This document specifies requirements and test methods for materials, construction and performance of components intended for use in powder firefighting systems complying with EN 12416-2:2001+A1:2007.
The components covered are as follows:
— powder containers
— expellant gas container assemblies
— pressure regulators and gauges
— actuators
— main isolating valves and selector valves
— nozzles.
The components are suitable for powder firefighting systems for general use in buildings and other construction works. In areas with a risk of explosion, earthquake zones, extreme environmental conditions e.g. marine, offshore, mining or aircraft additional considerations apply.
This document covers components for use in powder extinguishing systems complying with EN 12416-2:2001+A1:2007. It does not cover, for example, pipes and fittings which are covered by more general standards for which requirements and recommendations are given in EN 12416-2:2001+A1:2007. Nor does it cover fire detectors or electrical control and indicating equipment.

This part of EN 1366 specifies a test method for determining the fire resistance of smoke extraction ducts that are used for single compartment applications only. In such applications, the smoke extraction system is only intended to function up to flashover (typically 600 °C).
This method of test is only suitable for ducts constructed from non-combustible materials (euro class A1 and A2-s1, d0).
It is applicable only to four sided and circular ducts. One-, two- and three-sided ducts are not covered. This standard is applicable only for the standard sizes or smaller as described.
This test method of part 9 is applicable only to smoke extraction ducts that do not pass into other fire compartments. For smoke extraction ducts that pass into other compartments, the method of test described in EN 1366-8 is used.
The smoke extraction duct is part of the smoke extraction system which also includes smoke control dampers and smoke extract fans.

This document specifies a test method for determining the fire resistance of smoke extraction ducts. It is applicable only to smoke extraction ducts that pass through another fire compartment from the fire compartment to be extracted in case of fire. It represents fire exposure of a fully developed fire.
This method of test is only applicable to ventilation ducts with the following classification according to EN 13501-3:
— fire from inside and outside i ↔ o;
— applicable to a pressure difference up to 500 Pa;
NOTE 1 Requires that the duct A test(s) has been preformed with an under-pressure of minimum 500 Pa.
— with integrity (E) and insulation (I) criteria equal to or higher than the intended classification for the smoke extraction duct.
NOTE 2 According to: EN 13501–4:2009/A1:2009 Multi-compartment smoke extraction duct can only be classified as EI.
For the purposes of the test described in this document, the duct is referred to as duct C.
This test method has been designed to cover both vertical and horizontal smoke extraction ducts. A vertical system need not be evaluated to this method provided that:
— both horizontal (ho) and vertical (ve) classification according to EN 13501-3 has been obtained for the ventilation duct, and
— it has been tested in a horizontal orientation to this method.
If the ventilation duct in practice is only used for vertical applications in smoke extraction systems, only vertical (ve) classification is bound to be used and tested in a vertical orientation to this method according to EN 13501-3.
This test method is suitable for ducts constructed from non-combustible materials (Euroclass A1 and A2).
NOTE 3 Using combustible material could lead to an incorrect calculation of the leakage based on the oxygen measurement. E.g. galvanisation could lead to some negative effects for the measurements.
It is applicable only to four sided ducts; one, two and three sided ducts are not covered.

This document specifies product characteristics and test methods of open nozzles and automatic nozzles for use in water mist systems.

This document specifies the evaluation of the fire performance of water mist systems for non-stacking garages, fully enclosed garages and underground garages.
This document is applicable for horizontal, solid, flat ceilings with heights of 2 m and above.
