BS EN 13565: Parts 1 & 2

BS EN 13565-1 & BS EN 13565-2 are internationally recognised European Standards regarding Fixed Firefighting Foam Systems.

The standard was introduced by the European Committee for Standardization (CEN) in 1998.
The current revision is BS EN 13565-1: 2019.
BS EN 13565-1: 2019 covers the requirements and test methods for components of fixed firefighting systems that use foam concentrates.
Section 5 of the standard refers to the accuracy of the foam system's proportioning components and stipulates that produced foam shall be "not less than the rated concentration" and "not more than 30% above the rated concentration or 1 percentage point above the rated concentration (whichever is less)."
For further information on produced foam testing, please see our Produced Foam Testing page.

The standard was introduced by the European Committee for Standardization (CEN) in 2004.
The current revision is BS EN 13565-2: 2018.
BS EN 13565-2: 2018 covers the design, construction and maintenance of fixed firefighting systems that use foam concentrates.
Section 11 of the standard refers to required annual inspections of foam systems, and stipulates that "a test of the proportioner and associated fittings" shall be done annually "the accuracy of the foam proportioning shall be in accordance with the tolerance given in EN 13565-1."
Section 11 also stipulates that the quality of stored foam concentrates shall be annually checked "by competent and trained foam laboratory personnel."
