Foreword
This document (prEN 1866-3:2006) 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 1866:2005.
This standard EN 1866 consists of the following parts under the general title "Mobile fire extinguishers":
 Part 1: Characteristics, performance requirements and test methods
 Part 2: Additional requirements to EN 1866-1 for the construction, resistance to pressure and mechanical
tests for extinguishers with a maximum allowable pressure equal to or lower than 30 bar
 Part 3: Additional requirements to EN 1866-1 for pressure resistance of CO extinguishers
