CAN ULC-S504-12 PDF Download

The CAN ULC-S504-12 standard is a common standard for Dry Chemical Fire Extinguishers. It is the third edition of the Canadian ULC Standard and the eleventh edition of the UL Standard. This standard specifically focuses on the construction and performance of portable dry chemical and dry powder (Class D) fire extinguishers, excluding their performance during fire tests.

The dry chemical and dry powder fire extinguishers covered by this standard are designed to be used in compliance with the Standard for Portable Fire Extinguishers, ANSI/NFPA 10, as well as the National Fire Code of Canada. These requirements ensure that the fire extinguishers are constructed and perform effectively in extinguishing fires.

It is important to note that the performance of dry chemical fire extinguishers during fire tests is governed by the Binational Standard for Rating and Fire Testing of Fire Extinguishers, ANSI/UL 711/CAN/ULC-S508. This indicates that the testing and rating criteria for these extinguishers are covered by a separate standard.
