Police Bullet Proof Vest- The Basic Things that You Must Know

Some individuals are not really familiar with the police bulletproof vest. Of course, as they watch it from the movies and TV programs, they already know that it is used for protecting one’s self. But, when it comes to its construction and other things, they do not know that much. To help them get to know the police bullet proof vest, here are the basic information about this ballistic vest.

Materials for Construction

A police bullet proof vest is made up of strong and flexible synthetic fibers. The most commonly used materials are the Spectra and the Kevlar. However, more and more fibers are discovered throughout the years. Other fibers that are used include Dyneema, and Goldflex. A police bullet proof vest is composed of several layers of these fibers in order to produce a strong and flexible bullet proof vest.

Ratings and Classifications

Not all bullet proof vests are the same. They are classified by the National Institute of Justice according to the protection level that they provide for the user. The common ratings or classifications for a police bullet proof vest are Type I, Type II, Type II-A, Type III, Type IIIA, and Type IV. The higher the rating is, the higher the protection that the police bullet proof vest can provide. But also, the higher the rating is, the heavier the ballistic vest.

Testing and Quality Control

After the police bullet proof vest is designed and created by the manufacturer, they are required to pass it to the National Institute of Justice for checking and quality control. The NIJ makes sure that the bullet proof vest meets their standard for safety and protection. If the ballistic vest did not pass the standard of the NIJ, the NIJ requires the manufacturer to redo it again until the desired requirements are met. A police bullet proof vest that is approved by the NIJ has a mark on its inner side.
