3. REQUIREMENTS

3.1 First Article. First Article Testing (FAT) is a requirement for IMBP. Samples shall be subjected to FAT in accordance with paragraph 4.1.1.

Commented [DG9]: This isn’t cited anywhere in the PD

Commented [DM10R9]: If we’re not talking about it, why are we referencing? Is citing the TOP enough?

Commented [DG11]: This isn’t cited anywhere in the PD

Commented [DG12R11]: This is cited in TOP 10-2-210 for Fluid resistance verification as part of ballistic testing, but we may need to cite in Appendix E should we deem it necessary to test buoyancy in sea/salt water versus freash water (which could impact results).

Commented [DG13R11]: MBP is test in distilled water (but buoyancy isn’t measured (go/no go if it floats)

Commented [DM14R11]: ASTM D 1141 is called out in MAS and NTV PDs in the ballistic test conditions sections but not in the buoyancy section, recommend we either keep the reference for all or remove from all

Commented [DM15R11]: If we’re not talking about it, why are we referencing? Is citing the TOP enough?

Commented [C(19R18]: I agree with keeping this in bc we use 44.0mm BFD from this.

CUI

3.2 Construction. The materials selected by the contractor shall be capable of meeting all the performance, operational and environmental requirements specified herein.

3.2.1 IMBP Cover. The IMBP cover materials shall mitigate frontal spall, increase durability, and decrease environmental deterioration of the underlying components configuration. The cover material shall cover the entire front and back outer surface and all side edges. The cover, including all edges, shall be free of cuts, holes, tears, abraded areas, wrinkles, bubbles or creases. The cover shall not exhibit any areas of under adherence. There shall be no visible peeling, wrinkles, bubbles or creases of the cover before or after any operating environment conditioning when verified in accordance with section 4.5.

3.2.1.1 Covering of Components by Spray Coating. The IMBP shall exhibit uniform coverage of any spray coated material. The finished plate shall exhibit no smears and/or clumps on the exposed surfaces or spray coated material, nor exhibit any under covered areas on exposed surfaces.

3.2.2 Assembly of Components by Bonding. The IMBP shall exhibit no evidence of under adherence between layers or components. The finished IMBP shall exhibit no smears and or clumps from excess bonding agent visible on the exposed surfaces when verified in accordance with 4.2.

3.3 Production Data. The following information, determined during production, shall be made a matter of record and shall be furnished on request to the contracting official.

This data shall be identified with the serial number of the body armor.

a. Data generated during inspection or other protocols per quality system/quality validation plan. This includes, but is not limited to, weight, thickness and dimensional measurements.

b. Supplier lot information and traceability for all component parts identified in the technical data package. This shall include material compliance forms signed by the contractor, each sub-contractor or material supplier.

c. Operational, ownership and environmental test data generated by the contractor on the IMBP.

d. Ballistic performance test data generated under all first article, conformance and validation testing as described in paragraph 4.8.

e. For traceability, every IMBP shall be durably marked in such a fashion as to be traceable from production through to the ballistic test records for that lot of IMBPs. The serial number shall be marked on the outside face within 1 inch

Commented [DM20]: I think this is meant to reference 4.5 operating requirements

Commented [C(21R20]: Agreed - good catch!

Commented [DM22]: Mention RFID here?

Commented [C(23R22]: hmm, not sure. Was that what Dave wanted for plates moving forward?

Commented [KK24R22]: Although we don’t know exactly how we will implement RFID, we do intend to transition to that technology for inventory management across the board.

Theoretically, if a tri-wall of armor (or anything we manage) comes in from the vendor, RFID would allow us to know every plate in that box without opening it up. I have also discussed with Desiree how we could have NTV manufacturers incorporate RFID into NTV (eventually).

Commented [C(25R22]: I don't know if we can afford, especially if it doesn't come to fruition. Is there a way we can get a cost estimate? Also, who pays for the warehouse equipment and installation?

Commented [KK26R22]: We are still working out details and don’t have cost estimates at the moment. While there may/will be an upfront investment, we will be able to provide you an accurate (99%) wall to wall inventory in as little as a day vs 2 weeks with questionable accuracy.

It will come to fruition, it has to, and will result in long term cost savings for annual wall to wall, inventory receipt etc.

Commented [C(27R22]: Two weeks... ahh Kevin you are such a jokester - We are still waiting on the 2024 inventory. I think we are about five months away from a two-year turnaround time.

Commented [DM28R22]: Leave this paragraph as is for now.

Revise once we have more info about RFID

Commented [KK29R22]: Annual inventory has not been our strong suit to be sure. I was referring to conducting the physical inventory which has historically taken 2 weeks. You are spot on that the 2024 is WAY overdue from completion. We are going to change that.

Commented [KK30R22]: At least include language that gives the option of going to RFID. The PWS should be written accordingly.

Commented [DM31R22]: Provide RFI stickers as GFM to the manufacturer, adhere behind sticker on flat surface?

Commented [DG32R22]: This particular paragraph is referring to marking on the actual ceramic strike face prior to plate assembly.

CUI

of the lower edge of any ceramic component (if used) before it is fired. It shall be marked by inscribing, embossing, or with high temperature resistant inorganic ink after firing with permanent marking to a maximum depth of

0.010 inch so that the serial number will be legible when the cover is stripped mechanically or by the use of a solvent. Solvents, fuels and other liquids shall not affect the serial number markings. It is desirable to have ceramic cores marked to be traceable by radiographic analysis as well. If inscribed, it will be done on the outer 0.25 inches of the plate.

3.4 Workmanship. The finished IMBP shall conform to the quality of product established by this purchase description. Utmost care shall be taken during fabrication to ensure quality workmanship and safety of the service person using the item. All materials to be used in the construction of the IMBP shall conform to all material requirements in this purchase description and internal specifications, unless otherwise specified.

Manufacturing practices shall be capable of consistently yielding product that conforms to all requirements in this purchase description and internal specifications for the body armor and their components. Continual improvement shall also be a constant focus of the manufacturing practice. All component materials shall be properly marked and identified and shall be protected properly during storage.

Materials shall be produced and integrated to extend durability and provide consistency of appearance throughout plate life. All components to be assembled shall be thoroughly cleaned of all foreign matter. Surfaces to be bonded shall be properly prepared in a manner which will ensure a proper bond capable of meeting the applicable performance requirements. The required adhesive(s) shall be applied uniformly over the entire contact areas of the components to be joined to eliminate delamination between materials. Material layers shall be free of contaminants (such as, but not limited to: Foreign Object Debris (FOD) (media not associated with the technical data package), loose fragments of component materials, operator elements not part of component materials. Any IMBP ceramic (if used) must be free of cracks.

Defective conditions within the IMBP shall not exceed the limits identified in Table D.1 (Appendix D). This section is applicable to all material or components of the IMBP whether furnished by the Prime Contractor or by any of their suppliers or sub-contractors. In any case of material, process, or equipment change desired to be made by the Contractor, the written consent of the Government shall be obtained before making the change. Additional testing may be required prior to implementation of the change to verify product performance. (See section 4 for verification).

3.4.1 Uniform Areal Density. The IMBP shall provide uniform areal density

(materials coverage) throughout the entire surface area. The only exception shall be when edge materials are used to protect the plate from side impact (e.g., foam) to increase the durability. Material no thicker than 0.10 inches (2.54 mm) may be used for this purpose. Materials shall extend from edge to edge to provide uniform thickness throughout the entire surface area of the IMBP. “Patches,” “clamps,” and other materials with partial or interrupted

CUI

coverage of the IMBP surface area shall not be acceptable. Materials shall not cause interference with Non-Destructive Test Equipment (NDTE) (e.g., radiographic inspection or computed tomography). If ceramic materials are used, the ceramic shall have uniform edges. To reduce sharp edges, an abrasive device or other equipment may be used to clean the edges in production. Uniform areal density shall be verified in accordance with paragraph 4.2.2.3.

3.5 Operational Requirements. IMBP are neutrally buoyant, multi-curve, hard armor plates intended for use in multiple armor systems. Each IMBP shall meet the following user-oriented requirements (see paragraph 4.5).

3.5.1 Ease of Insertion. The IMBP shall be able to easily slide into and out of the corresponding sized Maritime Armor System (MAS) and Naval Security Forces (NSF) Tactical Vest (NTV) plate pockets. No special training, equipment or tools will be required to insert the IMBP into the plate pocket (see paragraph 4.5.1).

3.5.2 Weight. The finished IMBP threshold (maximum) and objective (desired) weights are outlined in Table 1 (rounded to the nearest 0.1 lb) (see paragraph 4.5.2).

Table 1. IMBP Maximum Weight

3.5.3 Dimensional Measurements. The IMBP shall conform to all measurements, tolerances, radius and edge chamfers as specified in drawings listed in paragraph 2.2.2 (see paragraph 4.5.3). Appendix D outlines applicable out of tolerance grading scale for determination of acceptance.

3.5.4 Thickness. The IMBP in finished form shall have a maximum 1.0-inch uniform thickness throughout. The variability of the local thickness on any part shall not exceed 1/8 inch (see para. 4.5.4).

3.5.5 IMBP Color. All outer areas of the IMBP shall be colored Black and be a good match to the standard sample (see paragraph 4.5.5).

Commented [DM33]: Add CT-scan here?

Commented [C(34R33]: I don't see what it would hurt

Commented [KK35]: I don’t recall if we know that these weights, for the respective volume of plate, will result in positive buoyancy.

Commented [C(36R35]: I know for a fact the Small-Short is a SWAG (don't ask me how I know). The rest are accurate for the Threshold.

Commented [DM37R35]: NCTRF has all sizes of plates to get dry weight and buoyancy, will update once we get the results

Commented [DG38]: Keeping X-Small incase other services are interested. We can discuss further, but test matrix does include it.

Commented [DG39]: Need to get weights for Small short

Commented [DG40]: Specify shade?

Commented [DM41R40]: specify the “standard sample” from par. 4.5.5

4.1.1 First Article Testing (FAT). The government reserves the right to perform any of the tests set forth in this specification where such tests are deemed necessary to ensure supplies and services conform to prescribed requirements. When a FAT is required, it includes all of the verifications listed in Table 2 unless otherwise specified in the contract.

4.1.2 Lot Acceptance Testing (LAT). LAT sample test size shall be determined using ANSI/ASQ Z1.4-2008, Special Inspection Level S-4, AQL of 4, single sampling plans for normal inspection. LAT of IMBP shall include those applicable examinations and tests outlined in Table 2. Refer to Appendix C for LAT Protocol.

4.2 Requirements and Verifications. Table 2 delineates performance requirements and the associated verification methods.

Commented [GDCUPUW(59]: Believe this is covered since we provide drawings and verify dimensional accuracy.

CUI

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.

4.3 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.

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.
