Brazing - Non-destructive examination of brazed joints
This European Standard describes non-destructive examination procedures and test piece types necessary to perform the tests on brazed joints. The non-destructive examination methods described are as follows: a) visual examination (see clause 4); b) ultrasonic examination (see clause 5); c) radiographic examination (see clause 6); d) penetrant examination (see clause 7); e) leak testing (see clause 8); f) proof testing (see clause 9); g) thermography (see clause 10). The brazed joints to which these tests are applied can either be test samples manufactured to obtain brazed joint design data, or manufactured as part of the approval testing of a brazing procedure, or parts of a brazed assembly. The type of test piece described for each test can be quoted or incorporated in engineering application standards that deal with brazed assemblies. This European Standard does not recommend the number of samples to be tested or the repeat tests allowed. Neither does it specify methods of sampling brazed joints, except to give guidance regarding the precautions necessary, nor does it comment on the acceptance criteria applicable to any of the tests. No attempt is made to define which test or tests, if any , should be applied in any situation. This is a matter to be established before any particular method of test is selected. The methods of non-destructive examination are not associated with any particular type of brazed assembly but lay down the general principles of the types of testing described. It is emphasised that a satisfactory examination method can only be developed and used after taking into account all the relevant factors regarding the equipment to be used and the characteristics of the test piece being examined.
Hartlöten - Zerstörungsfreie Prüfung von Hartlötverbindungen
Diese Europäische Norm beschreibt zerstörungsfreie Prüfverfahren und Prüfstückarten, die zur Durchführung von Prüfungen an Hartlötverbindungen notwendig sind. Die folgenden zerstörungsfreien Prüfverfahren sind beschrieben: a) Sichtprüfung (siehe Abschnitt 4); b) Ultraschallprüfung (siehe Abschnitt 5); c) Durchstrahlungsprüfung (siehe Abschnitt 6); d) Eindringprüfung (siehe Abschnitt 7);
e) Dichtheitsprüfung (siehe Abschnitt 8); f) Überdruckprüfung (siehe Abschnitt 9); g) Thermographie (siehe Abschnitt 10). Die Hartlötverbindungen, an denen diese Prüfungen durchgeführt werden, können entweder als Prüfstück hergestellt sein, um für Hartlötverbindungen Konstruktionsdaten zu ermitteln, oder Teil einer Hartlötkonstruktion sein. Auf die Art des Prüfstücks, das für jede Prüfung beschrieben wird, kann Bezug genommen werden, oder wird in den technischen Anwendungsnormen, die sich auf die Hartlötkonstruktionen beziehen, eingearbeitet. Diese Europäische Norm empfiehlt nicht die Anzahl der zu untersuchenden Prüfstücke oder der zulässigen Wiederholungsprüfungen festzulegen. Sie legt bis auf einen aufgeführten Leitfaden bezüglich der notwendigen
Vorsichtsmaßnahmen weder die Art der Probenahme aus den hartgelöteten Verbindungen fest, noch erläutert sie die Bewertungsmerkmale, die für jede der Prüfungen anzuwenden sind. Es wurde kein Versuch unternommen, festzulegen, welche Prüfung oder Prüfungen in welcher Situation angewendet werden sollten. Dies ist, bevor eine spezielle Prüfmethode ausgewalht wird, zu vereinbaren. Die Verfahren der zerstörungsfreien Prüfung beziehen sich nicht auf eine bestimmte Art hartgelöteter Konstruktionen, sie legen jedoch die allgemeinen Grundsätze der beschriebenen Prüfungsarten fest...(Abgeschnitten)
