Copper and copper alloys - Eddy current test for measuring defects on seamless round copper and copper alloy tubes - Part 2: Test with an internal test coil on the inner surface

This part of this European Standard specifies a procedure for the eddy current test with an internal test coil for measuring defects on the inner surface of seamless round copper and copper alloy tubes. The eddy current test method(s) required, together with the size range and acceptance level, are defined in the relevant product standard. The choice of the method for eddy current test:
- with an encircling test coil on the outer surface according EN 1971-1; or
- with an internal test coil on the inner surface according EN 1971-2;
is at the discretion of the manufacturer if there are no other agreements between the purchaser and the supplier. Especially for finned tubes according to EN 12452 with high fins it is recommended to use eddy current test with internal sensor as described in this standard.

Diese Europäische Norm legt ein Verfahren für die Wirbelstromprüfung von nahtlosen runden Rohren aus Kupfer und Kupferlegierungen mit Innensonde auf der Innenoberfläche fest. Diese Europäische Norm gilt insbesondere für Rippenrohre mit hohen Rippen nach EN 12452. ANMERKUNG Das(Die) geforderte(n) Wirbelstromprüfverfahren sowie der Maßbereich und die Sortiergrenze sind in der entsprechenden Produktnorm festgelegt. Die Wahl des Verfahrens für die Wirbelstromprüfung mit
- umfassender Spule auf der Außenseite nach EN 1971-1; oder
- Innensonde auf der Innenseite nach EN 1971-2; obliegt dem Hersteller, wenn keine anderen Vereinbarungen zwischen Hersteller und Lieferer getroffen wurden. Besonders für Rippenrohre mit hohen Rippen nach EN 12452, wird die Anwendung der Wirbelstromprüfung mit Innensonde, wie in dieser Norm beschrieben, empfohlen.

Cuivre et alliages de cuivre - Méthode de contrôle par courants de Foucault pour le mesurage des défauts des tubes ronds sans soudure en cuivre et alliages de cuivre - Partie 2: Essai avec une bobine interne sur la paroi interne

La présente Norme européenne spécifie un mode opératoire relatif au contrôle par courants de Foucault pour

Baker in bakrove zlitine - Metoda preskušanja z vrtinčnimi tokovi za merjenje napak na nevarjenih okroglih ceveh iz bakra in bakrovih zlitin - 2. del: Preskus z notranjo preskusno tuljavo ob notranji površini

Ta del tega evropskega standarda določa postopek za metodo preskušanja z vrtinčnimi tokovi z notranjo preskusno tuljavo za merjenje napak ob notranji površini nevarjenih okroglih cevi iz bakra in bakrovih zlitin. Zahtevane metode preskušanja z vrtinčnimi tokovi ter razpon velikosti in meja sprejemljivosti so določeni v ustreznem standardu za izdelek. Metodo za preskušanje z vrtinčnimi tokovi:
– s preskusno tuljavo, ki obdaja zunanjo površino, v skladu s standardom EN 1971-1; ali
– z notranjo preskusno tuljavo ob notranji površini v skladu s standardom EN 1971-2;
izbere proizvajalec, če ne obstaja drugačen dogovor med kupcem in dobaviteljem.
Preskušanje z vrtinčnimi tokovi z notranjim senzorjem v skladu s tem standardom je priporočeno zlasti za narebričene cevi iz standarda EN 12452 z visokimi rebri..

EN 1971-2:2011 (E) 4 Introduction The eddy current test with internal probe described in this standard has the objective of detecting potential leaks and serious defects in seamless round copper and copper alloy tubes. The eddy current test is able to detect material inhomogeneities and their positions throughout the length of tubes. The eddy current signals of material inhomogeneities are compared with reference signals of artificially produced test defects. It is possible to identify these inhomogeneities on the inner and outer surfaces as well as wi
