Copper and copper alloys - Seamless, round copper capillary tubes
This European Standard specifies the composition, property requirements and tolerances on dimensions and on form for seamless round copper capillary tubes for use as metering lines for liquids or gases where close controls over the smooth¬ness and dimensions of the bore are required to ensure uniform flow characteristics.
This European Standard applies to capillary tubes in straight lengths, or in coils, in the size range up to and including 6,10 mm outside diameter and from 0,30 mm up to and including 4,45 mm inside diameter which are intended for restrictor applications. 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, runde Kapillarrohre aus Kupfer
Diese Europäische Norm legt die Zusammensetzung, die Anforderungen an die Eigenschaften, Grenzabmaße und Formtoleranzen für nahtlose, runde Kapillarrohre aus Kupfer fest, die als Messleitung für Flüssigkeiten oder Gase verwendet werden, wobei eine enge Kontrolle der Oberflächenbeschaffenheit und der Maße der Bohrung gefordert wird, um eine gleichmäßige Durchflusscharakteristik zu gewährleisten. Diese Europäische Norm gilt für Kapillarrohre in geraden Längen oder in Ringen mit Außendurchmesser des Rohres bis 6,10 mm und Innendurchmesser von 0,30 mm bis 4,45 mm, die für Durchflussbegrenzer vorgesehen sind. Der Ablauf der Probenentnahme und die Prüfverfahren zur Feststellung der Übereinstimmung mit den Anfor-derungen dieser Europäischen Norm sind ebenfalls festgelegt.

La présente Norme européenne spécifie la composition, les exigences relatives aux caractéristiques et les tolérances relatives aux dimensions et à la forme des tuyaux circulaires en cuivre, de faible diamètre, sans soudure, utilisés dans les installations pour compteur d’eau ou compteur à gaz pour lesquels des contrôles minutieux concernant l’absence de rugosité et les dimensions du diamètre intérieur sont nécessaires pour assurer un débit régulier.
La présente Norme européenne s’applique aux tuyaux de faible diamètre, rectilignes ou en couronne, d’un diamètre extérieur inférieur ou égal à 6,10 mm et d’un diamètre intérieur compris entre 0,30 mm et 4,45 mm, qui sont destinés à des applications de réduction de débit.
Les modes opératoires d’échantillonnage et les méthodes d’essai de vérification de la conformité aux exigences de la présente Norme européenne sont également spécifiés.
Baker in bakrove zlitine - Nevarjene kapilarne cevi z okroglim prerezom
Ta evropski standard določa sestavo, zahteve v zvezi z lastnostmi ter tolerance pri dimenzijah in obliki za nevarjene kapilarne cevi z okroglim prerezom za uporabo v merilnih vodih za tekočine ali pline, kjer je potrebno strogo preverjanje gladkosti in dimenzij izvrtine za zagotavljanje enakih lastnosti pretoka. Ta standard se uporablja za ravne kapilarne cevi ali kapilarne cevi v tuljavah velikosti do vključno 6,10 mm zunanjega premera in od 0,30 mm do vključno 4,45 mm notranjega premera za uporabo v obliki omejeval. Določeni so tudi postopki vzorčenja in preskusne metode za preverjanje skladnosti z zahtevami iz tega evropskega standarda.
