line of the bolts.
— If an 'O' ring seal or ring gasket is used, the assumed area of pressure application extends out to

4.2.1 Removal
Parts intended for removal during routine field maintenance shall be accessible, removable, and
replaceable without damage using appropriate tools normally used by the trade, or special tools
recommended by the component manufacturer.

The design and construction of any part intended for removal during routine field maintenance
shall be such that it cannot be re-assembled so as to cause malfunction of the component, without
an external visible indication.
4.3 Hydrostatic strength

+1
hydrostatic pressure of 1,5 times the working pressure specified by the manufacturer bar, when
tested in accordance with Annex A.

b) any corrosion resistant coating (such as paint) shall remain intact and shall adhere to the
surface so as not to be removable (when removal exposes a material subject to corrosion) by
such action as washing or rubbing with a fingernail;
c) dissimilar metals in contact or close proximity with one another shall show no signs of galvanic
corrosion;

b) shall show no signs of cracking when examined under 25 × magnification;
c) comply with the hydrostatic strength test under 4.3.1.
For large non-moving parts and non-pressure components the test may be carried out using

component the test piece shall be similarly cast and machined. Sub-assemblies of moving parts may
be tested.
4.5.3 Internal corrosion
Other than the exception below, those parts of components which are exposed to foam concentrate,

At the conclusion of the test, check that the mechanical operation of all working parts is unimpaired
and that there are no significant corrosion effects inside or outside. Significant corrosion defects are
pits, cracks and blisters.
The foam concentrate manufacturer should always be consulted on the suitability of containers and
their linings and external paint finish, valves, fittings and pipework, for long-term storage of
concentrate or solution.
This requirement does not apply to components that are exposed to the corrosive media (i.e. foam

SIST EN 13565-1:2019 표준은 고정 화재 진압 시스템의 폼 시스템에 대한 필수 요구사항 및 테스트 방법을 제시합니다. 이 표준의 범위는 EN 1568-1에서 EN 1568-4에 부합하는 폼 농축액을 사용하는 고정 폼 화재 진압 시스템에서 사용되는 구성 요소의 재료, 구조 및 성능 요구 사항을 포함합니다. 다루는 구성 요소로는 비율 조정기, 분무기, 반잠수형 호스 장치, 분기관, 저/중 고형화 폼 생성기, 고형화 폼 생성기, 폼 챔버, 탱크 및 압력 용기가 있습니다. 테스트 방법은 부록 A에서 K까지 상세히 명시되어 있습니다. 이 표준의 강점 중 하나는 고정 폼 화재 진압 시스템에 사용되는 여러 구성 요소의 특성을 명확히 정의하고 있어 이를 통해 사용자들이 올바른 구성 요소를 선택하고 사용할 수 있도록 돕는다는 점입니다. 또한, 각 구성 요소에 대한 필요한 특성 데이터의 제공에 대한 요구 사항을 명확하게 하고 있어 운영에서의 정확한 적용을 가능하게 합니다. SIST EN 13565-1:2019는 고정 화재 진압 시스템의 안전성과 효율성을 보장하기 위한 기준이 되어 현재 및 미래의 화재 진압 기술 발전에 저항력을 가질 수 있게 합니다. 이 표준은 화재 안전 및 예방 분야에서 매우 중요한 참고 자료로, 폼 시스템의 설계 및 운영에 있어 모두가 따라야 할 핵심적인 지침서를 제공합니다. 따라서 고정 폼 화재 진압 시스템을 구축하거나 유지보수하는 경우, SIST EN 13565-1:2019의 요구 사항을 준수하는 것이 필수적이며, 이는 시스템의 전반적인 신뢰성을 높이는데 큰 역할을 합니다.
SIST EN 13565-1:2019の標準は、固定式消火システムにおける泡システムのコンポーネントに関する要求事項と試験方法を規定しています。この標準は、EN 1568-1からEN 1568-4に準拠した泡濃縮剤を使用する固定式泡消火システムに必要な材料、構造、性能を明確に定義しており、その範囲は非常に広範です。 この文書における強みは、泡システムを構成する様々なコンポーネント（比例器、スプレイヤー、半埋設ホースユニット、分岐管、低/中圧泡発生器、高圧泡発生器、泡チャンバー、タンク、圧力容器など）の要件を詳細に扱っている点です。また、これらのコンポーネントの適切な使用に必要な特性データを提供する要求事項が含まれているため、実務者が選定を行いやすくなっています。 さらに、付属書Aから付属書Kにかけて、試験方法が規定されているため、各コンポーネントの性能を確実に確認できることも重要なポイントです。この標準では、圧力はバールで表示される圧力計の値を基準にすることが示されており、実際の運用における明確な指標となります。 一方で、この文書は消火システム全体や異なるコンポーネントの組み合わせに関する要求事項をカバーしていないため、システム全体の設計に関しては他の基準との併用が必要です。また、ポンプやモーター、機械的コンポーネントの機能ように、他の側面はこの文書の適用外であるため、ユーザーはそれらについても考慮する必要があります。 総じて、SIST EN 13565-1:2019は、固定式泡消火システムに必要な主要な要求事項を明確に示しており、業界のニーズに応えるために設計された非常に関連性の高い標準であると言えます。
The EN 13565-1:2019 standard provides comprehensive requirements for components employed in fixed firefighting systems that utilize foam fire-fighting techniques. This document is critical for ensuring that materials and constructions meet specified performance levels, thereby enhancing the effectiveness and safety of foam firefighting systems. Its scope includes a diverse range of components such as proportioners, sprayers, semi-subsurface hose units, branchpipes, foam generators, foam chambers, tanks, and pressure vessels. By clearly delineating these components, the standard helps builders, designers, and safety engineers select appropriate elements for their specific applications, aligning with foam concentrates conforming to EN 1568-1 to EN 1568-4. One of the strengths of this standard lies in its detailed methodology for testing components, as outlined in Annex A to Annex K. These tests provide empirical data on the performance and reliability of the components, ensuring that they can be subjected to real-life conditions encountered during firefighting operations. The emphasis on standardized test methods significantly enhances the trustworthiness of component performance claims, making it easier for users to compare prospective options in the market. Another critical aspect of the EN 13565-1:2019 standard is the requirement for characteristic data provision. This ensures that all relevant data needed for the proper application of components is readily available. Such transparency aids in the safe and efficient use of foam systems in firefighting scenarios, enhancing both responsible equipment selection and the potential for successful fire suppression outcomes. Furthermore, the standard acknowledges limitations regarding component integration, emphasizing that components conforming to this document may not necessarily be compatible with one another. This clarity prevents engineering oversights during system design and installation, promoting more efficient project planning and execution. While this standard is robust in its coverage of foam firefighting components, it does not extend to pumps, motors, or mechanical components such as remote control turrets. This focus allows for heightened specialization in foam system components, without diluting the standard’s efficacy by encompassing unrelated entities. Overall, EN 13565-1:2019 stands as a pivotal document in the realm of fixed firefighting systems, offering crucial guidelines that ensure both the quality and functionality of foam components, thereby reinforcing the safety and reliability of fire suppression efforts.
