***Ballistic Resistance of Body Armor***

**January 2018**

**Introduction**

This draft document specifies minimum performance requirements and test methods for the ballistic resistance of body armor used by U.S. law enforcement that is intended to protect the torso against handgun and rifle ammunition.  It is a proposed revision of NIJ Standard 0101.06, *Ballistic Resistance of Body Armor*, published in 2008.[footnoteRef:1] The final version of this document is anticipated to be published in late 2018 as NIJ Standard 0101.07.  Its primary purpose will be for use by the NIJ Compliance Testing Program (CTP) for testing and evaluation of ballistic-resistant body armor for certification by NIJ.  It will be used by both ballistics laboratories that test body armor and body armor manufacturers participating in the NIJ CTP.  This standard will be included in the Personal Body Armor scope of accreditation used by the National Voluntary Laboratory Accreditation Program (NVLAP) to accredit ballistics laboratories. [1:  NIJ Standard 0101.06, Ballistic Resistance of Body Armor, National Institute of Justice, U.S. Department of Justice, Washington, DC, July 2008, https://www.ncjrs.gov/pdffiles1/nij/223054.pdf.] 

There are some departures in format from NIJ Standard 0101.06.  First, standards describing various test methods and practices are incorporated by reference into this document, including those for soft armor designed for female wearers.  NIJ, the U.S. Army, the National Institute of Standards and Technology (NIST), and others have been cooperating to harmonize laboratory test procedures and practices in ASTM Subcommittee E54.04 on Personal Protective Equipment within Committee E54 on Homeland Security Applications.[footnoteRef:2] Unlike the current and previous versions of the NIJ standard which have been comprehensive, standalone documents, revision 0101.07 will incorporate by reference a suite of standardized test methods and practices developed in ASTM E54.04.  Incorporation of relevant ASTM standards by reference into NIJ standards and U.S. Army requirements and testing documents, for example, affords the opportunity to harmonize laboratory test procedures and practices for both law enforcement and military ballistic-resistant armor and other ballistic-resistant equipment while providing those end user communities ultimate control over product specifications, such as the specific threats against which their equipment must protect. [2:  “Subcommittee E54.04 on Personal Protective Equipment (PPE),” ASTM International, West Conshohocken, PA, https://www.astm.org/COMMIT/SUBCOMMIT/E5404.htm.] 

Second, the ballistic test threats have been removed to their own standalone specifications document that defines ballistic threats identified by U.S. law enforcement as representative of prevalent threats in the United States.  Currently in draft form, this document specifies the threat levels and associated ammunition intended for use with voluntary NIJ Standards that specify a minimum performance requirement for equipment intended to protect U.S. law enforcement against handgun and rifle ammunition.  A standalone threats specification may also enable testing of a variety of ballistic-resistant equipment, not just ballistic-resistant body armor, against contemporary U.S. law enforcement threats.

Third, threat level nomenclature has been revised to be more descriptive of threats and to reduce confusion among law enforcement end users of body armor.  Level II and level IIIA have been replaced with “HG1” and “HG2,” respectively, to represent handgun (HG) threats.  Level III and level IV have been revised to three levels representing rifle (RF) threats—“RF1,” “RF2,” and “RF3”—with RF1 and RF3 replacing level III and level IV, respectively.  RF2 is a new intermediate threat level introduced in this draft version of NIJ Standard 0101.07.

This document uses the following in accordance with international standards:

· “shall” indicates a requirement;

· “should” indicates a recommendation;

· “may” indicates a permission;

· “can” indicates a possibility or a capability.

1. **Scope**

1.1. This standard specifies minimum performance requirements and test methods for the ballistic resistance of body armor used by U.S. law enforcement intended to protect the torso against handgun and rifle ammunition.

1.1.1. The test methods within this standard were developed and validated for broadly available armor designs. Some armor designs may require additional or different testing than that specified in this standard.

1.2. Body armor covered by this standard is classified into five protection levels: NIJ HG1, NIJ HG2, NIJ RF1, NIJ RF2, and NIJ RF3. 

1.3. This standard also addresses hard armors that are intended to provide the stated level of ballistic protection only when paired with a specific model of soft armor. This type of armor is referred to as *in conjunction with* (ICW) armor, and addressed within protection levels NIJ RF1, NIJ RF2, and NIJ RF3. 

1.4. This standard is applicable for certification testing or research and development testing.

1.5. This standard incorporates other standards from ANSI/SAAMI, ASTM International, and ISO/IEC.

1.6. Values stated in either the International System of Units (metric) or U.S. Customary units (inch-pound) are to be regarded separately as standard. The values stated in each system may not be exact equivalents. Both units are referenced to facilitate acquisition of materials internationally and minimize fabrication costs. Tests conducted using either system maintain repeatability and reproducibility of the test method and results are comparable.

1.7. **The tests required by this standard have inherent hazards. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations.**

# **Annex A (Mandatory): Procedure for Soft Armor Conditioning by Tumbling**

### 1. Scope

### 1.1. This procedure applies only to the conditioning of soft body armor test items via temperature, humidity, and tumbling exposure prior to ballistic resistance testing.

### 1.2. The purpose is to subject test items to conditions intended to provide some indication of the test item ability to withstand conditions of heat, moisture, and mechanical wear (folding and abrasion) that might be encountered during wear.

2. **Test item preparation**

2.1. Test items shall****be conditioned at controlled ambient as defined in ASTM E3078 for at least 24 hours prior to this procedure. This may be achieved in a controlled laboratory environment, or if conditions in the laboratory deviate from those specified, a chamber may be used to create these conditions.

2.2. The test items shall be stored flat prior to and following this procedure. Note: Stacking of test items is permitted.

### 3. Laboratory Configuration and Test Equipment

### 3.1. Environmental chamber

### 3.1.3.        The environmental conditioning relative humidity shall be 80% ± 5%.

### 3.2. Tumbling Apparatus

3.2.1. A rotating drum shall be used to generate the tumbling action and shall have a rotation rate of 5.0 rpm ± 1.0 rpm. The drum rotation rate may be varied within the given tolerance to achieve the necessary number of rotations and the rotation rate shall not exceed the specified tolerance.

3.2.2. The drum shall be constructed from stainless steel.

3.2.3. The tumbling apparatus shall maintain tolerances of temperature, humidity, and revolutions per minute specified in this section.

3.2.4.2. Internal depth: 	 25 5/8 in ± 1/4 in (651 mm ± 6 mm)

3.2.4.3. The drum shall have four fins (i.e., ribs) running the full depth of the drum spaced at 90o intervals about the circumference. Each fin shall be 4 1/2 in ± 1/8 in (114 mm ± 3 mm) high. The top edge of each fin shall be rounded with a minimum diameter of 3/4 in ± 1/8 in (19 mm ± 3 mm). The base of each fin shall not be thinner than 3/4 in (19 mm) and shall not be wider than 3.0 in (76 mm).

3.2.4.4. The rotating drum shall have smooth inner surfaces with no sharp edges, no rough spots, and no burrs.

### 3.2.5.        The rotating drum shall have sufficient openings to allow air flow such that the air inside the drum remains within the specified tolerances for temperature and humidity. In order to achieve this, the drum wall shall be perforated.

### 3.3. Environmental chamber and tumbling apparatus monitoring

3.3.1.       The monitoring equipment shall include measurement and recording device(s), independent from the chamber and tumbling apparatus controllers.

### 3.3.2.       The monitoring equipment shall provide and allow documentation of temperature and relative humidity measurements inside the environmental chamber.

### 3.3.3.       The laboratory shall monitor and document:

· Time and date at beginning and for each time the rotation count is recorded

· Temperature

· Relative humidity

· Revolution rate

· Rotation count

### 3.3.4.       The humidity chamber shall be designed in a manner that minimizes condensation coming into contact with the test items to the extent possible.

### 4. Conditioning Procedure

### 4.1. Duration

### 4.1.1.       The conditioning duration shall be 240 hours ± 1 hour.

4.1.2. The drum shall be rotated through 72,000 ± 1,500 complete rotations during the test. 

4.1.3. Figure 1 shows acceptable conditioning procedure end points given the combination of time and drum rotation. The procedure is complete and may be stopped when time and drum rotation fall within the box shown in Figure 1.

### 4.2. The conditioning procedure is detailed below:

4.2.1. Verify the apparatus maintains conditions within the tolerances specified at periodic intervals throughout the conditioning activity.

4.2.2.       Unless otherwise specified, continuously measure and document the analog temperature and relative humidity during the procedure. Conduct digital measurements at intervals of 10 minutes or less.

Figure 1: Criteria for the end of the conditioning activity.

4.2.3.      Use only instrumentation with the selected environmental conditioning chamber that meets the accuracies, tolerances, etc., described herein.

4.3. Load the test items into the tumbler, one at a time, such that test items are positioned arbitrarily to each other (e.g., not in an orderly stack).

4.4. Initiate the conditioning process.

4.5. At least once per working shy , observe the test items in the chamber using a viewing port or remote camera system to determine if the test items are tumbling freely. 

4.5.1. If any test item experiences an unfair tumbling condition, such as being trapped between the rotating and static portions of the tumbler, then that test item shall be removed from the tumbler and inspected. Any damage to that test item shall be documented, and the test item shall be marked to indicate that it is not to be subjected to ballistic testing. That test item shall then be flattened and returned to the tumbler to keep the load in the tumbler constant. 

4.6. Monitor the tumble count and calculate the rate to ensure that the tumbling requirements are continuously met.

4.7. At the end of the conditioning process, power down the apparatus, and remove the test items from the tumbler within 30 minutes of cessation of tumbling. 

**Note:** Ideally, removal from the tumbler should be completed within minutes for the purpose of ensuring that the test items are removed before they cool to room temperature.

4.8. Following conditioning by tumbling, examine the test items for visible excessive wrinkling or damage due to conditioning. Photograph and otherwise document any test items showing such damage. 

4.9. Stack the test items on a flat surface in controlled ambient conditions. 

4.10. Place the most wrinkled test items on the bottom, straightening and smoothing them as much as possible. Then stack remaining test items on top of the most wrinkled test items to help press out the wrinkles. Test items shall remain stacked for at least 12 hours.

4.10.1. If these procedures are not sufficient to return the test items to a condition that is acceptable for ballistic testing, additional smoothing procedures, described in Section 6, may be necessary.

4.11. When it is necessary to ship the test item to a ballistic testing laboratory, package the test items securely to prevent them from becoming folded, wrinkled, or moved about in the container during shipment. The stacked orientation should be preserved with the flattest test items on top and more wrinkled test items on bottom to improve the chances that the test items will be flat when they reach the ballistic testing facility. 

4.12. Test items shall be stored at the ballistic testing facility under controlled ambient conditions for at least 12 hours prior to any ballistic testing.

4.13. The documentation required in section 7 shall be provided to the ballistic testing laboratory.

5. **Environmental Chamber Door Opening Guidelines**

5.1. Prior to opening the chamber or entering a walk-in chamber, reduce the humidity in the chamber prior to reducing the temperature to avoid generation of condensation in the tumbler. 

5.2. Stop the drum rotation. 

5.3. The amount of time that the conditioning procedure is paused shall be made up at the end of the protocol.

6. **Opening a Test Item for Additional Smoothing**

6.1. If necessary, and after all other attempts to flatten one or more test items have been exhausted, then the affected test items may be warmed in an environmental chamber, with conditions of 1 hour ± 10 minutes at 45 C and 50% relative humidity, with the same tolerances of temperature and relative humidity as specified in Section 3.1. Only the affected test items should be placed in the chamber for rewarming. 

6.2. The preceding stacking procedure shall be repeated in an effort to flatten the test items. If this is necessary, then describe what was done in detail in the test report. This rewarming may only be performed one time on each batch of test items.

6.3. If necessary, and after all other attempts to flatten a test item have been exhausted, the test item may be removed from its carrier and the test item panel cover may be slit to assist in flattening the test item.

6.3.1. Horizontally slit only the test item panel cover (not the ballistic panel) with a razor blade near the bottom of the test item.

6.3.2. Fold the test item panel cover back to access the part of the test item that requires flattening.

6.3.3. Immediately mark the strike face of the ballistic material to ensure that it will be reinserted with the correct orientation.

6.3.4. To reduce the possibility of an incorrect reinsertion of the ballistic material inside of the test item cover, if possible, keep the test item partially inside of the test item panel cover to help maintain its original orientation.

6.3.5. Flatten the ballistic material, including unfolding any corners or edges that may have become folded or dog-eared.

6.3.6. Re-insert the ballistic material through the opening in the panel cover, reversing the steps that were necessary for removal.

7. **Documentation of the conditioning activity**

# **Annex B (Mandatory): Equipment and Procedure for Conditioning by Submersion**

Equipment

The armor submersion equipment shall consist of a water bath sufficiently sized to allow at least one test item of the largest template size to hang vertically, without any folds or bends, with the top edge of the test item at least 4in (~102 mm) below the surface of the water, and with at least 2in (~51) mm clearance around the test item. 

The water in the bath shall be clean and shall be either potable tap or demineralized water. The water shall be replaced anytime there are visible impurities in the water. The water temperature shall be 70 °F + 5 °F/-10 °F. 

Procedure

Each test item shall be hung vertically in the water bath for 30 min (+ 5 min/- 0 min) with the top edge of the test item positioned 4.0 in ± 1.0 in (100 mm ± 25 mm) () below the water surface. For test items that are buoyant, weights shall be attached to the bottom edge with clothes pins or similar clips to allow the test item to hang vertically. After removing the test item from the water, it shall be hung vertically to drip dry for 10 min (+ 5 min/- 0 min) before mounting on the clay block for ballistic testing. 

# **Annex****C (Mandatory): Hard Armor Conditioning Procedure**

ASTM E3078 is applicable for the conditioning of hard armor test items. Test items shall be subjected sequentially to the two procedures from ASTM E3078 listed below:

1) Section 13, Impact Durability Pre-conditioning

2) Section 14, Impact Durability Conditioning Procedure for Torso Front and Back Plates

These procedures detail the equipment and laboratory configuration requirements.

No other procedures from ASTM E3078 shall be applied to the test items.

# **Annex D. (Mandatory) BFD Measurements**

When any BFD measurement exceeds 44 mm (1.73 in), then there shall be a 95% confidence that 80% of all BFD depths will be 44 mm (1.73 in) or less. This requirement can be verified using a statistical tolerance limit. It is expected that a stated portion of the entire population of all BFD measurements will lie at or below the statistical upper tolerance limit. To achieve this, the population of BFD measurements is assumed to be normally distributed, and the upper tolerance limit, BFDU, must be ≤ 44 mm (1.73 in). The upper tolerance limit is defined below:

Equation 1:	

BFDave is calculated as shown below:

Equation 2:	

*N* is the number of BFD measurements, and BFDi are the individual BFD measurements. The sample standard deviation, *s*, is calculated as shown below:

Equation 3: 	

The approximate k factor, *k1*, for a one-sided tolerance interval can now be calculated as shown below:

Equation 4:	

Here, *z*1-p is the normal distribution critical value that is exceeded with a probability of 1-p. The factors *a* and *b* are defined below:

Equation 5:	

Equation 6:	

Here, *z*1- is the normal distribution critical value that is exceeded with a probability of 1-. 

For the analysis of BFD measurements according to the requirements of this standard, the probability that no BFD measurement exceeds 44 mm (1.73 in) must be at least 80%, so p = 0.80, and the required confidence is 95%, so =0.95. The critical values for the normal distribution can be calculated or obtained from tables in statistical textbooks. For this case, they are: 

*z*1- = *z*0.05 = 1.645; *z*1-p = *z*0.20 = 0.842

**Table 1 below provides some k1 values based on the number of BFD measurements.

Table 1. k1 Values Based on Number of BFD Measurements

# **Annex E (Mandatory): Analysis of Ballistic Limit Data**

Once the ballistic limit testing has been completed, the test results shall be analyzed for each test threat by performing a regression to estimate the armor’s performance over a range of velocities. In particular, the analysis shall attempt to estimate the velocity where the probability of complete penetration becomes reasonably small. In general, a logistic regression can be used for this purpose; however, other probability distributions and regression methods may be used when one can be shown to better estimate the performance of a particular armor model.

The logistic regression may be performed on the data using the method of maximum 

likelihood to estimate the logistic parameters  and , which are the estimated *logistic*

*constant* and the estimated*velocity coefficient*, respectively. These parameters define the shape of the S-shaped logistic curve, which is defined as:

Equation 1:	

Here, **(*v*) is the is the probability of a complete penetration occurring at velocity, *v*. From the estimated logistic parameters, the ballistic limit can be determined as:

Equation 2:	

In addition, the velocity at which the probability of a complete penetration is *x*%, , can be determined as:

Equation 3:	

The estimated logistic parameters for a conditioned armor and its ballistic limit can be determined in the same method; however, care should be exercised when the analysis is performed on a relatively small data set, as the reliability of the estimated complete penetration probability will be poor for small data sets.

# **Annex****F (Mandatory): Test Item Size Templates**

This standard specifies five template sizes for testing soft armor test items:

1) NIJ-C-1 (smallest)

2) NIJ-C-2 (small)

3) NIJ-C-3 (medium)

4) NIJ-C-4 (large)

5) NIJ-C-5 (largest)

The dimensions of the templates are shown in the figures on the following pages.

# **Annex G. (Mandatory) Test Item Label Inspection and Durability Test**

**Test Item Label Content Requirements**

The label shall be permanently attached to the face of the panel. The label shall contain the following information (an example is provided in Figure 1):
Figure 1. Example Test Item Label

· Name, registered trademark, or other identification of the supplier.

· The rated level of protection and reference to this edition of the standard (e.g., NIJ HG1 in accordance with NIJ Standard-0101.07).

· A test ID number or model designation that uniquely identifies the armor design for testing purposes.

· The test item template size.

· A number or serial number that uniquely identifies each test item.

· Location of manufacture.

· The date of manufacture.

· Identification of the proper orientation of the ballistic panel (i.e., strike face or wear face).

· A warning in larger type than the rest of the type on the label that clearly emphasizes the warning, stating that the ballistic panel is a test item that has not yet been demonstrated to provide ballistic resistance and that the armor panel is not intended to be worn. Printing color changes are acceptable but cannot be substituted for the type size requirement herein.

**Armor Carriers with Non-removable Ballistic Panels**

Ballistic panels that are non-removable from the armor carrier shall, in addition to the label required for the ballistic panel, have a label on the armor carrier that is in conformance with the test item label requirements, unless the ballistic panel is so constructed that its label is not covered by the armor carrier. 

**Test Item Label Permanency and Durability**

All test item labels shall be sufficiently permanent and durable so that they will remain securely attached to the ballistic panel or armor carrier. The durability of the test item label markings shall be checked with the following procedure:

1) Rub by hand a representative area of the label text for approximately 15 seconds with a 100% knit cotton cloth soaked with distilled water. Within the 15 seconds, make 30 passes with only enough pressure to ensure contact between the cloth and the surface of the label. 

2) Rub the same area by hand for an additional 15 seconds with a 100% knit cotton cloth soaked with denatured alcohol (methylated spirit). Within the 15 seconds, make 30 passes with only enough pressure to ensure contact between the cloth and the surface of the label.

3) Finally, rub the same area by hand for an additional 15 seconds with a 100% knit cotton cloth soaked with isopropyl alcohol. Within the 15 seconds, make 30 passes with only enough pressure to ensure contact between the cloth and the surface of the label.

# **Annex H. (Mandatory) Soft Armor Designed for Female Wearers**

1. **Location of Shaping Features**

The technician shall determine the locations of stitches, seams, folds, and other shaping features that can be felt through the test item panel cover. If overlaps of material exist in the test item, the technician shall note the direction of overlap of the subcomponents of the test item. These features shall be marked on the carrier. 

2. **Shot location and angle marking**

The technician shall follow the guidelines below for clearly marking the six intended shot locations and angles directly on the carrier for each test item: 

1) Shot location markings for angled shots shall indicate the angle of incidence for that shot as well as the direction from which the shot will impact the test item. 

2) The shot patterns listed in Tables 1 and 2 of Annex H, Section 6 are for guidance purposes only and are subject to modification by the technician after observing test results. 

3) Typically, the shot location pattern for the first test item will follow the guidance provided below. The shot locations for subsequent test items should be modified as necessary based on observed results. 

4) No shot location shall be marked directly on a portion of material that is made up of more layers due to overlapping regions of material. 

5) It may be necessary to replicate a shot pattern from an individual test item. If any of the conditions below are observed during testing, the shot pattern on that test item shall be replicated on the subsequent test items:

a) When a complete separation in a section of the overlap region greater than the diameter of the bullet is observed, then that shot’s location, angle of incidence, and direction shall be replicated on subsequent test items. 

b) A particular shot location exhibited a BFD greater than 42 mm. (If the BFD on multiple shots exceeds 42 mm, the deepest indentation shall be replicated.)

c) A BFD that is 10 mm higher than the average of the other two BFDs is measured for a given test item.

3. **P-BFD Testing**

Shots shall be taken according to ASTM Standard E3107-17a with the following modifications:

#### 3.1. Edge shot pattern modifications

1) Marking of edge shots shall be varied from test item to test item unless one or more of the scenarios described in Annex H, Section 2, item 5 above are encountered. 

2) The requirement to vary the shot pattern shall not supersede any requirement listed in Annex H, Section 2 above. 

3) Because NIJ-C-1 sized test items do not have wing components, the shot location markings are not required to conform to the pattern shown in Figure 2 of ASTM E3107-17a. It may be necessary to invert the triangle formed by shots 1, 2 and 3 because placing shots 2 and 3 alongside a neck scoop allows the full 6-shot sequence to be marked on the test item. 

### 

### 3.2. Rules for Cluster shots

### 3.2.1. Shot 4

a) First test item of a given size

i) Shot 4 shall be used to challenge the apex of either the left or right bust cup. 

ii) For hybrid designs where multiple stitch patterns are used throughout the layup, the strike face stitch pattern shall be used to determine shot placement.

iii) For test items with bust cups formed by vertical seams, the shot shall be marked 12.7 mm to 25.4 mm (1⁄2 in to 1 in) away from the apex by moving it diagonally at approximately a 45° angle upward and toward the centerline of the test item. See Figure H1 for an example of shot markings. The offset distance shall increase if necessary to move the shot off any overlapping material that is a component of the seam. In this case, the shot shall be marked immediately adjacent to the overlap of material. This shot shall be angled toward the outside of the test item (i.e., away from the vertical centerline). 

Figure H1. Example Shot Markings

iv) For test items with a horizontal seam design, the shot shall be marked immediately adjacent to the overlap of material. For example, where the overlap forms a step on the strike face of the test item, the shot shall be placed on the low side of that step. This shot shall be angled toward the edge of the test item considered to be the neck and shoulder edge. 

See Figure H2 for examples of shot placement in regions of overlap.

Figure H2. Examples of Shot Placement in Regions of Overlap

b) Second test item of a given size

i) Unless overridden by the need to replicate an earlier shot, shot 4 on test item 2 shall:

(1) Challenge the other bust cup apex. 

(2) Be in the opposite direction than specified for the previous test item (e.g., if shot 4four on test item 1one was toward the edge of the test item, then shot 4four on test item 2two shall be toward the centerline). 

(3) Strike at a different angle of incidence than was used to challenge the previous test item. 

ii) The same modifications listed in Annex H, 3) above for horizontal and vertical seams shall be followed. 

c) Third and fourth test items of a given size

i) Shot 4 shall be used to challenge the intermammary cleft region.

ii) The default position shall be at the center point between the bust cup apex with approximately a 12.7 mm (1⁄2 in) offset to the outside edge. The direction of this offset shall change between test items 3 and 4. For test items where this position represents an overlap in material, the shot shall be offset to the nearest point on the test item where no overlap exists. 

iii) Shot 4 shall be marked to be taken towards the inside of the test item. 

3.2.2. Shot 5

a) Shot 5 shall be marked approximately 3.5 in (89 mm) below the shot marking for shot 4 following the surface of the test item. It shall be shifted slightly to the left or right to avoid marking both shots along the same vertical line.

b) For smaller test items, it may be necessary to consider the placement of shots 5 and 6 simultaneously. 

c) The marking of the placement for shot 5 may be altered by rotating the shot placement “triangle” around the origin of shot 4, ensuring that shot 5 does not impact a double thickness of material and that it is marked within the fair hit shot-to-edge distance. 

d) Shot 5 shall be aimed in the same direction as shot 4 (i.e., toward the left, right, top, or bottom of the test item). 

3.2.3. Shot 6

a) For the first test item of a given size in the test series, the sixth shot shall be marked approximately 89 mm (3.5 in), following the surface of the test item, from shot 4 and shot 5 such that shots 4, 5, and 6 will impact within a projected 100 mm (4 in) circle. 

b) The positioning of shot 6 shall be such that it does not strike an area of double thickness due to overlapping sections of material. 

c) With a horizontal arch stitch pattern, it may be necessary to consider the positioning of shots 5 and 6 at the same time to meet all requirements of this document. 

d) Shot 6 shall be at 0° angle of incidence.

### 

### 4. Shooting the test item

### 4.1. For shots 1, 2 and 3, attempt to use straps to hold the test item near the intended point of impact flat against the clay block. If the test item cannot be flattened onto the clay block due to material stiffness, then construct a suitable applique to fill in the air gap. The BFD measurement device shall be zeroed on the intended point of impact in such cases. 

### 4.2. Shots 4, 5 and 6 shall utilize appropriately sized appliques meeting the requirements of ASTM E3086 – 17. Appliques shall be replaced as necessary to support the test item.

### 5. Post shot inspection of test items

Inspect the test item immediately following each shot for any signs of possible weakening or damage resulting from the impact. In addition, once a test item of a given size has received all six shots, the test item shall be inspected to determine how it performed. 

### 6. Summary tables

**Annex I. Ballistic Limit Test Method**

This test method was excerpted from ASTM WK52176, Standard Test Method for Collection of Vx Ballistic Limit Data for Ballistic-resistant Torso Body Armor and Shoot Packs (not yet published.)

1. **Terminology**

1.1 *applique,*n*–*a**three-dimensional item molded from backing material that is shaped and sized for testing or conditioning a nonplanar test item. 

1.1.1 *Discussion –*Some appliques are designed for the purpose of filling the entire space behind a nonplanar test item; other appliques are designed to assess features of a nonplanar test item. (ASTM Practice E3086)

1.2 *angle of incidence*, n*–*the angle between the test threat line of aim and the line normal to a reference plane based on the front surface of the backing assembly or witness panel. (adapted from ASTM Terminology E3005)

1.3 *ballistic limit*, n*–*a measure of an item’s ballistic resistance to complete penetration expressed as a velocity associated with some probability of perforation.

1.3.1 *Discussion* – The item may be a test item, material, shoot pack, body armor, or other ballistic-resistant product.

1.4 *test series*, n*–*the set of all shots necessary to obtain the required number of fair hits on a single test item or the set of all shots necessary over multiple test items to generate the required data.

1.5 *warmer round*, n*–*a projectile fired from a receiver or firearm, prior to testing, to warm the test barrel.

2. **Test Equipment and Apparatus**

2.1 The ballistic test range shall meet the requirements of ASTM Specification E3062.

2.1.1 The method for measuring yaw may be with a yaw card, flash radiography, high speed video, or photography. 

2.2 When clay blocks are required to be used as backing assemblies behind test items, they shall meet the requirements of ASTM Specification E3004.

3. **Test Requirements**

3.1 Each ballistic impact shall meet the requirements listed below to be considered a fair hit. 

3.1.1 The test threat shall impact the test item at an angle ≤ 5° from the intended angle.

3.1.2 The test threat shall have yaw verified to be ≤ 3° for rifle threats or ≤5° for fragment and handgun threats. Yaw shall be checked for every test threat shot. 

3.1.2.1 The yaw measurement equipment shall be positioned perpendicular to the projectile line of flight. The yaw measurement equipment shall be securely mounted and anchored to maintain its required position and alignment.

3.1.2.2 When photographic means are used to assess the projectile yaw angle, the assessment shall be made as close as practical to the strike face of the test item but not more than 305 mm (12 in) from the front of the strike face.

3.1.2.3 When yaw cards are used to assess the projectile yaw angle, unless specified elsewhere, the cards shall be positioned between 51 mm (2 in) and 305 mm (12 in) from the front of the strike face of the test item.

3.1.3 The test threat shall impact the test item no closer to the edge of the test item than the minimum shot-to-edge distance. The measurement for shot-to-edge distance shall be taken from the center of the projectile impact to the nearest edge of the ballistic material in the test item.

Note – Procedures for determining the edge of the test item should be specified in other standards or specifications.

3.1.4 For intended edge shots, the test threat shall impact the test item no further from the edge than the maximum shot-to-edge distance.

3.1.5 The test threat shall impact the test item no closer to a prior impact than the minimum shot-to-shot distance. The measurement for shot-to-shot distance shall be taken from the center of one projectile impact to the center of another. 

Note – When assessing whether a particular impact location meets the minimum shot-to-shot distance requirements, the shot-to-shot distances should be measured from that impact location to all prior impact locations.

3.2 When warmer rounds are necessary, a test threat shall be fired through the projectile firing system to determine the exact point of impact. Additional test threats shall be fired as required until the proper alignment and a stable velocity have been achieved.

4. **Mounting and Positioning of Soft Armor Test Items on a Clay Block**

4.1 The test item shall be positioned on a clay block such that the entire test item is supported. When the test item exceeds the size of the clay block, backing fixture extensions shall be installed coplanar with the backing material surface to allow the test item to be fully supported.

4.1.1 Appliques needed for testing nonplanar soft armor test items shall be specified in other standards and specifications as necessary. 

4.2 The test item shall be held in contact with the clay block (and appliques if present) and secured using approximately 51 to 76 mm (2 to 3 in) wide elastic straps, held closed by hook-and-loop fasteners. Two vertical and three horizontal straps shall be positioned such that they do not interfere with the impact points on the test item. Figure I1 shows examples of strapping arrangements. 
Figure I1. Examples of Strapping Arrangements

4.3 The clay block shall be positioned to achieve proper bullet impact location and angle (for example, angle of incidence, obliquity) of the test threat. For any shots requiring a nonzero angle of incidence, the clay block shall be rotated to achieve the appropriate angle.

4.4 Between test threat impacts, the test item shall be manipulated by hand so that any wrinkles or bunching in the test item (caused by a previous shot) are smoothed out. 

4.4.1 No effort shall be made to recover any bullets trapped in the test item until the test series is complete.

**Note:** Slight manipulation of a bullet is allowed if the bullet will interfere with subsequent shots. 

4.4.2 The test item shall be repositioned on the backing material such that the test item is supported by smooth backing material for a distance of no less than 3 in (76 mm) in all directions around the next shot location.

4.4.3 Instructions related to striking the backing material between shots shall be specified by other standards and specifications.

5. **Mounting and Positioning of Hard Armor Test Items on a Clay Block**

5.1 The test item shall be positioned on a clay block such that the entire test item is supported. 

5.2 Testing of nonplanar hard armor test items on a clay block requires the use of appliques between the test item and the clay block.****

**Note:** Testing of planar hard armor test items does not require the use of appliques. 

5.2.1 The applique shall conform to the wear face of the test item and create a planar surface for the test item to contact the surface of the clay block. 

**Note:** Practice E3068 specifies how to create appliques for nonplanar armor intended for females.

5.2.2 The applique shall be formed such that it completely fills the space between the test item and the clay block surface. The applique shall be the minimum thickness required to completely fill the space without preventing contact between the test item edges (or corners) and the surface of the clay block (for example, a multi-curve plate should have at least four points of contact between its edges and the surface of the clay block). See Figure I2 for an example of a test item with an applique installed.
Figure I2. Example of test item with applique installed

**Note:** A mold is necessary to create an appropriate applique sized for a specific test item, and it is possible that the hard armor could serve as the mold. Other standards and specifications may provide guidance for creating the mold and the applique, and for conditioning the applique prior to use. Some testing requires that the hard armor be tested with soft armor or a shoot pack (i.e., in conjunction with armor). In those cases, the hard armor shall be placed appropriately in contact with the soft armor or a shoot pack (placed on the front or inserted). 

5.2.3 The applique shall be placed in intimate contact with the clay block prior to testing, and a modicum of force shall be applied to hold the applique in position.

5.2.3.1 When necessary to further secure the applique to the clay block, hand form conditioned clay into a long, thin strip. Place the strip around portions of the perimeter of the applique at the interface with the clay block, and press the clay strip into the interface to ensure that the applique remains adhered to the clay block during testing.

5.2.3.2 Care is required to ensure that the shape of the applique is not significantly changed during affixing it to the clay block.

5.3 The test item shall be positioned on a clay block (with or without an applique installed, as appropriate) such that the entire test item is supported, as shown in Figure 12. 

5.4 The test item shall be held in contact with the clay block and secured using approximately 51 to 76 mm (2 to 3 in) wide elastic straps, held closed by hook-and-loop fasteners. Vertical and horizontal straps shall be positioned such that they do not interfere with the impact points on the test item. 

5.5 The clay block shall be positioned to achieve proper bullet impact location and angle of incidence of the test threat. For any shots requiring a nonzero angle of incidence, the clay block shall be rotated to achieve the appropriate angle.

5.6 Between test threat impacts, any soft armor backing shall be manipulated by hand so that any wrinkles or bunching in the test item (caused by a previous shot) are smoothed out. No effort shall be made to recover any bullets trapped in the test item until the test series is complete. 

**Note:** Slight manipulation of a bullet is allowed if the bullet will interfere with subsequent shots.

6. **Ballistic Limit Procedure**

6.1 Test procedure requirements

6.1.1 A complete test series for the ballistic limit consists of individual ballistic tests being conducted on a number of individual test items. The conditions that constitute the dividing line between a partial penetration and a complete penetration shall be specified in other standards and specifications.

6.1.2 The velocity of the first shot and subsequent velocity increments shall be specified in other standards and specifications. 

6.1.3 The angles of incidence for all shots shall be 0°. 

6.1.4 For every shot, verify that the shot was a fair hit (per Section 9 of this standard), taking the following steps:

6.1.4.1 The difference between the velocity readings from each independent instrument shall be compared as specified in ASTM Specification E3062.

6.1.4.2 The shot spacing shall be assessed to determine if shot-to-edge, shot-to-shot, and shot-to-clay block edge distances meet specified requirements.

6.1.4.3 If the shot is determined to be unfair, another shot shall be taken on that test item in a location that meets shot spacing requirements. If there is not sufficient room to take an additional shot, then other standards or specifications shall specify the appropriate course of action.

6.2 Steps

6.2.1 Mount the test item on a clay block as described in either Section 4 or Section 5 of this annex (as appropriate).

6.2.2 Fire the first test threat at the test item.

6.2.3 When the first shot results in a complete penetration, subsequent shots shall be taken in accordance with the flowchart in Figure 13.

6.2.4 When the first shot results in a partial penetration, subsequent shots shall be taken in accordance with the flowchart in Figure 14.

6.2.5 Repeat the above steps until either the required number of shots or the maximum number of shots that can be placed on the test item has been reached. For a test item of size that does not allow the required number of shots, the firing sequence shall be continued on additional test items until the required number of shots is reached. The number of shots required depends on the protection capability claimed for the test item, and unless specified elsewhere, the requirements in Table 11 shall be followed.

6.2.6 After each sequence of required shots, a new sequence shall be performed until the total required number of shots for the test series has been reached.

6.2.7 When the ballistic limit is sufficiently high that achieving the velocity necessary to perforate the test item is difficult or impossible, the test laboratory shall document this situation has occurred. 

6.2.7.1 In such cases, the test series will be considered acceptable even if the minimum number of complete penetrations is not achieved, unless specified elsewhere.
