(clay is a recommended material) will be contoured to the back MBP. 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 MBP strike face pointing down, drop the weighted fixture two (2) times. Impacts will occur as near as possible to the center of the MBP strike face (not an edge). A radiographic image of the MBP will be inspected to identify any cracks, delamination or indentations on the MBP 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 MBP specimen as identified by the x-ray image no closer than 2.0 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). The second test shot will be located 2.0 inches from any edge and 5.0 to 6.0 inches from the first impact.

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

80 degrees Fahrenheit. Contaminate MBP in one of the following containers of fluid. At least one MBP 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 MBP 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 MBP. For salt-water contamination test, submerse the MBP in a container for two (2) hours (+15 min). MBPs shall be held vertically to drip dry for 5 minutes. Pre-conditioning and post-conditioning digital x-rays shall be taken of the MBP 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 MBP 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 MBP 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 MBP (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 the 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 MBP 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 MBP 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 MBP test specimen will be attached and centered on 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.

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 MBP 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 MBP. This buildup will use additional clay backing material conditioned in the same manner as the clay material fixture. The MBP 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

MBP test sample shall be secured 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.

4.9.11 Worksmanship and Areal Density. Dry Lay ups for each design will be examined prior to production of any test plates or production plates to visually ensure the plates exhibit uniform areal density (no unnecessary overlap/underlay, uniform material lengths and thicknesses, etc). Radiographic images (x-rays) of complete end items will be taken digitally or by the use of x-ray film. Radiography shall include the entire strike face area of the plate with the radiograph taken from a frontal or rear view. The complete MBP shall pass the requirements specified in Table IV. The Government reserves the right to change the shot pattern to target any and all anomalies, defective conditions or contaminants highlighted in x-ray. If a failure is observed when tested in accordance with sections 4.7, 4.8, and 4.9 the items shall be rejected regardless of requirements specified in Table IV. Visual end item inspection shall take place to ensure the entire plate is covered completely with no rips, tears, cuts, blistering or separation between the materials.

6.3 Ballistic testing definitions. MIL-STD-3027 shall be used for threat data and 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.

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.

Fair Impact. A projectile that impacts the armor within the specified velocity and yaw shot spacing requirements, 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.

Crown. Location of the intersection of three different curvatures vicinity the center of the upper third of the plate.

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. Fragmentation of the bullet or target material which is projected from the impact surface or rear surface of the target.

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.
