This European Standard has the general title "Fixed firefighting systems - Powder systems" and consists of the following two parts:
Part 1 : Requirements and test methods for components Part 2 : Design, construction and maintenance
Annex A to annex N are normative annexes.
This European Standard is included in a series of European Standards planned to cover also:
a) gas extinguishing systems (EN 12094); b) sprinkler systems (EN 12259 and EN 12845); c) smoke control systems (EN 12101); d) explosion protection systems (EN 26184); e) foam systems (EN 13565); #f) hose systems (EN 671); g) water spray systems (EN 14816).$
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
Introduction
It has been assumed in the preparation of this standard that the execution of its provisions is entrusted to appropriately qualified and experienced people.

Scope
This European Standard specifies requirements and test methods for materials, construction and performance of components intended for use in powder firefighting systems complying with prEN 12416-2:2000.
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 standard covers components for use in powder extinguishing systems complying with prEN 12416-2:2000. It does not cover, for example, pipes and fittings which are covered by more general standards for which requirements and recommendations are given in prEN 12416-2:2000. Nor does it cover fire detectors or electrical control and indicating equipment.
Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited in the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications, apply to this European standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
