prBAS EN 13565-1+A1:2026

The requirements of this document set out the materials, construction, and performance of components intended for use in fixed foam fire fighting systems, and using foam concentrates conforming to EN 1568-1 to EN 1568-4. The components covered are: proportioners, sprayers, semi-subsurface hose units, branchpipes, low/medium expansion foam generators, high expansion foam generators, foam chambers, tanks and pressure vessels. Methods of test are given in Annex A to Annex K. Requirements are also given for the provision of the characteristic data needed for correct application of components. NOTE 1 Unless otherwise stated pressures are gauge pressures expressed in bar. The requirements of this document do not cover, except where stated, the use of combinations of components to form part, or the whole, of a fire fighting system. NOTE 2 Components conforming to this document are not necessarily compatible one with another. Requirements for pumps, motors and the functioning of mechanical components (i.e. remote control turrets) are outside the scope of this document.
