30、This is the common UL and ULC Standard for Dry Chemical Fire Extinguishers. It is the third edition of CAN/ULC-S504, and the eleventh edition of UL 299. This common Standard was prepared by Underwriters Laboratories Inc., ULC Standards and the dry chemical re extinguisher manufacturing industry. (Th
31、e efforts and support of the Extinguisher Technical Harmonization Committee are gratefully acknowledged.) This Standard was formally approved by the ULC Committee on Portable Fire Extinguishers. The Annexes in this Standard are for information purposes only. Note: Although the intended primary appli
32、cation of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. Level of harmonization This standard used an ISO format, but is not based on, nor shall it be considered equi
33、valent to, an ISO standard. This standard is published as an identical 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 i
34、nterpretation by the SDO of an identical or equivalent standard shall 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
35、 as possible to each of the SDOs to more accurately reect the intent. UL Effective Date A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved Standard.

36、REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover the construction and performance, exclusive of performance during re tests, of portable dry chemical and dry powder (Class D) re extinguishers. Dry chemical and dry powder re extinguishers are i
37、ntended to be utilized in accordance with the Standard for Portable Fire Extinguishers, ANSI/NFPA 10 and with the National Fire Code of Canada. 1.2 The requirements for performance during re testing of dry chemical re extinguishers are specied in the Binational Standard for Rating and Fire Testing o
38、f Fire Extinguishers, ANSI/UL 711/CAN/ULC-S508. 1.3 As used in these requirements, the term extinguisher refers 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 un
39、it for purposes of this standard. Where values of measurement are specied in both SI and English units, either 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
40、 code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. When the latest edition of a standard is not applicable, the appropriate edition is indicated accordingly in Annex A. 4 Components 4.1 Except as indicate
41、d in 4.2, a component of a product covered by this standard shall comply with the requirements 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
42、with a specic requirement that: a) Involves a feature or characteristic not required in the application 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 int
43、ended conditions of use. 4.4 Specic components are incomplete in construction features or restricted 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 c
44、onditions. 5 Glossary 5.1 For the purpose of this standard, the following denitions apply.

45、guisher not capable of nor intended to undergo complete maintenance including internal inspection of cylinder, replacement of parts and seals and hydrostatic testing. 5.3 EFFECTIVE DISCHARGE The time of discharge of extinguishing agent from the extinguisher until gas point. 5.4 EXPELLANT GAS A compr
46、essed or pressurized gas used to propel the dry chemical extinguishing agent from a single cylinder. 5.5 GALVANIC COMPATIBILITY Fire extinguisher cylinder and component parts which are not susceptible to 10-day stress corrosion cracking nor corrosion from combination of dissimilar materials. 5.6 GAS
47、 POINT The point in time when the discharge changes from extinguishing agent to a gas and dry chemical combination. 5.6.1 HIGH FLOW EXTINGUISHER A dry chemical extinguisher with a minimum 4.54 kg (10.0 lb) of extinguishing agent, an agent ow rate of at least 0.454 kg/s (1.0 lb./s), and having attain
48、ed a Class B rating, suitable for Class B specic hazard applications specied in the National Fire Protection Association Standard for Portable Fire Extinguishers, NFPA 10. 5.7 PORTABLE FIRE EXTINGUISHER A re extinguisher carried or on wheels and operated by hand. 5.8 PRESSURE GAUGE A gauge that show
49、s the pressure in the cylinder and the operating range of the extinguisher based upon the operating temperature-pressure relationship in appropriate pressure units. 5.9 PRESSURE INDICATOR An indicator that shows that the extinguisher is pressurized with its rated expellant gas pressure. 5.10 RECHARGEABLE (REFILLABLE) FIRE EXTINGUISHER A re extinguisher capable of undergoing complete maintenance including internal inspection of cylinder, replacement of parts a
