La norme EN 12952-1:2015, intitulée "Chaudières à tubes d'eau et installations auxiliaires - Partie 1 : Général", présente un cadre essentiel pour les chaudières à tubes d'eau avec des volumes supérieurs à deux litres. Elle s'applique à la génération de vapeur et/ou d'eau chaude à des pressions maximales autorisées supérieures à 0,5 bar et à des températures supérieures à 110 °C, ainsi qu'aux installations auxiliaires. L'un des principaux points forts de cette norme réside dans son engagement à s'assurer que les exigences de sécurité fondamentales, conformément à l'Annexe I de la Directive sur les Équipements Sous Pression, sont satisfaites. Cela garantit non seulement la sécurité des chaudières à tubes d'eau, mais également celle des installations qui les accompagnent. Les méthodes de conception, de fabrication, d'essai et d'inspection, soigneusement définies, optimisent la sécurité et l'efficacité du système. En outre, la norme aborde les dangers liés à la pression, un aspect crucial dans le contexte des chaudières à tubes d'eau, notamment les risques associés à la défaillance des composants de retenue de pression due à la surchauffe. Grâce à l'intégration d'informations sur les dangers résiduels et les mesures de réduction des risques, cette norme s'avère particulièrement pertinente pour les fabricants et les exploitants. La définition claire de l'assemblage de la chaudière inclut non seulement la chaudière elle-même et ses composants sous pression, mais aussi les accessoires de sécurité, les échanges thermiques, ainsi que les systèmes de contrôle nécessaires. De plus, la norme prend en compte divers équipements auxiliaires, tels que les systèmes d'insufflation d'air et les installations de réduction de la pollution, garantissant ainsi une approche globale de la sécurité et de l'efficacité des équipements. La norme EN 12952-1:2015 s'affirme donc comme un outil précieux pour les professionnels du secteur, offrant une base solide pour la conception et l'exploitation sécurisées des chaudières à tubes d'eau et des installations auxiliaires. Sa portée et sa pertinence en font un référentiel incontournable dans le domaine des équipements sous pression.
The EN 12952-1:2015 standard provides a comprehensive framework for the design and safety of water-tube boilers and auxiliary installations, particularly those operating at high pressures and temperatures. Its scope is well-defined, applying specifically to water-tube boilers with a volume exceeding two liters, generating steam and/or hot water above 0.5 bar, and temperatures exceeding 110 °C. This delineation ensures clarity regarding which types of boilers are subject to its stringent requirements, thereby enhancing compliance for manufacturers and operators within the specified parameters. One of the core strengths of this standard lies in its thorough treatment of safety aspects associated with pressure-related hazards. By adhering to essential safety requirements outlined in Annex I of the Pressure Equipment Directive, the standard guarantees that users can rely on the safety and functionality of their water-tube boilers. The emphasis on proper design, manufacturing, testing, and inspection techniques establishes a robust baseline for boiler assembly quality and operational safety. The inclusion of protective measures against unavoidable hazards and the provision of information regarding residual risks significantly contribute to the relevance of EN 12952-1:2015 in contemporary boiler operations. This forward-thinking approach not only aids in risk mitigation but also fosters a culture of safety among stakeholders. The standard's acknowledgment of the impossibility of covering all potential operational scenarios further underscores its pragmatic nature, preparing users for a variety of challenges while maintaining rigorous safety standards. Additionally, the detailed definition of the boiler assembly is a significant advantage of this standard. By explicitly listing components that are integral to the water-tube boiler and auxiliary installations, such as superheaters, reheaters, and associated safety accessories, the standard facilitates clearer communication and understanding among manufacturers, installers, and operators. This detailed assembly framework also assists in the evaluation of safety measures and compliance. Exclusions outlined in the standard, including specific types of boilers, further refine its applicability, ensuring that it targets the most critical areas of concern in boiler safety and operation. This specificity allows manufacturers to focus their efforts on compliance with standards that are most relevant to their equipment type. Overall, EN 12952-1:2015 serves as a vital reference point in the industry, promoting best practices in safety and engineering for water-tube boilers and auxiliary installations. Its systematic approach to safety, comprehensive scope, and clear definitions are instrumental in ensuring that operators and manufacturers can effectively and safely meet their operational requirements.
SIST EN 12952-1:2016 표준은 수관 보일러 및 보조 설치에 대한 일반적인 요구사항을 규명하고 있다. 이 표준은 2리터 이상의 부피를 가진 수관 보일러에 적용하며, 최대 허용 압력 PS가 0.5바를 초과하고 110도 이상의 온수를 생성하는 보일러에 해당한다. 이 표준의 주요 목표는 압력 설비 지침의 부록 I에 따른 필수 안전 요구 사항을 충족하여 수관 보일러의 안전을 보장하는 것이다. 이 표준의 강점은 설계, 제조, 시험 및 검사 방법의 적절한 적용을 통해 안전성을 강화하는 데 있다. 또한, 불가피한 위험으로부터의 보호 조치를 제공하고, 잔여 위험에 대한 정보 및 위험을 줄이기 위한 다른 조치를 포함하여 포괄적인 안전 관리 시스템을 구축할 수 있도록 돕는다. 이러한 특징들이 수관 보일러의 압력 관련 위험, 특히 과열로 인한 압력 유지 구성 요소의 실패에 대한 위험을 충분히 반영하고 있다. 보일러 조립 부분에서는 수관 보일러와 모든 압력 부품, 그리고 전기적으로 또는 연료에 의해 가열되는 기기들이 포함된다. 이 표준은 제조업체의 재량에 따라 격리 가능한 초과열 기기, 재가열기 및 관련 배관을 통합할 수 있는 유연성을 제공한다. 또한, 보일러의 작동에 필요한 추가 장비와 구성 요소를 명확히 하여 안전하고 효율적인 보일러 시스템의 개발을 지원한다. 엑스클루전 조항에서는 이 표준이 고정 보일러 외의 다른 유형의 보일러에 적용되지 않음을 명시하며, 이는 특정과 같은 제약을 통해 수관 보일러에 특화된 요구사항에 더 집중할 수 있도록 한다. 이러한 점에서 SIST EN 12952-1:2016 표준은 수관 보일러의 안정성을 극대화하고, 고유한 안전 요구 사항을 충족하는 데 매우 중요한 역할을 수행하고 있다고 할 수 있다.
この標準文書「EN 12952-1:2015」は、水管ボイラーおよびその補助設備に関する包括的なガイドラインを提供しています。具体的には、容量が2リットルを超える水管ボイラーが対象であり、最大許容圧力0.5バールを超え、温度が110°Cを超える蒸気や温水の生成に関連します。この標準の目的は、圧力機器指令の附属書Iに基づく必須安全要件を満たし、水管ボイラーの安全性を確保することです。 標準の強みは、設計、製造、試験および検査手法の適切な適用を重視している点です。加えて、回避不可能な危険に対する保護措置を提供し、残留危険やリスクを軽減するための情報も提供しています。これにより、実際の運用環境における圧力関連の危険（過熱による圧力保持部品の故障など）を考慮した要件が定められています。 また、ボイラーの組み立てに関する定義が明示されており、すべての圧力部品や関連する安全アクセサリーが組み込まれていることが説明されています。このように、ユーザーが安全かつ効率的にボイラーを運用できるように配慮されています。さらに、製造業者の裁量により、追加の機器やコンポーネントが組み込まれる可能性もあるため、柔軟性が確保されています。 標準文書には、ボイラーの支持構造、断熱材、煙道の動力ファンなど、ボイラー操作に必要な他の設備についても言及がありますが、電気ボイラーや原子力プライマリ回路のような特定のボイラータイプは除外されています。このように、EN 12952-1:2015は、特定の条件下での安全性を考慮しながらも、さまざまな状況に対応するための包括的な枠組みを提供しているため、非常に関連性の高い標準となっています。
Die Norm EN 12952-1:2015 behandelt Wasserrohrkessel und zugehörige Anlagen und bietet einen umfassenden Rahmen für die Sicherheit und das Design dieser Systeme. Der Anwendungsbereich der Norm erstreckt sich auf Wasserrohrkessel mit einem Volumen von mehr als zwei Litern, die Dampf und/oder heißes Wasser bei einem maximalen Druck über 0,5 bar und Temperaturen über 110 °C erzeugen. Dies zeigt bereits die Relevanz der Norm im Bereich der Druckanlagen, da sie sicherstellt, dass alle wesentlichen Sicherheitsanforderungen gemäß Anhang I der Druckgeräterichtlinie erfüllt sind. Eine der Stärken dieser Norm ist die gründliche Betrachtung von druckbezogenen Gefahren, die speziell für Wasserrohrkessel gelten. Sie umfasst nicht nur die Design-, Fertigungs- und Prüfmethoden, sondern auch die notwendigen Schutzmaßnahmen gegen nicht vermeidbare Gefahren. Weiterhin bietet sie Informationen über verbleibende Gefahren und Risikominderungsmaßnahmen, die in den verschiedenen Teilen der Norm eingebunden sind. Dies ist besonders wichtig, da es in der Praxis oft nicht möglich ist, alle potenziellen Gefahrensituationen zu erfassen. Die Norm definiert auch den Aufbau des Kessels, einschließlich aller druckhaltenden Komponenten und verbindenenden Rohrleitungen. Darüber hinaus berücksichtigt sie die Integration von weiteren Komponenten nach Ermessen des Herstellers, was eine hohe Flexibilität und Anpassungsfähigkeit in der Anwendung ermöglicht. Auch andere Anlagenteile, die für den Betrieb des Kesselwerks notwendig sind, werden in der Norm behandelt, sodass sie eine umfassende Grundlage für den gesamten Kesselbetrieb bietet. Ein weiterer bemerkenswerter Aspekt der Norm ist, dass bestimmte Anlagentypen, wie stationäre Kessel, nicht abgedeckt sind. Dies schafft Klarheit und Präzision im Geltungsbereich und sorgt dafür, dass die Anwender der Norm genau wissen, für welche Anwendungen sie anwendbar ist. Insgesamt ist die EN 12952-1:2015 eine wesentliche Norm, die durch ihren klaren Fokus auf Sicherheit, Design und Betrieb ein hohes Maß an Schutz für Wasserrohrkessel und deren Anlagen gewährleistet.
