What is UL297?

UL 297 (Underwriters Laboratories Standard 297) is a professional technical standard that specifies the safety requirements for burglary-resistant safes. This rigorous standard establishes guidelines for the construction, performance, and testing of these safes to ensure their resistance against various criminal attacks, including drilling, prying, and explosives.

Definition and Purpose

UL 297 sets forth the minimum requirements for burglary-resistant safes that are used by businesses, financial institutions, jewelry retailers, and individuals to protect valuable assets from theft. It aims to provide a high level of security by ensuring that the safes meet specific criteria in terms of design, material strength, and locking mechanisms.

Key Requirements

1. Construction Standards: UL 297 outlines the necessary specifications for the materials, thickness, and structural integrity of the safes. This includes provisions for reinforced doors, solid steel walls, and secure anchor points to prevent unauthorized access.

2. Locking Mechanisms: The standard covers the performance of different lock types, such as combination locks, key locks, and electronic locks. It requires these mechanisms to undergo rigorous testing, including manipulation resistance and lock-picking durability.

3. Drill Resistance: Safes must withstand attempts at drilling and other cutting techniques. UL 297 specifies the time duration and extent of exposure to drilling, as well as the use of specialized tools and equipment.

4. Impact and Explosive Resistance: In order to protect the contents from explosions or blunt force impact, this standard subjects safes to rigorous testing using various mechanical tools, explosives, and impacts of different intensities.

Testing and Certification

To comply with UL 297, manufacturers submit their safes for thorough testing by certified laboratories. These independent labs perform a series of tests based on the standard's requirements. Only safes that pass all criteria are granted UL 297 certification, allowing them to be labeled as burglary-resistant by industry standards.

It is important for consumers to recognize the UL 297 label when purchasing safes, as it provides assurance of the product's quality and reliability. The certification signifies that the safe has undergone rigorous testing and meets the necessary standards for safeguarding valuable assets against theft.
