Copper and copper alloys - Rolled, finned, seamless tubes for heat exchangers
This European Standard specifies the composition, property requirements and tolerances on dimensions and form for rolled, finned, seamless copper and copper alloy tubes for heat exchangers. It gives guidelines for copper and copper alloy tubes supplied in the size range from 6 mm up to and including 35 mm outside diameter; from 1 mm up to and including 3 mm wall thickness of the unfinned section; and with fin height up to and including 1,5 mm.
The sampling procedures and the methods of testing for verification of conformity to the requirements of this European Standard are also specified.
Kupfer und Kupferlegierungen - Nahtlose, gewalzte Rippenrohre für Wärmeaustauscher
Diese Europäische Norm legt die Zusammensetzung, die Anforderungen an die Eigenschaften, die Grenzabmaße und die Formtoleranzen für nahtlose, gewalzte Rippenrohre aus Kupfer und Kupferlegierungen für Wärmeaustauscher fest. Diese Norm gilt für Rohre aus Kupfer und Kupferlegierungen im Maßbereich von 6 mm bis 35 mm Außendurchmesser und von 1 mm bis 3 mm Wanddicke im unberippten Querschnitt, mit einer Rippenhöhe bis 1,5 mm. Der Ablauf der Probenentnahme und die Prüfverfahren zur Feststellung der Übereinstimmung mit den Anfor-derungen dieser Europäischen Norm sind ebenfalls festgelegt.
Cuivre et alliages de cuivre - Tubes sans soudure à ailettes pour échangeurs thermiques
La présente Norme européenne spécifie la composition, les caractéristiques et les tolérances admises sur les dimensions et les formes des tubes sans soudure à ailettes, en cuivre et en alliages de cuivre, destinés aux échangeurs thermiques. Elle est applicable aux tubes en cuivre et en alliages de cuivre fournis dans une plage de diamètre extérieur de 6 mm à 35 mm compris, d'épaisseur de paroi de 1 mm à 3 mm compris pour la section sans ailettes et de hauteur d'ailettes inférieure ou égale à 1,5 mm.
Les procédures d'échantillonnage et les méthodes d'essai pour la vérification de la conformité aux exigences de la présente Norme européenne sont également spécifiées.
Baker in bakrove zlitine - Valjane, narebričene, nevarjene cevi za toplotne izmenjevalnike
Ta evropski standard določa sestavo, zahteve glede lastnosti ter odstopanja glede dimenzij in oblike za valjane, narebričene, nevarjene cevi iz vlečenega bakra in bakrovih zlitin za toplotne izmenjevalnike, ki se dobavljajo z zunanjim premerom velikosti od 6 mm do vključno 35 mm in debelino stene od 1 mm do vključno 3 mm pri nenarebričenem preseku, pri čemer je rebro visoko največ 1,5 mm. Določeni so tudi postopki vzorčenja in preskusne metode za preverjanje skladnosti tega standarda.
