29、PERMISSION FROM UL Preface This is the harmonized UL and ULC Standard for Water Based Agent Fire Extinguishers. It is the Third edition of CAN/ULC-S554, and the Seventh edition of ANSI/UL 8. This harmonized Standard was prepared by Underwriters Laboratories Inc., ULC Standards and the Extinguisher T
30、echnical Harmonization Committee. This Standard was formally approved by the ULC Committee on Portable Fire Extinguishers. Level of harmonization This standard used an ISO format, but is not based on, nor shall it be considered equivalent to, an ISO standard. This standard is published as an identic
31、al standard. An identical standard is a standard that is the same in technical content except for conicts in Codes and Governmental Regulations. Presentation shall be word for word except for editorial changes. Interpretations The interpretation by the SDO of an identical or equivalent standard shal
32、l be based on the literal text to determine compliance with the standard in accordance with the procedural rules of the SDO. If more than one interpretation of the literal text has been identied, a revision shall be proposed as soon as possible to each of the SDOs to more accurately reect the intent
33、. UL Effective Date A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved Standard.

34、N 1 Scope 1.1 These requirements cover the construction and performance, exclusive of performance during re tests, of portable water based agent re extinguishers. These re extinguishers are intended to be utilized in accordance with the Standard for Portable Fire Extinguishers, NFPA 10 and with the
35、National Fire Code of Canada. 1.2 The requirements for performance during re testing of water based agent re extinguishers are specied in the Binational Standard for Rating and Fire Testing of Fire Extinguishers, ANSI/UL 711 CAN/ULC-S508. 1.3 As used in these requirements, the term extinguisher refe
36、rs to all extinguishers or any part thereof covered by these requirements, unless specically noted otherwise. 2 Units of Measurement 2.1 The metric unit shall be designated as the official unit for purposes of this standard. Where values of measurement are specied in both SI and English units, eithe
37、r unit is used. In cases of dispute, the metric unit shall be used. 3 Reference Publications 3.1 See Annex A for a list of publications referenced in this standard. Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the lat
38、est edition of that code or standard. When the latest edition of a standard is not the applicable standard, the appropriate edition is indicated accordingly in Annex A. 4 Components 4.1 Except as indicated in 4.2, a component of a product covered by this standard shall comply with the requirements f
39、or 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 specic requirement that: a) Involves a feature or characteristic not required in the appl
40、ication of the component in the product covered by this standard, or b) 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 of use. 4.4 Specic components are incomplete in construction features or restri
41、cted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 5 Glossary 5.1 For the purpose of this standard, the following denitions apply.

43、of the agent concentrate with water. 5.4 CARTRIDGE OPERATED EXTINGUISHER A re extinguisher in which the extinguishing agent and expellant gas are in separate cylinders. 5.5 DISPOSABLE (NONRECHARGEABLE) FIRE EXTINGUISHER A re extinguisher not capable of nor intended to undergo complete maintenance in
44、cluding internal inspection of cylinder, replacement of parts and seals and hydrostatic testing. 5.6 EFFECTIVE DISCHARGE The time of discharge of extinguishing agent from the extinguisher until gas point. 5.7 EXPELLANT GAS A compressed or pressurized gas used to propel the extinguishing agent from a
45、 single cylinder. 5.8 EXTINGUISHER, DRY CHARGE TYPE An extinguisher in which the foam concentrate or additive concentrate is not mixed with the water until the extinguisher is activated. The water is stored in the extinguisher cylinder, and the concentrate is stored in a separate part of the extingu
46、isher. 5.9 EXTINGUISHER, LIQUID CHARGE TYPE An extinguisher in which a mixture of the foam concentrate or additive concentrate and water is stored in the extinguisher cylinder. 5.10 GALVANIC COMPATIBILITY Fire extinguisher cylinder and component parts which are not susceptible to 10-day stress corro
47、sion cracking, or corrosion from combination of dissimilar materials. 5.11 GAS POINT The point in time when the discharge changes from extinguishing agent to a gas and extinguishing agent combination. 5.12 PORTABLE FIRE EXTINGUISHER A re extinguisher carried or on wheels and operated by hand. 5.13 P
48、RESSURE GAUGE A gauge that shows the pressure in the cylinder and the operating range of the extinguisher based upon the operating temperature-pressure relationship in appropriate pressure units. 5.14 PRESSURE INDICATOR An indicator that shows that the extinguisher is pressurized with its rated expe
49、llant gas pressure. 5.15 RECHARGEABLE (REFILLABLE) FIRE EXTINGUISHER A re extinguisher capable of undergoing complete maintenance including internal inspection of cylinder, replacement of parts and seals and hydrostatic testing. 5.16 STORED PRESSURE TYPE FIRE EXTINGUISHER A re extinguisher in which both the extinguishing agent and expellant gas are in a single cylinder. 5.17 WATER BASED AGENT Water or water agent solution.
