CAN ULC-S508-02 (R2013) PDF Download

The CAN ULC-S508-02 (R2013) standard is a set of requirements that focus on the rating and fire testing of fire extinguishers. The standard applies to fire extinguishers designed to combat Class A, B, C, D, and K fires. It also includes tests for fire extinguishing agents used specifically for Class D fires.

The rating of an extinguisher is determined based on its fire-extinguishing potential, which is assessed through fire testing. It is important to note that the standard assumes that the extinguishers will be installed and used in accordance with the United States' Standard for Portable Fire Extinguishers, NFPA 10, and the National Fire Code of Canada.

Additionally, the standard explains that fire extinguishers, fire extinguishing agents, or both must also meet specific construction and performance requirements based on their type, design, size, and arrangement. The standard refers to several other related standards, such as ANSI/UL 8 CAN/ULC S554, ANSI/UL154 CAN/ULC S503, ANSI/UL299 CAN/ULC S504, ANSI/UL 626 CAN/ULC S507, and ANSI/UL2129 CAN/ULC S566, which outline additional requirements that are not covered within the CAN ULC-S508-02 (R2013) standard.
