reject on one or more defects for all inspection levels. Numbers under inspection levels indicate sample size. Asterisk indicates one hundred percent inspection. If sample size exceeds lot size, perform one hundred percent inspection. One hundred percent inspection shall be used for all non-destructive critical characteristics. Unless otherwise specified, inspection level V shall be used for major characteristics and inspection level VII for minor characteristics. Section 3 and 5 requirements that are not annotated as critical or major shall be classified as minor. Unless otherwise specified, each lot of components and each lot of cartridges shall inspected in accordance with

4.3.1 through 4.3.2.4 as applicable. Classification of characteristics shall be defined in accordance with DOD-STD-2101.

The occurrence of any critical defects attributable to the cartridges (including firings of warm and foul cartridges from the test lot) shall result in rejection of the lot and no further testing shall be conducted.

3/ If the firing of a second Function and Casualty sample is required due to the occurrence of a misfire as specified by Table I, the second sample shall consist of 720 cartridges and shall be fired in accordance with the Function and Casualty test procedure.

This second sample shall be tested only for misfires and critical defects for acceptance/rejection.

4/ The test will be conducted concurrently with the bare gelatin penetration test.

5/ These tests will only be conducted during source selection and First Article Acceptance Testing.

4.3 Test Provisions. Unless otherwise specified, each lot of components and each lot of cartridges shall be tested in accordance with 4.3.1, 4.3.2, and Table IV as applicable. Unless otherwise specified, all testing shall be conducted with samples conditioned at 70° ± 5° F for a minimum of two hours. Cartridges shall be randomly selected in such a manner that the sample is representative of the lot. The cartridges shall be thoroughly mixed before being divided into sample groups for each test. If an equipment/weapon failure occurs which prevents the obtaining of a reliable test result, then the equipment/weapon shall be replaced or repaired; the individual test cartridge result shall be disregarded and another sample cartridge shall be fired for record. If the equipment/weapon failure prevented the obtaining of reliable results for the entire test series, then the entire test result shall be disregarded and a complete sample shall be fired for record. If a firing defect occurs which is not attributable to the test conditions, and which prevents obtaining a reliable result for the test, an additional cartridge shall be fired in its place; the test shall not be penalized, but the defect shall be counted in the cumulative ballistics sample for Table I.

4.3.1 Component/Subassembly tests.

4.3.1.1 Primed Case Sensitivity. The sample of 30 empty primed shotshell cartridges shall be tested for primer sensitivity in accordance with Appendix A. Twenty cartridges shall be tested at a height of 12 inches and 10 cartridges shall be tested at a height of 3 inches. If one or more cartridge primers fail at either height, the sample fails and a sensitivity rundown test shall be conducted. The sensitivity rundown test shall consist of 25 cartridges tested at each one inch increment of height between 0% and 100% firing. If the average critical height (H) plus four standard deviations (4 sigma) exceeds 14 inches, or if the average critical height (H) minus 2 standard deviations (2 sigma) is less than 1 inch, the lot of cartridges shall be rejected. The average critical height (H) is defined as the mean height at which 50% of the primers being tested will fire.

APPENDIX A

A. PRIMED CASE SENSITIVITY

A.1 Scope. The primed case sensitivity test shall be performed to determine the sensitivity limits within which the primer functions in order to provide assurance that: 1) the primer will be safe to handle, and 2) the primer will fire in the cartridges case and weapon(s) for which it is intended.

A.2 Equipment.

A.2.1 The falling mass shall be a steel ball weighing 1.94 ± 0.02 ounces with an approximate diameter of 0.938 inches.

A.2.2 The radius of the firing pin tip shall be .0500 ± .0025 inches. The firing pin shall have a nominal weight of 70 grains (0.160 ounces).

A.3 Test Procedure

A.3.1 Preparation for Test

A.3.1.1 This test shall be conducted on empty primed cases. In the event, the primed cases must be obtained by disassembly of cartridges, the disassembly shall be accomplished in such a manner as to cause the least possible distortion of the cartridge case.

A.3.1.2 The machine shall have a firing-pin protrusion of 0.058 inches minimum. This shall be measured by seating the firing pin fully against the shoulder stop in the firing-pin retainer, and measuring the resulting protrusion of the point of the firing pin from the face of the firing-pin retainer. A micrometer, dial indicator, or other suitable measuring instrument shall be used for this purpose. If the firing-pin protrusion is found to be less than the specified dimension, then the firing pin or the firing-pin retainer shall be replaced as necessary to achieve the required firing-pin protrusion.

A.3.1.3 A headspace gage having a dimension of 0.057 inches shall be placed in the case holder.

The case holder shall be lowered, if necessary, until the breech-block closes and clamps freely without interference with the headspace gage. The case holder shall then be adjusted by raising carefully until contact is felt between the head of the gage and the firing-pin retainer when the breech-block is fully closed. To verify that contact has been established between the headspace gage and the firing-pin retainer, the retainer shall be coated thinly with some colored compound (such as ''Prussian blue'' in oil) which will be transferred to the opposing surface upon contact.

The breech-block shall be closed and clamped with the headspace gage in place; the breech-block shall then be opened, and the head of the gage inspected for evidence of contact, and adjustment of the case holder refined as necessary. When the proper adjustment has been achieved, the case holder shall be locked in position by tightening the locking collar, and the adjustment shall be verified again using the colored compound and the headspace gage to assure that the adjustment has not been disturbed by tightening the locking collar. The gage shall then be removed from the case holder, and the face of the firing-pin retainer wiped clean.

A.3.1.4 A primed case shall be inserted in the case holder, and the breech block closed and clamped. The electromagnet shall be energized and the ball attached thereto. All measurements shall be made between the head of the firing pin and the bottom of the suspended ball. The method of measurement used for indicating height of drop shall be graduated in inches with an accuracy of ±1/64 inch. The position of the magnet and ball shall be adjusted so that the height of drop desired can be accomplished. When this adjustment has been completed, the ball shall be removed from the machine.

A.3.1.5 It is suggested that a plumb bob be attached to the magnet and the machine adjusted so that the point of the plumb bob is above the center of the firing pin. The plumb bob shall be removed when this adjustment has been completed. To determine if the drop ball is obtaining central impacts on the firing pin, a small piece of carbon paper may be placed on the head of the firing pin and the ball dropped from various heights. After the ball is dropped each time, the firing pin head shall be inspected to ascertain if the mark left by the carbon paper is in the center of the head. If the ball is not hitting in the center or the head, the cause thereof shall be determined and corrective action taken.

A.5.1.1 Preparation for test shall be as prescribed in A.3.1.

A.5.2 Conducting the test

A.5.2.1 Current is applied to the magnet coil of the drop test machine and the magnet height it set so that distance between bottom of suspended ball and the head of the firing pin, with primed case in position is eight (8) inches.

A.5.2.2 The procedure prescribed in A.4.2.3 through A.4.2.11 shall be repeated until the specified number of primed cases have been tested at eight (8) inches. The number of primers firing and the number misfiring shall be recorded.

A.5.2.3 The procedure prescribed in A.4.2.3 and A.4.2.11 is then repeated at nine (9) inches, ten

(10) inches, etc., until a height is reached at which all the primers in the sample fire. The magnet is then lowered to a height of drop of seven (7) inches, then six (6) inches, etc., until-a height is reached at which all the primers in the sample misfire. The number firing and the number misfiring at each height, shall be recorded.

A.5.2.4 The prescribed procedure constitutes a complete run-down test.

A.5.3 Calculation of Sensitivity Characteristics

The primer sensitivity characteristics to be calculated are "Hbar", "σ' and "a3" These three statistics can be defined in terms of the data obtained in the drop test as follows:

a. Hbar = Σ pi + (H100% + .5)

b. )p(-)kxp(= 2 iii ΣΣσ .

c.

σ 3 iii iii pkp3-)p2(+sp=a

ΣΣΣΣ

Where

Hbar Mean critical height, or the height at which 50 percent of the primers fire and 50 percent of the primers misfire.

Σ Sum of individual values pi Decimal fraction of primers misfiring at each individual height H100% First height at which all primers in sample misfire σ Standard deviation of the critical heights ki Variance factor si Skewness factor a3 Skewness value

A.5.3.1 The data obtained in the run down tests are tabulated in the manner illustrated on Figure 1.

a. In Column I "Height of Drop", enter all the intermediate heights of drop, in consecutive order; starting with the lowest height at which some of the primers fire and some fail to fire. The height at which all the primers fire and the height at which all the primers misfire are not included.

b. In Column II ''Number Fired'', enter the number of primers firing at each height.

c. In Column III "Number Misfired", enter the number of primers which fail to fire at each height.

d. In Column IV ''Fraction Misfired'', enter the decimal fraction of the primers that fail to fire at each intermediate height. This fraction is designated ''pi'', and is obtained by dividing the number of primers that fail to fire by the number of primers tested.

Results are recorded to the closest second decimal place.

e. Add numbers contained in Column IV and enter sum as Σpi. Directly under Σpi enter H100% + .5 (the first height at which all the primer in the sample misfired, plus .50). Add Σpi, and H100% + .5. The result is Hbar (mean critical height).

f. In Column V "Variance Factor'', the odd numbers in sequence ire written; i.e, 1, 3, 5, 7, 9 etc. Number 1 must be in alignment with the first entry in Column IV.

g. Column VI, the value of the individual entries In Column IV, "pi" are multiplied by the corresponding Individual entries in Column V, "ki" and the results ''piki" are placed in proper alignment in Column VI. For example, if the number in Column IV is .74 and the odd number aligned with it in Column V is 5, then place 3.70 (5 x .74) in Column VI on the same line as 5 and .74. Odd numbers remaining in Column V having no corresponding entries in Column IV are ignored.

h. Add the numbers contained in Column VI and enter the sum as Σpiki. Directly under Σpiki enter (Σpi)2, the square of the sum of Column IV. Write (Σpi)2 to the nearest second decimal place. Subtract (Σpi)2 from Σpiki. The result is σ2. Extract the square root of σ2. to obtain σ, the standard deviation.
