Copper and copper alloys - Seamless, round tubes for heat exchangers
This European Standard specifies the composition, property requirements and tolerances on dimensions and form for seamless round drawn copper and copper alloy tubes for heat exchangers, condensers, evaporators and desalination equipment. It gives guidelines for copper and copper alloy tubes supplied in the size range from 6 mm up to and including 76 mm outside diameter and from 0,5 mm up to and including 3 mm wall thickness.
The sampling procedures and the methods of test for verification of conformity to the requirements of this European Standard are also specified.
Kupfer und Kupferlegierungen - Nahtlose Rundrohre für Wärmeaustauscher
Diese Europäische Norm legt die Zusammensetzung, die Anforderungen an die Eigenschaften, Grenzabmaße und Formtoleranzen für nahtlosgezogene Rundrohre aus Kupfer und Kupferlegierungen für Wärmeaus-tauscher, Kondensatoren, Verdampfer und Entsalzungsanlagen fest. Diese Norm gilt für Rohre aus Kupfer und Kupferlegierungen im Maßbereich von 6 mm bis 76 mm Außendurchmesser und von 0,5 mm bis 3 mm Wanddicke. Der Ablauf der Probenentnahme und die Prüfverfahren zur Feststellung der Übereinstimmung mit den Anforderungen dieser Europäischen Norm sind ebenfalls festgelegt.
Cuivre et alliages de cuivre - Tubes ronds sans soudure pour échangeurs thermiques
La présente Norme européenne spécifie la composition, les caractéristiques et les tolérances de dimensions
et de formes des tubes ronds sans soudure en cuivre et alliages de cuivre destinés aux échangeurs
thermiques, aux condenseurs, aux évaporateurs et aux installations de désalinisation. Elle est applicable aux
tubes en cuivre et en alliages de cuivre fournis dans une plage de diamètre extérieur de 6 mm à 76 mm
compris, et d'épaisseur de paroi de 0,5 mm à 3 mm compris.
Les modes opératoires d'échantillonnage et les méthodes d'essai pour la vérification de la conformité aux
exigences de la présente Norme européenne sont également spécifiés.
