Notes from the plant
Ballistic fabric, explained
Short technical notes on how ballistic fabric works and how to read a spec sheet, written from our own published data.
How does layer count affect ballistic protection?
Buyers reading a soft armor spec sheet usually ask two things first: how many layers, and what areal density. Here is how those two numbers relate to protection level, using our own SB160 and SB130 data.
What NIJ 0101.06 actually measures
The standard buyers name most often, and the one most often described loosely. What it covers, what Level IIIA means, and why we say tested to it rather than certified by it.
GJB4300A-2012 and why fragment testing is a separate question
Military programmes ask about fragments before handgun rounds. This is the standard that question sits under, and V50 rather than a pass or fail level is the number it produces.
How to read a V50 figure, and what STANAG 2920 is for
V50 is the most frequently misread number in a fabric specification. It looks like a protection level and it is not one. How the figure is obtained and how to compare two of them fairly.
GA141-2010, the standard behind Chinese police vest tenders
Built around the rounds Chinese police actually issue, which is what makes it different from an American standard. Includes our SB160 report at room temperature and at 60 degrees C.
