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

4.2.2 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.

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

4.2.2.3 Uniform Areal Density. Dry lay-up for each design shall be examined to visually ensure the plates exhibit uniform areal density (no overlap or underlay, uniform material lengths, and thicknesses, etc.).

4.3 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.

4.4 Workmanship 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.).

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)

CUI

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.

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

6.4 Government Loaned Property. Contact the contracting official if necessary for the loan of property required to verify conformance with paragraph 3.5.1.

APPENDIX A

IMBP Testing Protocol

V50 Ballistic Limit Measurements

V50 ballistic limit testing of IMBPs shall be conducted as per paragraph 4.8.6 of this PD and MIL-STD-662. The IMBP will yield the minimum V50 ballistic limit as outlined in Table A.1 below. Threats and supporting information are outlined in Appendix F.

Table A.1: V50 Ballistic Limit Protocol Threat Shots Per Plate

RED 3

ORANGE 3

YELLOW 3

GREEN 3

BLUE 3

Ballistic limit measurements will be performed on the actual IMBP. Shot spacing for any part of impacted round should be no closer than 0.75-inches from an edge and each subsequent shot shall be spaced 5.0-6.0 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 IMBP shall be conducted on a recurring basis per paragraph 3.8.3 and

4.8.7. Appendix B outlines IMBP V0 performance requirements.

The ballistic V0 testing of IMBP shall have a minimum of 3 impacts (2 impacts at 0-degree obliquity and 1 impact at 30-degree obliquity). The first two shots must be fired at 0-degree obliquity and the third shot at 30-degree obliquity. For the 30-degree obliquity shots, the direction of the obliquity depends on which side of the centerline is the intended impact point. If on the right, that side shall be rotated up-range (toward the gun barrel); if left, that side shall be rotated up-range. One shot shall be an edge shot (0-degree obliquity) between 0.75 and 1.25 inches from any edge (see Figure A.1); one shot shall be a crown shot (0-degree obliquity) 5.0-

6.0 inches from any other shot; the third shot (30-degree obliquity) 5.0-6.0 inches from any other shot. Back face deformation measurements, per paragraph 4.8.9, will be taken on the first two

CUI

shots, and UTL computed. Back face deformation measurements, per paragraph 4.8.9, will be taken on the last shot for government reference.

Blunting/Shatter Gap Resistance

Appendix B outlines IMBP blunting gap performance requirements.

APPENDIX B

IMBP First Article Test (FAT) Protocol

B.1. First Article Testing. This Appendix is a mandatory part of the specification and provides the detailed protocol for the execution of First Article Testing (FAT). FAT ensures that the contractor may furnish a ballistic plate that conforms to all contract requirements for acceptance.

FAT samples shall be manufactured using the same materials, equipment and procedures used during production and the FAT samples shall serve as the manufacturing standard. FAT may be waived by the Government when supplies identical or similar to those called for have previously been tested and/or delivered by the offeror or contractor and were accepted by the Government.

FAT for the IMBP shall be conducted in two (2) parts. Part 1 shall be in accordance with the DOT&E protocol and Part 2 shall consist of additional testing required to meet service-specific requirements. First Article Testing shall be conducted at Aberdeen Test Center (ATC). In order to gain FAT approval, a submitted design shall successfully pass the requirements outlined in FAT Part 1 and Part 2. V0 and blunting/shatter gap testing will be conducted with NIJ Type IIIA/HG2 shootpacks. Failure to meet the requirements of any sub‐test or part thereof shall result in rejection of the First Article Test. Table B.1 outlines IMBP FAT protocol. Table B.2 outlines shot order and location for V0 and shatter gap testing. Threats and supporting information are outlined in Appendix F.

Note: Shot tolerance disputes shall be addressed by the vendor’s representative at the time of shot in question. The government will not accept shot disputes after test results have already been released.

B.2 Requirements – FAT Part 1. Table B.3 represents the resistance to penetration and BFD statistical analysis required for both torso and side plates for FAT Part 1 testing. For resistance to penetration, the LCL for the P(nP) is the statistic of interest and the result compared against a 90% P(nP) for first shot (Torso and Side Plates) and 70% P(nP) for the second shot (Torso Plates Only). For BFD, the UTL shall be computed using BFD as a continuous normal random variable and the result compared against the requirement.

B.2.1 Resistance to Penetration. For each valid test shot, the result is determined to either experience a system complete penetration or a system partial penetration as defined in section 6.

The numbers of system complete and system partial penetrations shall be used to calculate the P(nP) The Lower Confidence Level (LCL) is calculated for the first and second shots by combining shot locations, plate sizes and environmental conditions. The LCL must meet or exceed the requirement specified in Table B.3.

B.2.2 Back Face Deformation Analysis. For BFD, the metric of merit is a one sided UTL based on the assumption of normally distributed BFD data; the UTL to be calculated as specified in Table B.3 The UTLs are calculated for the first and second shots by combining shot locations, plate sizes and environmental conditions as identified in section 3.7.

CUI

B.2.3 Fair Hit/No Test Criteria. Fair hit/no test criteria are defined as outlined in Table B.4 below. In the case of an under-velocity shot which results in either a system complete penetration or a BFD greater than 44mm, the shot result shall be included in the analysis. If the under-velocity shot occurs on the first shot, the plate shall be replaced with a contingency plate to ensure a completed test matrix.
