4.3 Order of Testing. Performing the various testing (operating, ownership & support, operating environment, and performance) can occur in any order.

4.4 Verification Methods. The types of verification methods included in this section are visual inspection, dimensional measurements, sample tests, component properties analysis and similarity to previously approved or previously qualified designs.

4.4.1 Verification Using Standard Samples. Use standard samples to verify colors with visual inspections.

4.5 Responsibility for Compliance. Production items shall meet all requirements specified in section 3. The supplier shall establish and maintain documented procedures for inspection and testing activities in order to verify that the specified requirements for the product are met. The required inspection, testing and the records to be established shall be detailed in a quality plan available to the government as specified in the contract or procuring activity. The inspection set forth in this specification shall become part of the contractor’s overall inspection procedures or quality system. 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 the manufacturing operations is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material.

4.6 Operating Requirements. Complete each test in this paragraph.

4.6.1 Insertion. One barehanded person shall demonstrate insertion of the NBBP into the

LBT-2564 front or back pocket and side pockets without tools or special aids. Perform insertion into Government furnished carrier in a maximum of 60 seconds.

The Contractor shall provide Material Safety Data Sheets (MSDS) to the Government for all materials comprising the end item.

4.6.7.3 Magnetic Influence. The NBBP shall be tested for magnetic influence using magnetic and lensatic compasses. The NBBP shall not cause any deviation of the compass needle.

4.7 Ownership and Support Requirements. Perform the verification in this paragraph.

4.7.1 Durability. Demonstrate durability by performing drop test analysis. Attach NBBP, belt or other non-obstructive retaining device to the front surface of a 10.0 ± 0.1 lb. weighted object. The weight of the moment arm and straps shall be 8.5 lbs ± 0.5 lbs. The weighted object (clay is a recommended material) will be contoured to the back NBBP. A fixture similar to that in Figure 1 has shown to provide accurate and reproducible results and should be securely mounted to the floor. The drop height shall be 48.0±0.5 inches. (90 degrees from horizontal) (approx. 16 ft/sec) from the flat hardened surface (stiffness of at least 3 x 106 psi and a mass much greater than the moving components (e.g. concrete slab)) and with the NBBP strike face pointing down, drop the weighted fixture two (2) times. Impacts will occur as near as possible to the center of the NBBP strike face (not an edge). A radiographic image of the NBBP will be inspected to identify any cracks, delaminations or indentations on the NBBP surface. Perform ballistic testing in accordance with paragraph 3.9.3. The first test shot will be taken at the most severely damaged area of the NBBP specimen as identified by the x-ray image no closer than 1.5 inches from any edge. If no damage is visible the first shot will be taken vicinity of the impact location (center of the strike face).

4.8.2 Fluid Resistance. Conduct this test at fluid and ambient temperatures between 60 -

80 degrees Fahrenheit. Contaminate NBBP in one of the following containers of fluid. At least one NBBP will be subjected to contamination to each of the three fluids; 30 weight lubricating oil of commercial grade SE or better, commercial grade JP-8 and salt water. For lubricating oil and JP-8, place the NBBP strike face down in a pan filled with 0.50-inch of fluid for two (2) hours (+15 min) with a twenty (20) pound weighted object on top of the NBBP. For salt-water contamination test, submerse the NBBP in a container for two (2) hours (+15 min). NBBPs shall be held vertically to drip dry for 5 minutes. Pre-conditioning and post-conditioning digital x-rays shall be taken of the NBBP samples. The test specimen shall be ballistically tested in accordance with paragraph 3.9.3 within 60 minutes after each exposure.

4.8.3 Buoyant Test. Fill a 28x18x10 inch tub with distilled water at room temperature.

Let the plate stay in the water, strike face down, inhibited by wave motion or test instrumentation. Observe the plate after two hours. Plate shall have any or all parts of its surface above the water. No ballistic tests are required.

4.8.4 Fungus Test. Verification of compliance with the fungus requirement will be performed through the use of certified materials and coupon sampling. A fungus test may be performed on all non-certified materials at the discretion of the government. The results of those tests will be for government reference but the government reserves the right to fail the NBBP design due to excessive fungus growth. Tests will be performed in accordance with Method

508.6 of MIL-STD-810G. A sample of each non-certified material will be placed in the fungus test chamber for 28 days. No ballistic tests are required. The amount of fungus growth should support a grade of 2.5 or less, as specified in MIL-STD-810G.

4.9 Performance Requirements. Complete each test in this paragraph.

4.9.1 Ballistic Test Criteria. For all V50 BL and V0 acceptance tests the following minimum information is required by the government to validate performance:

1. Armor description including Design code, size, dimensions, thickness, weights of all components of the NBBP system.

2. Test projectile threat code, weight and reference weight.

3. Temperature and humidity measurements.

4. Yaw angle.

5. Angles of target obliquity.

6. All velocity measurements of each test shot used to test the NBBP (regardless of whether that particular velocity was used in the V50 or V0 determination). Ensure proper drag table for each threat is used to calculate impact velocity.

7. PP (Partial Penetration; with shoot pack ply count as applicable) and CP (Complete Penetration) next to each shot velocity as determined.

8. Back Face Deformation measurements in mm with significant digits recorded only to the accuracy of the measuring device.

9. Spall/debris ejection count (when required).

10. Name of organization/company performing tests.

11. Type of gun barrel, caliber, propellant type, propellant weight, twist rate, and gun barrel serial number.

12. Calculated V50 BL. In a situation where the V50 BL or V0 data sheet would compromise the Security Classified Guide for Armor Materials, the data sheet should exclude the specific projectile used during testing.

13. Clay type, drop temperatures, locations, depth, and clay box number.

14. Remarks or Notes for all testing anomalies, unfair hits, etc.

15. All shot locations.

16. Revision #/level of all ballistic test software used by test lab (i.e. FARO software including smoothing function, drag calculation software, etc)

17. Time and date of clay calibration drops and ballistic shots.

18. Photos of clay calibration drop locations, ballistic impact locations on the plate, and any anomalies.

4.9.2 Projectile Velocity Determination. Projectile velocity measurements methods that utilize either contact screens or radar will be used. Contact screen methods that employ either high velocity lumiline screens or electrical contact screens activated by a passing projectile opening or closing a circuit are preferred. An electric counter type chronograph calibrated to microseconds, will also be used in conjunction with the contact screen method. Doppler radar capable of accurately measuring the projectile striking and residual velocities can also be used.

Personnel conducting ballistic testing should be properly trained in velocity measurement determination using the Doppler radar equipment. Radiographic equipment calibrated to capture the projectile at calibrated time intervals of flight may also be used.

4.9.3 Weapon Mounting Configuration. The spacing from the weapon muzzle to the first pair of triggering devices shall be sufficient to prevent damage from muzzle blast and obstruction from smoke in case optical devices are used. Recommended distances can be found in USATECOM TOP 4-2-805. Spacing between triggering devices is a function of the expected velocity of the projectile being fired. In many instances, physical restriction, such as short overall distance from muzzle to test sample dictates the spacing of the triggering devices. The last pair of triggering devices shall be placed at least four (4) ft (122 cm) in front of the test sample and should be protected from possible damage resulting from fragments.

4.9.4 Environmental Test Conditions. All ballistic tests shall be performed in a standard atmosphere of 68 + 10 degree Fahrenheit and 50 + 20% relatively humidity. Temperature and humidity measurements shall be recorded before the beginning of days test firings and a minimum of every two hours thereafter.

4.9.5 Projectile Yaw. Projectile yaw shall be measured for each firing by yaw cards, flash x-ray or photography. Any round for which yaw is determined to be greater than 3.0 degrees shall be disregarded in the calculation of the ballistic limit. The measurement system employed should be capable of measuring yaw within an accuracy of 1.0 degree.

4.9.6 V50 BL. See Appendix A.

4.9.7 PP and CP for V50. Complete and partial penetrations will be determined based on the definitions provided in paragraph 6.3.

4.9.8 V50 Test Sample Mounting. Unless otherwise stated the following conditions shall be performed during V50 testing. The NBBP shall be secured to the clay-mounting block with the impact side perpendicular to the line-of-flight of the projectile. Testing will be performed in accordance with MIL-STD-662F except partial and complete penetrations will be determined based on definitions provided in paragraph 6.3.

4.9.9 Ballistic V0 Testing. Ballistic V0 testing of NBBP shall be conducted on a recurring basis per paragraph 3.9.3 and procedures specified in the contract (see paragraph 6.2).

4.9.9.1 V0 Determination for Acceptance. For V0, the minimum velocities as stated in

Appendix A will be the requirement.

4.9.9.2 Impact Location. See Appendix A.

4.9.9.3 Back Face Deformation (BFD) Measurement.

The back of the NBBP test specimen will be attached and centered on to OleTex CEJN

200 foam pad and then to a block of non-hardening, oil-based modeling clay so that no movement of the test samples occurs before, during or after the ballistic event. The clay material fixture shall be in the form of a single block at least 5.5 inches thick and 24 x 24 inches in length and height with 0.75 inch plywood backing. For the front/back plate, the foam pad shall measure 11inches by 13inches by 1inch; for the side plates the foam pad shall measure 6inches by 8inches by .5 inch. The clay shall be conditioned for at least 3.0 hours and worked thoroughly to remove any voids. A new clay conditioned block shall be used for each NBBP sample. The clays consistency shall be such that depression of 25 ± 3mm in depth is obtained when a 1 kg ± 10 gm

(2.2 lb ± 0.35 oz) cylindrical steel mass, 44.5 ± 0.5 mm (1.75 ± 0.02 in) in diameter and having a hemispherical striking end, is dropped from a height of 2 m ± 2 cm (6.56 ft + 0.8-in) onto one of its square faces. During the three drop tests for each block, the center of each impact location shall be at least 4.0 inches from any previous impact site and from any edge of the clay block. A guide tube or other means may be used as required to assure that the striking end of the cylindrical mass impacts the backing material squarely at the desired location. Depressions and BFDs will be measured with instruments capable of ± 0.4mm accuracy. The calibration drop indentations will be filled with temperature conditioned clay prior to conduct of the V0 test shots. The clay boxes will be numbered so as to be recognized by an overhead camera. Any portion of the clay “chest mold” will not be adhered to any portion of the clay block that has last been smoothed or worked with a “putty knife” or “flexible blade.”

Before ballistic testing the clay material will be contoured to the back face curvature provided by the NBBP backed by OleTex CEJN 200 foam pad. This buildup will use additional clay backing material conditioned in the same manner as the clay material fixture. Both the shoot pack and NBBP will be strapped or taped to the curved surface of the clay material. Back face deformations in the clay will not exceed 44.0 mm max, without incurring a minor defect when measured from the original undisturbed surface of the clay backing material to the post-impact surface with the reference direction perpendicular to the front surface (facing the line-of-fire) of the box. All BFD measurements will be conducted at 0 degree obliquity only. Indentation measurements will utilize laser scanner measurement instruments, which provide a means to accurately establish the difference between the original undisturbed clay surface and the post-impact surface. The BFD measurement is the maximum-distance-length, which is the length of the longest line segment parallel to the reference direction between the pre-impact clay surface and the post-impact (BFD) clay surface, where the reference direction is defined to be perpendicular to the front surface (facing the line-of-fire) of the box containing the clay backing material. Deformations will be recorded in mm to the nearest tenth digit following standard ASTM E29 “Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications” (“Five-even” rule)(Rounding Method) (i.e. 44.050 = 44.0,

44.051 = 44.1 and 47.950 = 48.0).

The laser scanner measurement instruments and associated software must be approved for use by ATEC. Changes to this software will be managed by a Configuration Control Board (CCB) which will certify each change. The software package must be capable of meeting the following requirements:

-Uniform sample: 0.5mm -Wrap with Auto Noise Reduction -Clean function w/ smooth option -Fill holes (curvature based hole filling) -Remove intersecting triangles -Remove spikes at 10% -3D Compare to find deepest point The software package must be able to remove and fill cracks in the clay if the deepest point falls within a crack with an area < 0.7 mm x 0.7 mm.

4.9.9.4 Test Sample Mounting. The framed clay block shall be rigidly fixtured in a manner which will resist, without movement, the anticipated force of the ballistic impacts. The NBBP test sample shall be secured to OleTex CEJN 200 foam pad in the vertical position, perpendicular to the projectile line of flight. The frame supports must be capable of retaining the sample and withstanding shock resulting from ballistic impact by the threat round on the test sample. The test sample mounting shall be capable of adjustment for moving the sample in the vertical or horizontal positions so that the point of impact can be located anywhere on the sample and rotation on the vertical axis so that zero degree obliquity impacts can be achieved anywhere on the sample. Mark intended shot locations on the actual plate.

4.9.10 Blunting Gap Testing. Per Appendix A, mounting per paragraph 4.9.8.

5. PACKAGING

5.1 Packing. For acquisition purposes, the contract or order shall specify complete packaging requirements. When DOD personnel perform material packaging, those personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements.

The Inventory Control Point packaging activity within the Military Department of defense Agency, or within the Military Department’s Systems Command, maintains packaging requirements. Packaging data retrieval is available from the managing Military Department’s or defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.

6. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.).

6.1 Intended use. The NBBP is intended for use in the LBT-2564 tactical buoyancy vest by Visit Board Search and Seizure (VBSS) teams. The NBBP will provide multi hit protection against certain small arms.

6.2 Acquisition requirements. Acquisition documents should specify the following:

a) Title and date of this document.

b) When first article, and pre-production items are required.

c) Color required.

d) Size tariff.

e) Contractually approved ballistic package(s) to include package name, complete description, and FAT acceptance letter.

6.3 Ballistic testing definitions. MIL-STD-3027 shall be used as definition references only. In the case of a conflict between MIL-STD-3027 and this document, this purchase description shall take precedence. The following definitions are provided to assist in understanding the test procedures:

Over-Velocity. Striking velocity that is higher than the specified threat requirement.

Under-Velocity. Striking velocity that is lower than the specified threat requirement.

Fair Impact. Impact of an unyawed bullet of the specified bullet type, velocity and obliquity (± 3 degrees) except an impact which violates shot spacing or edge distance (see Appendix A) shall be an unfair impact.

Complete Penetration (CP) for V50 Testing. A complete penetration occurs when the impacting projectile or any fragment thereof, or any fragment of the test specimen perforates the rear surface of the NBBP.

Fair Impact. A projectile that impacts the armor at an angle of incidence no greater than + 5 degrees from the intended angle of incidence and with no greater than 5 degrees (3 degrees for rifle rounds) of yaw, will be considered a fair impact.

Partial Penetration PP(P). Any fair impact that is not a complete penetration shall be considered a partial penetration.

Complete Penetration (CP) for Acceptance Testing. A complete penetration will have occurred when the projectile, fragment of the projectile or fragment of the armor material is imbedded or passes into the clay backing material used to measure transient deformation. Paint or fibrous materials that are emitted from the back of the test specimen and rests on the outer surface of the clay impression are not considered a complete penetration. Any residue from OleTex CEJN 200 foam pad is not considered a complete penetration.

Residual Velocity. The velocity at which a projectile exits the rear surface of an armor sample.

Used only for Vs/Vr testing.

Areal Density (AD). A measure of the weight of the ballistic filler of the armor panel per unit area, usually expressed in pounds per square foot (lb/ft2) or kilograms per square meter (kg/m2) of surface area.

Obliquity. A measure, normally in degrees, of the extent to which the impact of a projectile on an armor material deviates from a line normal to the target. Thus, a projectile fired perpendicular to an armor surface at 0 degrees obliquity.

Spall. The detachment or delamination of a layer of material or the ejection of projectile/armor material in the area surrounding the location of impact, which occurs on the front of the armor surface. Spalling may be a threat mechanism even when penetration of the armor itself is not complete. Any residue from OleTex CEJN 200 foam pad is not considered spall.

Yaw. Projectile yaw is the angular deviation of the longitudinal axis of the projectile from the line of flight at a point as close to the impact point on the target as is practical to measure.

V50 Ballistic Limit (BL). In general, the velocity at which the probability of penetration of an armor material is 50 percent.

APPENDIX A

V50 Ballistic Limit Measurements

V50 ballistic limit testing of NBBPs shall be conducted as per paragraph 3.9.2 and 4.9 of this CID and procedures specified in the contract (see paragraph 6.2) and MIL-STD-662. The NBBP will yield the minimum V50 ballistic limit of 3000 fps at 0 degree obliquity with M80 7.62x51mm FMJ, steel jacked bullets.

Ballistic limit measurements will be performed on the actual NBBP (six (6) shots maximum per front/back NBBP and two (2) shots maximum per side NBBP in accordance with MIL-STD- 662F). Shot spacing should be no closer than 1.5 inches from an edge and each subsequent shot shall be spaced at least 2.0-inches from any previous shot.

V50 Calculation: The arithmetic mean of three (3) Partial Penetration (PP’s) and three (3) Complete Penetrations (CP’s) within a 125 ft/sec velocity spread or four (4) Partial Penetration (PP’s) and four (4) Complete Penetrations (CP’s) within a 150 ft/sec velocity spread yield the minimum allowable V50 BL determination that will be accepted as reliable test results.

If 6 partial penetrations occur that are above the minimum V50, the plate demonstrates a V50 above the minimum, the plate passes, and that V50 test is terminated. All shots’ velocities are recorded.

V0 Ballistic Resistance

Ballistic V0 testing of NBBP shall be conducted on a recurring basis per paragraph 3.9.3 and

4.9.9 and procedures specified in the contract (see paragraph 6.2). For V0, the minimum velocities as in Table I-A below will be the requirement. The NBBP will yield a back face deformation UTL less than 44mm with M80 7.62x51mm FMJ, steel jacked bullets at 2780 fps + 30 fps at 0 degree obliquity.

The ballistic V0 testing of front/back NBBP shall have a minimum of 6 impacts at 0 degree obliquity. Three shots will be edge shots no closer than 2 inches from any edge; and three other shots must impact 2 inches away from any other impact. Shot sequence shall be random alternating , sample shot locations per Figure 1-A. Back face deformation measurements, per paragraph 3.9.5 and 4.9.9.3, will be taken first three shots.

The ballistic V0 testing of the side NBBP shall have a minimum of 2 impacts at 0 degree obliquity. Each shot shall impact 2 inches from any edge and 2 inches from any previous impacts. Back face deformation measurements, per paragraph 3.9.5 and 4.9.9.3, will be taken for taken for first shot taken. Sample shot locations per Figure 2-A.

Blunting Gap Resistance

Blunting Gap will be conducted on 2 front/back plates with 6 shots on each plate M1943 7.62x39mm PS at the velocities stated in Table I-A. There shall be no complete penetrations. No other measurements will be taken.
