CAN ULC-S321-1991 (R2016) PDF Download

CAN ULC-S321-1991 (R2016) is a Canadian national standard that outlines the requirements for burglary resistant vault doors and modular panels. The purpose of this standard is to ensure that these doors and panels used in financial institutions, commercial properties, and other establishments are able to effectively protect the contents of enclosed spaces from burglary attacks. The standard does not cover requirements for fire resistant ratings, as those are determined by other regulations.

The main focus of this standard is to establish the burglary resistant rating of vault doors and modular panels. The rating is determined by the amount of time the doors and panels can withstand attacks from common mechanical and electrical tools, cutting torches, or any combination of these means. The standard aims to provide guidance for manufacturers, contractors, and stakeholders in the industry to ensure that the products they produce or install meet the necessary security requirements.
