Portable fire extinguishers - Part 8: Requirements for the construction, pressure resistance and mechanical tests for extinguishers with a maximum allowable pressure equal to or lower than 30 bar, which comply with the requirements of EN 3-7

This European Standard specifies the rules of design, type testing, fabrication and inspection control of portable fire extinguishers which comply with the requirements of EN 3 7; with metallic bodies as far as pressure risk is concerned.
This part of EN 3 applies to portable fire extinguishers of which the maximum allowable pressure PS is lower than or equal to 30 bar and containing non-explosive, non-flammable, non-toxic and non-oxidising fluids.
This European Standard also applies to the marking of metallic propellant gas cartridges (see Annex E).
This European Standard does not apply to carbon dioxide fire extinguishers.
NOTE   Annex A gives the classification of the different parts forming the portable fire extinguisher.

La présente Norme européenne définit les règles de conception, d'essais de type, de fabrication et d’inspection des extincteurs d’incendie portatifs conformes aux exigences de l'EN 3-7 dont le corps est en métal, en ce qui concerne les risques liés à la pression.
La présente partie de l'EN 3 s'applique aux extincteurs d’incendie portatifs dont la pression maximale admissible PS est inférieure ou égale à 30 bar et qui contiennent des fluides inexplosibles, ininflammables, non toxiques et non oxydants.
La présente Norme européenne s'applique également au marquage des cartouches de gaz métalliques (voir Annexe E).
La présente Norme européenne ne s'applique pas aux extincteurs à dioxyde de carbone.
NOTE   L'Annexe A donne la classification des différentes parties constitutives d'un extincteur portatif.

Foreword
This document (prEN 3-8:2013) has been prepared by Technical Committee CEN/TC 70 “Manual means of
fire fighting equipment”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 3-8:2006.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this
document.
This document is included in a series of European Standards planned to cover:
a) classification of fires (EN 2);
b) mobile fire extinguishers (series EN 1866).
EN 3 consists of the following parts, under the general title "Portable fire extinguishers":
 Part 7: Characteristics, performance requirements and test methods
 Part 8: Requirements for the construction; pressure resistance and mechanical tests for extinguishers
with a maximum allowable pressure equal to or less lower than 30 bar, which comply with the
requirements of EN 3-7
 Part 9: Requirements for the assembly, construction and pressure resistance of CO extinguishers which
comply with the requirements of EN 3-7
 Part 10: Provisions for evaluating the conformity of a portable fire extinguisher to EN 3-7
