What is UL 758?

UL 758 is a standard published by Underwriters Laboratories (UL) that outlines the testing procedures for evaluating the bullet resistance of various materials, laminates, and glass products. The purpose of UL 758 is to establish standardized testing methods and performance criteria for ensuring the adequate protection of these materials against firearms used by criminals or attackers.

Testing Procedures

UL 758 specifies the procedures for testing the bullet resistance of various materials, including requirements for the materials to be tested, the type of bullet used, and the testing equipment. The standard covers various types of materials, such as glass, plastic, and metal, and provides guidelines for testing procedures to ensure that the materials provide adequate protection.

The standard also specifies the different levels of protection that materials can provide against various types of bullets, such as handgun and shotgun bullets. These levels are based on the stopping power of the bullet, which is the force required to stop the bullet from passing through the material.

UL 758 also includes requirements for the testing equipment, including the type of equipment that can be used for testing and the accuracy of the results. The standard also specifies the procedures for verifying the results of the testing to ensure that the materials provide adequate protection.

Impact and Resistance

UL 758 is based on the impact and resistance testing procedure, which involves simulating the impact of a bullet on the material and verifying that the material does not break or deform. The standard specifies the procedures for testing different types of materials, including the type of bullet used, the velocity of the bullet, and the thickness of the material.

The standard also specifies the requirements for the testing equipment, including the type of equipment that can be used for testing and the accuracy of the results. The standard also specifies the procedures for verifying the results of the testing to ensure that the materials provide adequate protection.

Conclusion

UL 758 is a technical standard published by UL that outlines the procedures for evaluating the bullet resistance of various materials, including glass, plastic, and metal. The purpose of UL 758 is to establish standardized testing methods and performance criteria for ensuring the adequate protection of these materials against firearms used by criminals or attackers. The standard specifies the procedures for testing different types of materials, including the type of bullet used, the velocity of the bullet, and the thickness of the material, and also specifies the requirements for the testing equipment.
