Definitions and Terminology Related to the field of Ballistic Testing
This page provides information about the Definitions and Terminology Related to the field of Ballistic Testing.

Weapon Systems
Most of the International Ballistic Testing Standards were developed based upon the range of common calibers available throughout the military and commercial sectors. The standards define the bullet types and projectile velocity ranges which Ballistic Resistant products must defeat. With regards to Small Arms Ballistic Test Standards requirements, the weapons listed here are the most common type military and commercial weapons utilized in the international community today. Other common “middle range” calibers which are not defined within a specification, such as the 7.62x39mm, can be defeated by a 7.62x51 NATO Ballistic Standard product.

Ballistic Standards
This section provides information on the 13 most common International Small Arms Ballistic Standards utilized today. It also informs you about CFR’s in-house Design-To Ballistic Standards.

Ballistic Standards Threat Comparison Relationship Charts
The Ballistic Standards Threat Comparison outlined in this section is to provide you with a better understanding on how all 11 International Ballistic Testing Standards compare side to side with each other with respect to the number of shots required. Both the Brunswick V50 and the Military MIL-SAMIT (25 shots) Standards were left out of the comparison because they are not similar to the other Ballistic Test Standards.

Close Focus Research (CFR) "Design-To" Ballistic Standards
Close Focus Research has developed two “Design-to” Ballistic Standards.

   (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

Refer to this section for information on how these Standards were derived.

Security Glazings and Bullet Proof Windows
Ballistic Resistance Capabilities of Transparent Security Glazings
The charts provided are to give you an idea of how thick Composite Transparent Security Glazings (Bullet Proof Windows) have to be in order to defeat the variety of ballistic threats indicated below.

Keep in mind that we can help you design thinner composite laminates to defeat a particular ballistic threat you require. Refer to the Ballistic Standards section for more details.

Maximum Altitude For Bullets Fired Vertically
The following page contains both a table of data and a chart illustrating the Maximum Altitude obtained for bullets when fired vertically.
