(Main)Copper and copper alloys - Seamless, round tubes for general purposes
Copper and copper alloys - Seamless, round tubes for general purposes
This European Standard specifies the composition, property requirements and tolerances on dimensions and form for seamless round drawn copper and copper alloy tubes for general purposes supplied in the size range from 3 mm up to and including 450 mm outside diameter and from 0,3 mm up to and including 20 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.
NOTE Tubes having an outside diameter less than 80 mm and/or a wall thickness greater than 2 mm in certain alloys are most frequently used for free machining purposes which are specified in EN 12168.
Kupfer und Kupferlegierungen - Nahtlose Rundrohre zur allgemeinen Verwendung
Diese Europäische Norm legt die Zusammensetzung, die Anforderungen an die Eigenschaften, Grenzabmaße und Formtoleranzen für nahtlose, gezogene Rundrohre zur allgemeinen Verwendung aus Kupfer und Kupferlegierungen fest. Sie gilt für den Maßbereich von 3 mm bis 450 mm Außendurchmesser und eine Wanddicke von 0,3 mm bis 20 mm.
Die Probenentnahme und die Prüfverfahren zur Feststellung der Übereinstimmung mit den Anforderungen dieser Europäischen Norm sind ebenfalls festgelegt.
ANMERKUNG Rohre aus bestimmten Legierungen mit einem Außendurchmesser kleiner als 80 mm und/oder einer Wanddicke größer als 2 mm werden sehr häufig für die spanende Bearbeitung eingesetzt. Diese Rohre sind in EN 12168 genormt.
Cuivre et alliages de cuivre - Tubes ronds sans soudure pour usages généraux
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 pour usages généraux fournis dans une plage de diamètre extérieur de 3 mm à 450 mm compris, et d’épaisseur de paroi de 0,3 mm à 20 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.
NOTE Les tubes ayant un diamètre extérieur de moins de 80 mm et/ou une épaisseur de paroi supérieure à 2 mm dans certains alliages sont le plus souvent utilisés pour le décolletage tel que spécifié dans l'EN 12168.
Baker in bakrove zlitine - Nevarjene cevi z okroglim prerezom za splošno uporabo
Ta evropski standard določa sestavo, zahteve glede značilnosti ter odstopanja glede mer in oblike za nevarjene cevi z okroglim prerezom iz vlečenega bakra in bakrovih zlitin za splošno uporabo, ki se dobavljajo z zunanjim premerom velikosti od 3 mm do vključno 450 mm in debelino stene od 0,3 mm do vključno 20 mm.
Določeni so tudi postopki vzorčenja in preskusne metode za preverjanje skladnosti z zahtevami tega evropskega standarda.
OPOMBA: Cevi iz določenih zlitin z zunanjim premerom, manjšim od 80 mm, in/ali debelino stene, večjo od 2 mm, se najpogosteje uporabljajo za namene brez strojne uporabe, ki so določeni v standardu EN 12168.
