EN ISO 3452-1:2021

Non-destructive testing - Penetrant testing - Part 1: General principles (ISO 3452-1:2021)

This document specifies a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and lack of fusion, which are open to the surface of the material to be tested using white light or UV-A (365 nm) radiation. It is mainly applied to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and not excessively porous (castings, forgings, welds, ceramics, etc.)
This document also includes requirements for process and control testing, but is not intended to be used for acceptance criteria. It gives neither information relating to the suitability of individual test systems for specific applications nor requirements for test equipment.
NOTE 1   Methods for determining and monitoring the essential properties of penetrant testing products to be used are specified in ISO 3452-2 and ISO 3452-3.
NOTE 2   The term "discontinuity" is used in this document in the sense that no evaluation concerning acceptability or non-acceptability is included.
NOTE 3   CEN/TR 16638 addresses penetrant testing using actinic blue light.

Zerstörungsfreie Prüfung - Eindringprüfung - Teil 1: Allgemeine Grundlagen (ISO 3452-1:2021)

Dieses Dokument legt ein Verfahren mit Weißlicht oder UV A Strahlung (365 nm) für die Eindringprüfung zum Auffinden von Fehlern wie z. B. Rissen, Überlappungen, Falten, Poren und Bindefehlern fest, die zur Oberfläche des zu prüfenden Werkstoffs hin offen sind. Es wird vorwiegend bei metallischen Werkstoffen angewendet, kann jedoch auch bei anderen Werkstoffen eingesetzt werden, vorausgesetzt, diese Werkstoffe sind gegenüber den Prüfmitteln inert und nicht übermäßig porös (Guss  und Schmiedestücke, Schweißnähte, Keramik usw.).
Dieses Dokument enthält außerdem die Anforderungen an Prozess  und Kontrollprüfungen, ist jedoch nicht für die Anwendung von Annahmekriterien vorgesehen. Es enthält weder Angaben bezüglich der Eignung der einzelnen Prüfsysteme für spezielle Anwendungen noch Anforderungen an die Prüfgeräte.
ANMERKUNG 1   Die Verfahren zur Bestimmung und Darstellung der wesentlichen Eigenschaften der verwendeten Eindringprüfmittel sind in ISO 3452 2 und ISO 3452 3 festgelegt.
ANMERKUNG 2   Der Begriff „Fehler“ wird in diesem Dokument in dem Sinne verwendet, dass keine Bewertung im Hinblick auf Zulässigkeit oder Unzulässigkeit eingeschlossen ist.
ANMERKUNG 3   CEN/TR 16638 behandelt die Eindringprüfung mit aktinischem Blaulicht

Essais non destructifs - Examen par ressuage - Partie 1: Principes généraux (ISO 3452-1:2021)

Le présent document spécifie une méthode d’examen par ressuage utilisée pour localiser des discontinuités, telles que fissures, replis, plis, porosités et manque de liaison, ouvertes et débouchant à la surface du matériau à examiner, à l’aide d’une lumière blanche ou d’un rayonnement UV-A (365 nm). Cette méthode est principalement appliquée aux matériaux métalliques mais peut également être utilisée pour d’autres matériaux, à condition que ces derniers ne soient pas attaqués par les produits utilisés et ne soient pas excessivement poreux (pièces moulées ou forgées, soudures, céramiques, etc.).
Le présent document comprend également les exigences applicables aux essais de processus et de contrôle, mais ne définit pas de critères d’acceptation. Il ne donne ni information relative à l’aptitude à l’emploi de systèmes de ressuage spécifiques à des applications particulières, ni exigences relatives à l’équipement d’essai.
NOTE 1      Les méthodes de détermination et de contrôle des propriétés principales des produits de ressuage à utiliser sont spécifiées dans l’ISO 3452‑2 et l’ISO 3452‑3.
NOTE 2      Dans le présent document, le terme «discontinuité» ne sous-entend aucune évaluation en matière d’acceptabilité ou de non-acceptabilité.
NOTE 3      Les examens par ressuage à la lumière bleue actinique sont abordés par le rapport technique CEN/TR 16638.
