Close Focus Research (CFR) “Design-To” Ballistic Standards

The following two CFR “Design-To” Ballistic Standards are maximum threshold guidelines.

A product which meets or exceeds the CFR “Design-To” Ballistic Standards will pass all 10 International Ballistic Specifications.”

     (1) Close Focus Research (CFR) “Pass All” Ballistic Standard - CFR-PA-01 through CFR-PA-14

     (2) Close Focus Research (CFR) “SYA” Ballistic Standard - CFR-SYA-01 through CFR-SYA-14

Note: These “Design-To” standards are not official Ballistic Testing Standards, but instead, are design threshold guidelines for use in the development of Ballistic Resistant products.

Introduction
If you are familiar with all 12 of the International Small Arms Ballistic Standards, you can see that most of them are basically the same with the exception of the MIL-SAMIT Military Standard and the Brunswick V50 Standard. The main difference between the these standards are the bullet types, velocity ranges, and witness plates used to determine the spall characteristics of the test sample. In our experience we have found that problems can occur if a product was designed for a particular standard and later on in time needs to be re-qualified to another similar standard.

For example, if an armored window was designed to meet the National Institute of Justice NIJ Level III standard, it would most likely fail the Underwriters Laboratory UL 752 Level 8 standard because the UL 752 Level 8 standard is slightly more severe than the NIJ Level III standard. See the following standard comparison:

   National Institute of Justice NIJ Level III standard:
     • 7.62 NATO;   velocity / pattern parameters = 2,700 to 2,800 ft/sec;  5 shots >2 inch spacing

   Underwriters Laboratory UL 752 Level 8 standard:
     • 7.62 NATO;   velocity / pattern parameters = 2,750 to 3,025 ft/sec ; 5 shots in a 4.5 inch square

Also, the NIJ standard calls for a 0.020 inch type 2024-T3 or T4 Aluminum foil alloy witness plate and the UL 752 standard calls for a 0.125 inch thick corrugated cardboard witness plate to measure the spall characteristics.

This problem also arises with other caliber specifications within these International Small Arms Ballistic Standards.

To solve this problem, we at Close focus Research have developed two new “Design-To” Ballistic Standards. The first standard, called the CFR Pass All Ballistic Standard, is a standard based on the “Most Severe Specifications” found within the 10 International Small Arms Ballistic Standards. A product which can pass this “Pass All” Ballistic Standard will also pass all 10 International Small Arms Ballistic Standards. The second standard, called the CFR SYA Ballistic Standard is a standard based on a real world condition that an assailant could try to penetrate an armored product using a fully automatic or semi-automatic weapon by shooting it multiple time within the same area. A product which can pass this CFR SYA Ballistic Standard will definitely pass all 10 International Small Arms Ballistic Standards with a huge margin of safety.

To help you understand how we derived these two new Close Focus Research Ballistic Standards, refer to the last table and the associated chart on this page labeled “Most Severe Ballistic Specifications within the 10 International Small Arms Ballistic Standards”.

 

 

Close Focus Research (CFR) “Pass All” Ballistic Standard
A product that can pass this “Pass All” Ballistic Standard will also pass all 10 International Small Arms Ballistic Standards for each threat category defined below. This CFR Ballistic Standard was developed based on the “Most Severe Specifications” found within the 10 International Small Arms Ballistic Standards.

Close Focus Research (CFR) “SYA” Ballistic Standard
This CFR SYA Ballistic Standard is the most severe Small Arms Ballistic Standard. It is very similar to the “CFR Pass All” standard except that the number of shots have been increased to 16, the shot spacing has been reduced to 2.0 inches, and the Shot Pattern is over a 6 inch square . We at CFR developed this standard based on a real world condition that an assailant could try to penetrate an armored product using a fully automatic or semi-automatic weapon by shooting it multiple time within the same area.

In a typical situation where an assailant would attempt to defeat an armored product by shooting multiple times within the same area staring with a full 20 or 30 round magazine at a distance of 20 feet, the average impact shot density would be about 10 to 16 shots within a 6 inch square area. Using the upper limit of 16 shots impacting within this 6 inch square area, this would results in an average bullet spacing of approximately 2 inches. Keep in mind if the weapon was fired fully automatic, the shot density will be significantly less, meaning greater bullet spacing. If the assailant took his time and the weapon was fired semi-automatically, then the shot density could be higher, meaning a smaller bullet spacing.

 To summarize, the SYA Ballistic Standard was developed based on a situation where an assailant would fire 20 to 30 rounds at rate of 1 to 15 rounds / second from 20 feet. The resulting average impact shot density would be 10 to 16 shots within a 6 x 6 inch area. Based in these results, the SYA Ballistic Standard is defined using the upper limit of 16 shots within a 6 inch square area.

Since most pistols are limited to 15 rounds per magazine; most revolvers are limited to 6 or 7 rounds; and most assault rifles are limited to 20 to 30 rounds per magazine, then a Ballistic Resistant product designed to pass this SYA Ballistic Standard would defeat most rapid fire mode situations.

By the way, if a Ballistic Resistant product was designed to pass this SYA standard, it will definitely pass all 10 International Small Arms Ballistic Standards with a good margin of safety.

CFR Pass All Standards compared to the Most Severe Ballistic Specifications Standards
The following chart illustrates the CFR Pass All “Design-To” Standards compared to the Most Severe Ballistic Specifications within the 10 International Small Arms Ballistic Standards. Keep in mind that the CFR Standards call for 5 shots per test sample while all the other Standards call for 1, 2, 3, and 5 shots per test sample.
