It is the Seconded
32、ition of CAN/ULC-S554, and the Sixth edition of ANSI/UL 8.This harmonized Standard was prepared by Underwriters Laboratories Inc., ULC Standards and theExtinguisher Technical Harmonization Committee.This Standard was formally approved by the ULC Committee on Portable Fire Extinguishers.Level of harm
33、onizationThis standard used an ISO format, but is not based on, nor shall it be considered equivalent to, an ISOstandard. This standard is published as an identical standard.An identical standard is a standard that is the same in technical content except for conflicts in Codes andGovernmental Regula

These fire extinguishers are intended to be utilizedin accordance with the Standard for Portable Fir
38、e Extinguishers, NFPA 10 and with the National Fire Codeof Canada.1.2 The requirements for performance during fire testing of water based agent fire extinguishers arespecified in the Binational Standard for Rating and Fire Testing of Fire Extinguishers, ANSI/UL 711CAN/ULC-S508.1.3 As used in these r
39、equirements, the term extinguisher refers to all extinguishers or any part thereofcovered by these requirements, unless specifically noted otherwise.2 Units of Measurement2.1 The metric unit shall be designated as the official unit for purposes of this standard. Where values ofmeasurement are specif
40、ied in both SI and English units, either unit is used. In cases of dispute, the metricunit shall be used.3 Reference Publications3.1 See Annex A for a list of publications referenced in this standard. Any undated reference to a codeor standard appearing in the requirements of this standard shall be
41、interpreted as referring to the latestedition of that code or standard. When the latest edition of a standard is not the applicable standard, theappropriate edition is indicated accordingly in Annex A.4 Components4.1 Except as indicated in 4.2, a component of a product covered by this standard shall
42、 comply with therequirements for that component. A component shall comply with both the Underwriters Laboratories Inc.and the Underwriters Laboratories of Canada standards for the component.4.2 A component is not required to comply with a specific requirement that:a) Involves a feature or characteri
43、stic not required in the application of the component in theproduct covered by this standard, orb) Is superseded by a requirement in this standard.4.3 A component shall be used in accordance with its rating established for the intended conditions ofuse.4.4 Specific components are incomplete in const
44、ruction features or restricted in performance capabilities.Such components are intended for use only under limited conditions, such as certain temperatures notexceeding specified limits, and shall be used only under those specific conditions.5 Glossary5.1 For the purpose of this standard, the follow
