Full title and description

STB DIN EN 13565-2 2020-03 — Fixed firefighting systems — Foam systems — Part 2: Design, construction and maintenance. This is the German adoption of EN 13565-2:2018 including Amendment AC:2019, published by Deutsches Institut für Normung (DIN) and corrected by a subsequent corrigendum.

Abstract

DIN EN 13565-2 specifies requirements, design principles, installation criteria, testing, commissioning, inspection and maintenance procedures for fixed low-, medium- and high-expansion foam fire‑fighting systems used to control and extinguish fires involving flammable liquids. It complements component-level requirements in Part 1 of the series and references relevant foam concentrate standards.

Scope

This part of EN 13565 applies to the design, construction, installation, testing/commissioning and maintenance of fixed foam fire‑fighting systems intended for application to flammable liquid fires. It covers system types (low, medium and high expansion), layout and siting of foam equipment, hydraulic and proportioning arrangements, foam delivery devices (generators, branchpipes, chambers), storage and handling provisions for concentrates, acceptance testing and routine inspection/maintenance requirements. The standard is intended for use by system designers, manufacturers, installers and authorities having jurisdiction.

Key topics and requirements

• Design principles for low-, medium- and high-expansion foam systems, including application rates and coverage criteria.
• Specification of system components and materials suitable for foam concentrates and resistance to corrosion/contamination.
• Hydraulic calculations and pump/proportioner sizing, plus acceptable proportioning methods.
• Requirements for foam generators, branchpipes, foam chambers and discharge devices.
• Installation rules: pipework, fittings, storage tanks for concentrates, alarms and control arrangements.
• Commissioning and acceptance testing procedures, including performance verification and documentation.
• Inspection, periodic testing and maintenance schedules to ensure long‑term reliability.
• Compatibility and referencing of foam concentrate standards (EN 1568 series) and component tests (see Part 1).
• Marking, technical documentation and information to be supplied by manufacturers and system installers.

Typical use and users

Used by fire protection engineers, system designers, manufacturers of foam system components, installation contractors, building owners/operators of high-risk facilities (fuel storage, chemical plants, airports, tank farms), testing laboratories and authorities having jurisdiction (AHJs) for specifying, installing and maintaining fixed foam firefighting systems.

Related standards

FAQ

Q: What is this standard?

A: DIN EN 13565-2:2020-03 is the German adoption of EN 13565-2 (Part 2 of the Fixed firefighting systems — Foam systems series) that sets out design, construction, installation, testing and maintenance requirements for fixed foam fire‑fighting systems.

Q: What does it cover?

A: It covers system-level requirements for low, medium and high expansion foam systems: layout and siting, hydraulic design, proportioning arrangements, foam discharge devices, storage and handling of concentrates, commissioning and routine inspection/maintenance. It does not duplicate component test methods which are given in Part 1.

Q: Who typically uses it?

A: Fire protection designers, system manufacturers and suppliers, installers, testing laboratories, facility operators for high-risk sites (e.g., tank farms, terminals, airports, chemical plants), and regulatory/approval authorities use the standard to specify and verify foam systems.

Q: Is it current or superseded?

A: The DIN EN 13565-2:2020-03 edition is the current national implementation of EN 13565-2:2018 with Amendment 2019. The 2020 DIN publication replaced an earlier 2018 national edition and was corrected by a published corrigendum in July 2021. Users should check with their national standards body for any later amendments or replacements.

Q: Is it part of a series?

A: Yes — EN 13565 is a multipart series: Part 1 covers requirements and test methods for components; Part 2 covers design, construction and maintenance of complete systems. The series should be used together when specifying and verifying foam firefighting installations.

Q: What are the key keywords?

A: foam systems, fixed firefighting systems, design, installation, maintenance, foam generators, proportioners, branchpipes, EN 13565-2, DIN, foam concentrates (EN 1568).
