Copper and copper alloys - Seamless, round tubes for air conditioning and refrigeration - Part 2: Tubes for equipment

This European Standard specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes, smooth or inner finned, used for heat exchangers and their internal connecting pipes in the manufacturing of refrigeration and air conditioning equipment.
It is applicable to tubes with an outside diameter from 3,97 mm up to and including 219 mm.
NOTE   The tubes are supplied in straight length in the material conditions hard, half-hard or skin hard or as coils in the material conditions light annealed or soft annealed.

Kupfer und Kupferlegierungen - Nahtlose Rundrohre für die Kälte- und Klimatechnik - Teil 2: Rohre für Apparate

Diese Europäische Norm legt die Anforderungen, Probenentnahme, Prüfverfahren und die Lieferbedingungen für nahtlose Rundrohre aus Kupfer mit glatter oder berippter Innenoberfläche fest, die für Wärmeaustauscher und ihre inneren Verbindungsrohre bei der Herstellung von Apparaten der Kälte- und Klimatechnik verwendet werden.
Sie gilt für Rohre mit einem Außendurchmesser von 3,97 mm bis 219 mm.
ANMERKUNG   Die Rohre werden in geraden Längen, im Zustand hart oder halbhart oder durch Richten gehärtet, oder als Spulen, im Zustand leicht geglüht oder weich geglüht, geliefert.

Cuivre et alliages de cuivre - Tubes ronds sans soudure pour l'air conditionné et la réfrigération - Partie 2: Tubes pour le matériel

La présente Norme européenne spécifie les exigences, le mode d'échantillonnage, les méthodes d'essai et les conditions de livraison applicables aux tubes ronds sans soudure en cuivre à intérieur lisse ou rainuré, utilisés pour les échangeurs thermiques et leurs raccordements intérieurs dans la fabrication des matériels de réfrigération et de conditionnement d'air.
Elle s’applique aux tubes ayant un diamètre extérieur de 3,97 mm à 219 mm inclus.
NOTE   Ces tubes sont livrés en longueurs droites à l'état dur, demi-dur ou écroui en surface ou bien en couronnes à l'état recuit (1/4 dur ou recuit).

Baker in bakrove zlitine - Nevarjene okrogle bakrene cevi za hladilno in klimatsko tehniko - 2. del: Cevi za naprave in aparate

Ta evropski standard določa zahteve, postopek vzorčenja, preskusne metode in pogoje za dobavo nevarjenih okroglih bakrenih cevi, gladkih ali notranje orebrenih, ki se uporabljajo za toplotne prenosnike, ter njihove notranje priključene cevi v proizvodnji hladilne in klimatske opreme.
Uporablja se tudi za cevi z zunanjim premerom od 3,97 mm do vključno 219 mm.
Cevi so dobavljene v ravnih presekih v trdem, poltrdem ali površinsko ojačanem stanju ali v navojih v svetlo žarjenem ali mehko žarjenem stanju.
