Scope:

These requirements cover rating, and performance during fire tests, of fire extinguishers intended for use in attacking Class A, B, C, D, and K fires as defined herein. These requirements also cover performance during fire tests of fire extinguishing agents for application on Class D fires. The ultimate rating of an extinguisher or the prescribed use of an extinguisher or fire extinguishing agent is based on its fire-extinguishing potential as determined by fire tests and presupposes installation and use in accordance in the United States with the Standard for Portable Fire Extinguishers, NFPA 10, and with the National Fire Code of Canada.

Fire extinguishers, fire extinguishing agents, or both shall also comply with the requirements for construction and performance as applicable to specific types, designs, sizes, and arrangements. Such additional requirements include 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 and are not within the scope of these requirements.

Project need:

ULC proposes a revision to Clause 8.1.4 of ULC-S08. This proposed change to ULC-S508 eliminates a dangerous scenario for test personnel and a fire test of limited value by allowing dry chemical portable extinguishers intended for a rating greater than 20-B to proceed directly to the intended outdoor test fire. Also, ULC proposes removing the Class A panel fire tests, Section 7.3.
