Scope

These requirements cover the construction and performance, exclusive of performance during fire tests, of portable halocarbon clean agent fire extinguishers. Halocarbon clean agent fire extinguishers are intended to be utilized in accordance with the Standard for Portable Fire Extinguishers, NFPA 10 and with the National Fire Code of Canada.

The requirements for performance during fire testing of halocarbon clean agent fire extinguishers are specified in the Binational Standard for Rating and Fire Testing of Fire Extinguishers, ANSI/UL 711/CAN/ULC-S508.

As used in these requirements, the term "fire extinguisher" refers to all extinguishers or any part thereof covered by these requirements, unless specifically noted otherwise.

Project Need
This proposal is intended to provide improved definition and clarity to salt spray corrosion testing required under ULC S566 and related portable extinguisher standards. It should not compromise the safety, functionality, or performance of an extinguisher. Unlike suppression systems, portables are subjected to repeated corrosion testing using randomly selected production samples. The intent of this testing is understandable. However, in practice, the requirement of zero defects is challenging at best in a manufacturing environment. Other corrosion standards, such as MIL-A-8625F, have taken a more pragmatic approach and permit a defined level of defects. Proposed changes include sample evaluation methods, decorative coatings/plating, aluminum components, porous surfaces/ imperfections and pre-approved components.
