The EN 1595:1997 standard presents a comprehensive framework for the design, manufacture, and testing of pressure equipment made from borosilicate glass 3.3. Its scope is particularly important as it specifies essential material requirements, drawing attention to the unique properties of borosilicate glass, including its coefficient of mean linear thermal expansion of (3.3 +/- 0.1) x 10-6 K-1. This specificity ensures that manufacturers maintain a consistent quality and performance standard while working with this material. One of the strengths of EN 1595:1997 lies in its detailed inspection and testing requirements, which bolster safety and reliability for pressure equipment applications, including vessels, pipes, and valves. The standard sets forth rigorous criteria that enhance manufacturing processes and ensure that all components meet necessary safety regulations and operational demands. Further, the exclusion of certain items such as circular, flat, and tubular sight glasses, along with equipment made from borosilicate glass with a different coefficient of thermal expansion, streamlines the focus of the standard. This clear delineation of intent helps manufacturers and designers direct their efforts towards compliance in the specified area, enhancing the relevance of the standard in practice. Overall, EN 1595:1997 serves as a crucial reference point for the industry's approach to safety and quality in pressure equipment made from borosilicate glass 3.3, ensuring that all aspects from design to testing are guided by a well-established set of rules.

Die Norm EN 1595:1997 legt grundlegende Anforderungen für die Gestaltung, Herstellung und Prüfung von Druckgeräten fest, die aus Borosilikatglas 3.3 bestehen. Der Anwendungsbereich dieser europäischen Norm umfasst damit sowohl Behälter als auch Rohre und Armaturen, die für den Einsatz unter Druck ausgelegt sind. Ein zentrales Merkmal dieser Norm ist die Spezifikation des mittleren linearen thermischen Ausdehnungskoeffizienten von (3,3 +/- 0,1) x 10-6 K-1, was eine präzise Grundlage für die thermische Stabilität der Materialien bietet. Die Stärke der Norm liegt in ihrer detaillierten Aufschlüsselung der Anforderungen an die Materialauswahl, das Design und die Inspektionsprozesse. Solche strengen Kriterien sichern nicht nur die Sicherheit und Zuverlässigkeit der Druckgeräte, sondern fördern auch die Konsistenz in der Herstellung und den Einsatz von Borosilikatglas 3.3. Die Norm zielt darauf ab, potenzielle Risiken bei der Nutzung von Druckgeräten zu minimieren und gleichzeitig die Anforderungen an die Qualität und Leistung der Produkte zu erfüllen. Die Relevanz dieser Norm wird durch die Tatsache unterstützt, dass sie spezifische Ausschlüsse für bestimmte Arten von Sichtgläsern und für Borosilikatglas mit abweichenden thermischen Ausdehnungskoeffizienten definiert.

Son domaine d'application est essentiel dans des industries où l'utilisation d'équipements en verre est indispensable, comme dans les laboratoires et les installations chimiques. Elle couvre spécifiquement les exigences relatives aux matériaux, à la conception, à l'inspection, aux essais et au marquage de ces équipements, garantissant ainsi des niveaux élevés de sécurité et de performance. L'un des points forts de cette norme est sa précision dans la définition des exigences techniques, notamment en ce qui concerne le coefficient de dilatation thermique linéaire moyen du verre borosilicate. Avec un coefficient de (3,3 ± 0,1) x 10^-6 K^-1, elle assure une adéquation entre les différents composants sous pression, ce qui est crucial pour éviter les défaillances dues aux variations de température. De plus, la norme exclut clairement certains types d'équipements, tels que les verres de vue circulaires, plats et tubulaires, ainsi que ceux fabriqués à partir de verre borosilicate ayant un autre coefficient de dilatation thermique. Cette stratégie de délimitation élargit la pertinence de la norme pour les utilisateurs en évitant les ambiguïtés et en garantissant que seules les applications appropriées soient couvertes. Dans un environnement où le contrôle de la qualité et la conformité réglementaire sont des préoccupations majeures, la norme EN 1595 se révèle pertinente et utile.
