Die Norm EN 73:2020 beschäftigt sich mit der Haltbarkeit von Holz und holzbasierten Produkten und legt ein Verfahren zur beschleunigten Alterung von behandeltem Holz vor, das vor biologischen Tests durchgeführt wird. Der Anwendungsbereich der Norm ist klar definiert: Sie beschreibt ein evaporatives Alterungsverfahren, das für Prüfmuster von Holz sowie holzbasierten Produkten gilt. Dies schließt sowohl behandeltes als auch unbehandeltes Holz, modifiziertes Holz und Holzwerkstoffe ein, unabhängig davon, ob sie einer schützenden Behandlung unterzogen wurden oder nicht. Ein wesentlicher Vorteil der EN 73:2020 liegt in ihrer breiten Anwendbarkeit und Flexibilität. Das beschriebene Verfahren ermöglicht es, die Alterung von Holzprodukten realistisch nachzuvollziehen, bevor sie ökologischen oder biologischen Tests ausgesetzt werden. So bietet die Norm eine wertvolle Grundlage zur Bewertung der Leistungsfähigkeit und Langlebigkeit von Holzmaterialien unter verschiedenen Bedingungen. Ein weiterer Stärke der Norm ist die Methodik selbst, die auf wissenschaftlichen Erkenntnissen beruht und somit eine fundierte Bewertung der biologischen Resistenz von Holzprodukten ermöglicht. Das evaporative Alterungsverfahren gewährleistet konsistente Ergebnisse, die für Forschung und Entwicklung, sowie für die Qualitätssicherung in der Holzindustrie von großer Bedeutung sind. Die Relevanz der EN 73:2020 ergibt sich aus der steigenden Nachfrage nach nachhaltigen und langlebigen Holzprodukten. Da der Markt immer mehr auf Haltbarkeit und ökologische Verträglichkeit Wert legt, ist die Norm ein unverzichtbares Instrument für Hersteller, die die langfristige Leistung ihrer Produkte gewährleisten möchten. Durch die Standardisierung des Alterungsprozesses trägt die EN 73:2020 dazu bei, Transparenz und Vertrauen in die Eigenschaften von Holz und holzbasierten Produkten zu schaffen.
The standard EN 73:2020 offers a comprehensive framework for the durability examination of wood and wood-based products through an accelerated ageing process. Its primary focus is the evaporative ageing procedure, which is crucial for preparing test specimens that will undergo various biological tests. One of the significant strengths of this standard lies in its broad applicability. It is not limited to just treated wood; instead, it encompasses untreated wood, modified wood, and wood-based panel products, regardless of whether they have been subjected to preservative treatments. This inclusivity ensures that a wide range of materials can be assessed for their durability, making the standard particularly relevant in today's diverse wood product market. Furthermore, the document provides clear guidelines and methodologies that enhance consistency and reproducibility in testing. By defining an evaporative ageing procedure, EN 73:2020 allows researchers and manufacturers to reliably simulate the effects of prolonged exposure to environmental conditions, which is vital for understanding long-term performance. The emphasis on biological testing following the ageing process is essential, given the increasing concerns about the longevity and environmental impact of wood products. This standard supports sustainable practices by facilitating assessments that contribute to the development of more resilient materials, thus bolstering the credibility of wood products in competitive markets. Overall, EN 73:2020 stands out as a critical standard in the wood industry, providing a robust procedure for evaluating durability through accelerated ageing. Its strengths in applicability, consistency, and relevance significantly contribute to advancing quality assurance in wood and wood-based products.
