Solar energy - Solar thermal collectors - Test methods (ISO 9806:2017)
ISO 9806:2017 specifies test methods for assessing the durability, reliability, safety and thermal performance of fluid heating solar collectors. The test methods are applicable for laboratory testing and for in situ testing.
ISO 9806:2017 is applicable to all types of fluid heating solar collectors, air heating solar collectors, hybrid solar collectors co-generating heat and electric power, as well as to solar collectors using external power sources for normal operation and/or safety purposes. It does not cover electrical safety aspects or other specific properties directly related to electric power generation.
ISO 9806:2017 is not applicable to those devices in which a thermal storage unit is an integral part to such an extent that the collection process cannot be separated from the storage process for making the collector thermal performance measurements.

The SIST EN ISO 9806:2018 standard provides a comprehensive framework for the evaluation of solar thermal collectors, specifically focusing on their durability, reliability, safety, and thermal performance. This standard is critical for manufacturers and stakeholders in the solar energy sector, particularly as it pertains to fluid heating solar collectors. One of the primary strengths of the ISO 9806:2017 standard is its broad applicability, as it encompasses various types of solar collectors, including air heating solar collectors and hybrid systems that generate both heat and electric power. This inclusivity ensures that diverse technologies can be assessed under uniform test methods, facilitating more consistent performance comparisons across different systems. The test methods specified within the standard are meticulously designed for both laboratory and in situ testing, allowing for flexibility in how evaluations can be conducted. This is particularly relevant as real-world conditions can significantly influence a collector's performance, and the ability to test in situ provides valuable insights into operational efficacy. Moreover, the standard provides a clear outline of the parameters to be assessed, enhancing the reliability of performance assessments. For instance, while it does not address electrical safety aspects directly linked to electric power generation, it focuses on pertinent factors affecting thermal performance, which are crucial for determining the operational viability of solar thermal systems. It is also noteworthy that the standard explicitly states its limitations regarding integral thermal storage units, which is important for clear understanding among manufacturers and users about what aspects of solar technology are covered. This specificity helps in minimizing misunderstanding in the application of the standard and reinforces the quality of data derived from performance assessments. Overall, the relevance of SIST EN ISO 9806:2018 in the evolving landscape of solar energy solutions cannot be overstated. As solar technology advances and becomes more integral to sustainable energy solutions, standards like ISO 9806:2017 will play a vital role in ensuring that products are rigorously tested and validated for efficiency and safety. This will, in turn, bolster consumer confidence and promote wider adoption of solar energies.
SIST EN ISO 9806:2018 문서는 태양 에너지 분야의 중요한 기준으로, 태양열 집열기의 내구성, 신뢰성, 안전성 및 열 성능을 평가하기 위한 시험 방법을 명시하고 있습니다. 이 표준은 실험실 탐색 및 현장 테스트에 적용 가능한 다양한 시험 방법을 제시하여, 사용자들이 태양열 집열기의 성능을 종합적으로 이해하고 확인할 수 있도록 돕습니다. ISO 9806:2017의 주요 장점 중 하나는 모든 종류의 유체 가열 태양열 집열기에 적용 가능하다는 점입니다. 이는 공기 가열 집열기나 열과 전기를 동시에 생산하는 하이브리드 태양열 집열기 등 다양한 시스템에서도 유효하므로, 태양열 에너지 기술의 폭넓은 활용성을 증대시킵니다. 또한 외부 전원 소스를 사용하여 일반 작동 및 안전 목적을 지원하는 태양열 집열기에도 적용될 수 있는 점에서 이 표준의 적용 범위가 매우 넓다는 것을 알 수 있습니다. 하지만 ISO 9806:2017는 전기 안전 측면이나 전력 생성과 직결된 특정 특성에 대해서는 다루지 않으므로, 이러한 측면에 대한 추가적인 기준이 필요할 수 있습니다. 또한, 열 저장 장치가 집열기의 불가분의 일부로서 설치된 경우에는 이 기준의 적용에서 제외되므로, 해당 조건을 충족하지 않는 장치들에 대한 시험 및 평가를 위한 별도의 기준이 필요할 것으로 보입니다. 결론적으로, SIST EN ISO 9806:2018 표준은 태양열 집열기의 성능을 체계적으로 평가할 수 있는 신뢰할 수 있는 방법론을 제공함으로써, 태양열 에너지 시스템의 발전과 적용에 있어 매우 중요하고 관련성이 높은 기준이라고 할 수 있습니다.
SIST EN ISO 9806:2018は、太陽熱コレクターに関する試験方法を詳述した重要な標準です。この標準は、流体加熱型太陽コレクターの耐久性、信頼性、安全性、及び熱性能を評価するための試験方法を規定しています。その適用範囲は、実験室での試験だけでなく、現場での試験にも及びます。 この標準の強みは、あらゆる種類の流体加熱型太陽コレクターや空気加熱型太陽コレクター、熱と電力を共同で生成するハイブリッド型コレクター、さらには通常の運転や安全目的のために外部電源を使用する太陽コレクターに適用される点です。これにより、さまざまなシステムや技術に対して一貫した品質評価を提供します。 ISO 9806:2017は特に、コレクターの熱性能測定に関して、熱蓄積ユニットがそのプロセスの一部として密接に結びついている機器には適用されないことを明確にしています。この点は、試験結果が正確であるための重要な考慮事項です。 全体として、SIST EN ISO 9806:2018は、太陽熱エネルギーの利用を促進するために必要な試験方法を体系的にまとめており、その関連性は今後の再生可能エネルギー分野の発展に寄与するでしょう。
Die Norm SIST EN ISO 9806:2018 befasst sich umfassend mit den Prüfmethoden zur Bewertung der Haltbarkeit, Zuverlässigkeit, Sicherheit und thermischen Leistung von Flüssigkeitsheizungs-Solarkollektoren. Sie ist ein wichtiger Standard, der die Entwicklung und den Einsatz von Solarthermiekollektoren in der heutigen Energielandschaft unterstützt. Ein herausragendes Merkmal dieser Norm ist ihre Vielseitigkeit. Sie deckt sämtliche Typen von Flüssigkeitsheizungs-Solarkollektoren ab, einschließlich der Luftheizungs-Solarkollektoren, hybriden Solarkollektoren, die sowohl Wärme als auch elektrische Energie erzeugen, sowie Kollektoren, die externe Energiequellen für den normalen Betrieb und/oder Sicherheitszwecke benötigen. Diese umfassende Anwendbarkeit macht die Norm für Hersteller und Prüfinstitutionen von großer Bedeutung, da sie eine einheitliche Grundlage für Tests und Bewertungen bietet. Die Norm ist auch erwähnenswert, weil sie die Möglichkeit bietet, sowohl Labortests als auch In-situ-Tests durchzuführen. Dies ermöglicht eine realistische Einschätzung der Funktionalität und Leistung der Solarkollektoren unter tatsächlichen Betriebsbedingungen. Die Berücksichtigung von Tests in beiden Szenarien stärkt die Glaubwürdigkeit der ermittelten Ergebnisse und trägt zur Sicherstellung der Qualität bei. Besonders relevant ist die klare Abgrenzung von den Aspekten der elektrischen Sicherheit, da die Norm gezielt auf thermische Leistung fokussiert. Dies ermöglicht es den Nutzern, sich auf die spezifischen Eigenschaften von Solarthermiekollektoren zu konzentrieren, ohne dass eine Vermischung mit anderen Technologien erfolgt, die elektrische Energie betreffen. Außerdem ist die Festlegung, dass Norm nicht für Geräte gilt, bei denen eine thermische Speichereinheit integraler Bestandteil ist, von Bedeutung. Dies stellt sicher, dass die Prüfmethoden für die spezifischen Anforderungen an die thermische Leistung genau und relevant sind. Insgesamt stellt die SIST EN ISO 9806:2018 einen wesentlichen Beitrag zur Standardisierung von Tests im Bereich der Solarthermie dar. Die klaren Richtlinien und umfassenden Prüfmethoden fördern die Sicherheit und Effizienz von Solarkollektoren und unterstützen die Marktakteure bei der Entwicklung und Verbesserung ihrer Produkte im Bereich erneuerbarer Energien.
La norme SIST EN ISO 9806:2018 fournit un cadre exhaustif pour l'évaluation des collecteurs solaires thermiques, grâce à des méthodes d'essai standardisées qui garantissent leur durabilité, fiabilité, sécurité et performance thermique. L'importance de cette norme réside dans sa capacité à s'appliquer à une grande variété de collecteurs solaires, incluant les collecteurs de chaleur fluides, les collecteurs de chaleur d'air, et même les collecteurs hybrides qui génèrent à la fois de la chaleur et de l'électricité. Les méthodes d'essai spécifiées dans cette norme sont conçues pour être utilisées aussi bien en laboratoire qu'en situation réelle, ce qui renforce leur pertinence pour les fabricants et les installateurs de systèmes de chauffage solaire. Cette flexibilité permet donc d'assurer que les collecteurs sont non seulement efficaces, mais aussi adaptés aux conditions réelles d'utilisation. Un autre point fort de la norme ISO 9806:2017 est son approche systématique qui exclut délibérément les aspects de sécurité électrique et d'autres propriétés directement liées à la génération d'énergie électrique. Cela permet aux utilisateurs de se concentrer pleinement sur les performances thermiques des collecteurs solaires, ce qui est essentiel dans le cadre de l'optimisation des systèmes de chauffage solaire. Cependant, la norme ne couvre pas les dispositifs où une unité de stockage thermique joue un rôle intégral dans le processus de collecte, ce qui pourrait limiter son application dans certains systèmes intégrés. Néanmoins, cette spécification assure que les mesures de performance thermique des collecteurs sont précises et fiables, renforçant ainsi la confiance des utilisateurs et des parties prenantes dans l'efficacité des technologies solaires. Enfin, la norme SIST EN ISO 9806:2018 représente une ressource essentielle pour quiconque s'engage dans le développement et l'implémentation des solutions d'énergie solaire, contribuant ainsi à l'avancement des énergies renouvelables et à la transition énergétique globale.
