La norme SIST EN 12050-2:2015 constitue un texte régulateur essentiel pour les installations de relevage des eaux usées non fécales dans les bâtiments et les sites. Son champ d'application est clairement défini, visant spécifiquement les dispositifs de relevage qui permettent le drainage d'emplacements situés en dessous du niveau d'inondation, tout en empêchant tout retour d'eaux usées dans les bâtiments. L'un des points forts de cette norme réside dans sa flexibilité, stipulant que ces installations peuvent être préfabriquées ou livrées sous forme de kits à assembler sur site. Cela permet aux professionnels du secteur d'avoir un choix varié en fonction des besoins spécifiques des projets. De plus, la norme précise des exigences générales et des principes de construction et d'essai, ce qui garantit une cohérence dans les performances des systèmes de relevage. Un autre avantage significatif est la prise en compte des systèmes qui ne sont pas préfabriqués, mais plutôt composés de composants individuels achetés chez différents fournisseurs. Cela favorise l’innovation et la personnalisation des installations, tout en répondant aux besoins diversifiés du marché. Les exigences de construction et de test pour les vannes de non-retour utilisées dans les installations de relevage sont également abordées dans la norme EN 12050-4, renforçant encore la couverture que cette norme propose dans le domaine des eaux usées. En somme, la norme SIST EN 12050-2:2015 est hautement pertinente pour les professionnels des installations de relevage des eaux usées non fécales, garantissant non seulement la sécurité et la fiabilité des systèmes, mais aussi leur conformité aux exigences de performance exigées par les différents acteurs du secteur.
Die EN 12050-2:2015 ist eine bedeutende europäische Norm, die sich mit Hebeanlagen für fäkalienfreies Abwasser befasst. Ihr Anwendungsbereich erstreckt sich auf die Entwässerung von Standorten unterhalb der Überflutungsebene innerhalb von Gebäuden und auf Grundstücken. Die Norm zielt darauf ab, Rückflüsse von Abwasser in Gebäude zu verhindern, was ein entscheidender Aspekt für die Sicherstellung der hygienischen Bedingungen in Wohn- und Geschäftsräumen ist. Ein großer Vorteil dieser Norm ist die Flexibilität, die sie bei der Anwendung bietet. Die Hebeanlagen können sowohl vorgefertigt als auch als Bausatz geliefert werden, der vor Ort montiert wird.

SIST EN 12050-2:2015 문서는 건물 및 부지에서 배수 레벨 이하의 위치에서 발생하는 비대변 폐수를 위한 리프팅 플랜트에 대한 유럽 표준으로, 폐수가 건물로 역류하는 것을 방지하기 위해 설계되었습니다. 이 표준은 사전 제작된 리프팅 플랜트와 현장에서 조립할 수 있는 조립식 키트를 포함하여, 폐수 처리를 위한 다양한 리프팅 시스템의 범위를 포괄합니다. 우선 이 표준의 강점은 비대변 폐수를 처리하는 리프팅 플랜트의 일반 요구 사항과 기본 건축 및 테스트 원칙을 명확하게 규정하고 있다는 점입니다. 표준은 사용되는 재료에 대한 정보와 성능의 일관성을 평가 및 검증하는 방법도 포함하고 있어, 실제 적용에 있어 신뢰성을 높입니다. 특히, 이 표준은 비대변 폐수의 리프팅 플랜트를 구성할 때, 서로 다른 공급자로부터 개별 구성 요소를 구입하여 현장에서 조립하는 경우에도 적용됩니다. 또한 SIST EN 12050-2:2015는 비대변 폐수가 아닌 기타 치수의 리프팅 플랜트에 대한 요구 조건을 구체적으로 규정하고 있으며, 이는 건물 내부의 특정 배수 시스템에 맞춘 설계를 가능하게 합니다. EN 12050 4에 규정된 비회수 밸브의 건설 및 테스트 요구 사항도 함께 제시되어 있어, 폐수 리프팅 플랜트의 전체적인 안전성과 효율성을 보장합니다. 이 표준은 건물 및 부지의 다양한 환경에서 필요한 비대변 폐수 처리 솔루션을 제공하는 데 핵심적인 역할을 하고 있으며, 따라서 설계자와 시공업체 모두에게 매우 중요한 문서입니다.
SIST EN 12050-2:2015は、建物や敷地における非汚水の排水を目的とした昇圧装置に関するヨーロッパ標準であり、その適用範囲は非常に明確です。この標準は、洪水レベル以下に位置する場所からの非汚水排出を目的とし、未処理の汚水の建物への逆流を防ぐ機能を提供します。これにより、建物の衛生状態を維持するための重要な役割を果たします。 この標準の強みは、プレハブ型の昇圧装置だけでなく、異なる供給者から調達した個々の部品を用いて現場で組み立てられた装置にも適用される点です。これにより、様々なニーズに対応できる柔軟性が生まれると同時に、地域における建設環境への適応性が高まります。 さらに、SIST EN 12050-2:2015は、衛生的かつ効果的な排水システムの設計や設置に関する一般的な要件、基本的な建設および試験原則を明確に示しており、材料の選定や性能の一貫性の評価といった重要な指針を提供します。特に、非戻り弁に関する建設および試験要件は、標準EN 12050-4によって定められており、排水昇圧装置の信頼性をさらに強化しています。 この標準は、特に住宅や商業施設が洪水の危険にさらされる地域での適切な排水管理に不可欠であり、その関連性は高いと言えます。排水システムの安全性と機能性を保つための厳格な基準を満たすことが求められるため、建築業界や環境保護に対しても重要な影響を与えるものです。 全体として、SIST EN 12050-2:2015は、非汚水の昇圧装置に関する明確で包括的なガイドラインを提供し、建物及び敷地内の排水管理を一層向上させるものであり、業界の発展に寄与する標準と言えるでしょう。
The EN 12050-2:2015 standard provides a comprehensive framework for the design, construction, and testing of wastewater lifting plants specifically for faecal-free wastewater within buildings and sites. Its primary scope addresses the essential requirement of preventing backflow in locations situated below flood levels, which is critical for maintaining the integrity and safety of building infrastructure. One of the key strengths of this standard is its detailed specification of requirements, covering both prefabricated lifting plants and those that are assembled on-site from kits or individual components. This flexibility allows for a wide range of applications, accommodating diverse installation needs across different building types and conditions. By including provisions for both prefabricated solutions and custom assemblies, the standard supports a more tailored approach to wastewater management, ensuring that specific site challenges can be effectively addressed. The document outlines essential construction and testing principles, which serve to enhance the reliability and performance of lifting plants for faecal-free wastewater. In addition, it incorporates information regarding materials and the assessment and verification of constancy of performance, ensuring that the components used meet stringent quality and safety standards. This focus on performance consistency is vital for maintaining operational efficiency and minimizing maintenance issues in the long term. Moreover, the inclusion of requirements for non-return valves, referenced in EN 12050-4, further enhances the standard by establishing critical performance metrics for a key component in wastewater lifting systems. This aspect bolsters the overall functionality of the systems and aids in preventing potential backflow events, a significant concern in wastewater management. Although EN 12050-2:2015 explicitly excludes pumping installations for drain and sewer systems outside of buildings, it effectively fills a vital niche by focusing solely on faecal-free wastewater applications. This clarity ensures that users can readily identify the appropriate standard for their specific operational needs without confusion. In summary, the EN 12050-2:2015 standard stands out for its relevant application to lifting plants for faecal-free wastewater, offering a robust framework that addresses key concerns in wastewater management, while promoting best practices in construction and testing. Its comprehensive scope and detailed requirements make it a valuable resource for professionals involved in the design and implementation of wastewater lifting systems.
