NIJ Armor Ratings: 0101.06 vs. 0101.07 Explained
NIJ 0101.07 uses RF1, RF2 and RF3 rifle-threat designations, while older requirements use Level III and Level IV. Level III+ and III++ are not official NIJ levels, so compare plates on documented rounds, reports and tested configuration.
National Institute of Justice (NIJ) armor ratings create real procurement risk when a request for quotation (RFQ) uses legacy Level III language, a product sheet uses RF2, and another vendor adds one or two "plus" signs without showing the test record behind them.
At a glance
- Start with the threat requirement: A plate label is only useful when the required rounds are clearly defined.
- Separate official terms from marketing names: Level III+ and III++ are manufacturer conventions, not official NIJ protection levels.
- Request the ballistic report: Verify tested rounds, configuration, lab documentation, and reported results before treating products as comparable.
- Review the complete issued system: Standalone setup, required add-ons, multi-hit documentation, warranty, and supply readiness all affect the procurement decision.
- Write measurable RFQ language: Define the required threat package and documentation instead of relying on "plus" terminology alone.
Short answer: NIJ 0101.07 uses RF1, RF2, and RF3 rifle-threat designations, while older requirements commonly use Level III and Level IV. Level III+ and III++ are not official NIJ protection levels; compare plates using documented test rounds, independent reports, tested configuration, and warranty terms, not plus signs alone.
For quartermasters, procurement officers, unit leaders, and prime contractors, the practical question is not simply what a plate is called. It is whether the documentation supports the threat requirement, whether the tested configuration matches the issued configuration, and whether the manufacturer can support the order.
Why NIJ Armor Ratings Create Procurement Confusion
Short answer: Buyers now encounter legacy NIJ labels, newer RF labels, and manufacturer-created "plus" terminology at the same time. Similar labels do not guarantee the same tested rounds, conditions, configuration, or evidence package.
A department can have an established requirement that says "Level III+." A current product sheet can use RF2. A third vendor can describe a plate as "III++." Those labels may appear together during a single procurement review.
They should not be assumed to mean the same thing.
The common mistake is treating the label as the proof. A plus sign does not identify the exact added threat. It does not identify the test laboratory. It does not show whether the plate was tested as a standalone plate or with supporting components. It does not tell a procurement team whether the report is available for review.
For institutional buyers, ambiguity becomes an operational problem. Equipment must be specified, purchased, issued, inspected, and replaced under a process that other people can understand and defend. A vague armor requirement creates questions for the contracting office, the prime contractor, the manufacturer, and the personnel receiving the gear.
Use the rating label to begin the review. Then ask for the evidence behind it:
- Exact rounds tested
- Identified standard, protocol, or test conditions
- Independent laboratory report
- Plate size, curvature, and configuration tested
- Backface deformation data where available
- Standalone or component-dependent setup
- Multi-hit testing documentation
- Warranty terms
- Manufacturing and fulfillment capability
That turns an armor comparison into a procurement-ready evaluation.
NIJ Armor Ratings Under 0101.06: Legacy Level III and Level IV
Short answer: Level III and Level IV were official rifle-protection categories under the NIJ 0101.06 framework. Verify their exact test ammunition, velocities, conditioning, and acceptance criteria against the official standard rather than relying on a product headline.
Legacy terminology remains important because it is embedded in older specifications, product searches, internal purchasing documents, and some open solicitations.
Under NIJ 0101.06, Level III and Level IV were defined protection categories with specified testing requirements. That is different from a manufacturer selecting a familiar label to position a product in the marketplace.
Even an official category is not a complete buying decision.
Two plates can both be associated with a Level III-type requirement and still differ in weight, thickness, curvature, construction, documented threats beyond baseline requirements, multi-hit evidence, and required accessories. The same is true for products positioned for higher rifle-threat requirements.
The issued plate must work as a complete system, not just as a line item on a product sheet. Review the plate, carrier compatibility, required add-ons, report package, inspection process, replacement policy, and deployment environment together.
NIJ Armor Ratings Under 0101.07: RF1, RF2, and RF3
Short answer: NIJ 0101.07 uses RF1, RF2, and RF3 as rifle-threat designations. Before treating an RF label as a procurement match, confirm the official threat requirements and compare them with the vendor's documented test results.
The newer terminology uses RF, meaning rifle threat. That is why RF1, RF2, and RF3 appear more often in current documentation and updated procurement conversations.
The important point is not to force a simple one-line conversion from old labels to new ones. Buyers often ask whether RF2 is "just Level III+." That comparison is too loose because Level III+ was never a standardized official category.
If a solicitation calls for RF2, the evaluation team should confirm:
- The applicable standard version
- The required threat set
- The plate size and configuration being quoted
- The independent test documentation supplied
- Whether the tested product matches the proposed delivered product
- Any agency-specific requirements beyond a baseline standard
This is particularly important in prime/subcontractor procurement. Clear documentation protects the agency issuing the requirement, the prime managing compliance, and the manufacturer supplying the equipment.
Legacy Levels vs. RF Ratings: Use a Crosswalk, Not a Shortcut
Short answer: A legacy-to-RF crosswalk can help interpret older requirements, but it cannot replace documented test evidence. "Closest equivalent" language becomes unreliable when the threat set, protocol, or plate configuration differs.
A translation table can orient a buyer. It should never substitute for a report review.
- Level III: Official legacy requirement, report, documented rounds, and tested configuration
- Level III+: Manufacturer-defined added threats, independent report, and exact meaning of "plus"
- III++: Manufacturer-defined threat package, report, configuration, and terminology explanation
- RF1, RF2, or RF3: Applicable 0101.07 requirement, documented test rounds, independent report, and agency-specific conditions
The better question is not, "What is this closest to?"
The better question is, "Does this plate's documentation support the threat requirement we need covered?"
If the operating requirement involves M193, M855/SS109, 7.62x39, 7.62x51, 7.62x54R, or another specific threat, write that requirement clearly. Then request the report showing what was tested. A plate should not be presumed to cover a round because of a plus sign in its name.
What III+ and III++ Actually Mean
Short answer: III+ and III++ typically signal that a manufacturer is claiming performance beyond a baseline Level III-style product position, but the added threats are not universal between brands. Request the documented rounds and test report before using either label as a purchasing requirement.
There is nothing inherently wrong with a manufacturer using III+ or III++ as a product name. The issue is whether the buyer can see what that name represents.
One manufacturer may use III+ to describe testing against one 5.56 threat. Another may use the same label for another threat package. A third may use III++ as an internal tier name. None of those uses creates a universal standard.
That is why "Level III+" by itself is weak RFQ language. It can create unlike-for-unlike comparisons, with vendors responding to different assumptions about the required threat package.
A stronger review asks every vendor:
- What exact rounds were tested?
- Which laboratory conducted the testing?
- Is the full ballistic report available?
- What test protocol or conditions are identified?
- What backface deformation results were recorded, where applicable?
- Was the plate evaluated standalone?
- What multi-hit testing is documented?
- What warranty applies?
ArmorIQ uses 3++ as a product-tier name, not as an official NIJ level. Our plates are not listed on the NIJ Compliant Products List. They are independently tested at a National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory, and the reports are available in an evaluation. We list the 3++ for 7.62x51 full metal jacket (FMJ), 7.62x54R, 5.56x45 SS109 (mild steel core, MSC), and .30-06 FMJ. The 3++ was tested at the Beretta Test Center in Gardone Val Trompia, Italy, to our protocol. Report 488/2026 records six shots on one plate, three 7.62x51 mm NATO FMJ and three 5.56x45 mm SS109, with no penetration and backface deformation of 2, 2, 1, 0, 0, 0 mm.
The useful takeaway is direct: do not assume every III++ plate means the same thing. Review the evidence for the specific product being evaluated.
ArmorIQ Plate Tiers Across the Legacy and RF Naming Eras
Short answer: ArmorIQ offers two plate tiers, the HG2 Special and the 3++. Compare them by documented threat coverage, independent test-report availability, plate configuration, and warranty, not by a label alone.
Our plate line is built around two tiers. The naming helps buyers navigate the line. The documentation is what enables a defensible comparison.
- HG2 Special: We list the HG2 Special for .44 Magnum and 7.62x39 FMJ (AK-47). It was tested at Energetic Test Labs in Phoenix, Arizona (NVLAP accredited, Lab Code 600369-0), under the conditions of NIJ 0101.07, V0. Report ETL-TR-AIQ-25-124-0103 (May 2025) records three shots of 7.62x39 mm MSC at 2,400 ft/s, no penetration, and backface deformation of 7.9 to 11.2 mm.
- 3++: We list the 3++ for 7.62x51 FMJ, 7.62x54R, 5.56x45 SS109 (MSC), and .30-06 FMJ. 3++ is our product-tier name, not an official NIJ level. Beretta Test Center report 488/2026 records six shots on one plate with no penetration.
Our plates are manufactured in the United States or in Italy, depending on the order, and carry a 12 year warranty on ballistic plates.
Our plates are patented and built on a proprietary ballistic alloy core with an integrated polymer layer system. Each plate is built for a carrier that already has the padding in it, so the issued setup is one assembly, with no pad to add.
For an issuing agency, standalone configuration is an operational question. Fewer required components can mean fewer pieces to purchase, track, install, inspect, and replace. The exact issued setup should still be confirmed against the applicable product documentation.
We also measure and record every shot, six per plate on the 3+++. That is separate from a rating label. Ask what was tested, how it was tested, and what the report records.
How to Compare Armor Plates Without Being Misled by a Rating Label
Short answer: Compare plates using verified documentation: rounds tested, laboratory report, protocol or conditions, backface deformation (BFD) results where available, standalone setup, multi-hit evidence, warranty, and fulfillment capacity. The label should begin the review, not end it.
Use this sequence when reviewing a vendor submission.
1. Define the threat requirement
Start with the threats the plate must address for the mission, policy, or solicitation. If a requirement says III+, define the actual threat package behind that term before requesting quotes.
2. Request the report
Ask for the independent ballistic report, not only a product graphic. Confirm the tested round, plate size, configuration, shot pattern, and stated conditions.
3. Review BFD information in context
Backface deformation is part of the protection discussion because penetration is not the only outcome buyers consider. Review reported BFD results in the context of the applicable testing requirements and your agency's equipment standards. The NIJ standard allows backface deformation of up to 44 mm and verifies that limit on the first two shots. ArmorIQ measures and records every shot.
4. Confirm the deployable configuration
Do not assume the quoted plate is complete as issued. Confirm whether trauma pads, spall sleeves, soft armor, or other components are required for the setup being evaluated.
5. Compare lifecycle terms
Initial purchase cost is not the full procurement picture if a system requires added components or more frequent replacement. ArmorIQ provides a 12 year warranty on ballistic plates. Review warranty coverage alongside inspection procedures, storage conditions, replacement policy, and deployment requirements.
6. Confirm supply readiness
For bulk requirements, ask where the plate is made, what documentation is available, whether the manufacturer can meet the delivery schedule, and whether custom carriers, vests, or system components can be supplied to specification.
A Better Way to Write a Level III+ or RF2 Requirement
Short answer: Do not use an informal label by itself. A stronger RFQ defines required threats, documentation, plate configuration, and evaluation criteria so vendors respond to the same measurable requirement.
If an existing specification says "Level III+," add the precise threats your department expects the plate to address. Require independent documentation supporting those threats.
If the requirement says "RF2," identify the applicable standard version and require documentation for the proposed plate configuration and any agency-specific conditions.
A well-written armor requirement can request:
- Plate model, size, and curvature
- Documented rounds tested
- Standard or test conditions identified
- Independent lab report
- BFD results where available
- Standalone or component-dependent configuration
- Multi-hit documentation
- Warranty terms
- Country of manufacture, if required
- Quantity, delivery schedule, and custom-equipment needs
That language makes evaluation cleaner. It protects the agency from vague claims, gives the prime a defined compliance target, and lets manufacturers respond to requirements they can document.
Need Help Matching a Plate to Your Requirement?
Short answer: ArmorIQ can help institutional buyers and prime contractors review requirements against documented threat coverage, available ballistic reports, standalone configuration, bulk supply needs, and custom tactical-gear requirements.
If you are updating a legacy Level III+ requirement, reviewing RF terminology, or comparing plate documentation across vendors, start with the threat requirement and the evidence, not the marketing label.
We supply armor plates, manufactured in the United States or in Italy depending on the order, along with carriers, vests, bulk supply, and custom tactical gear for institutional requirements. Full reports for the HG2 Special and the 3++ are shared as part of an evaluation. Submit your requirement for a technical review and a bulk or custom-equipment discussion.
