Non-destructive testing of welds - Radiographic testing - Part 2: X- and gamma-ray techniques with digital detectors (ISO 17636-2:2022)
This document specifies techniques of digital radiography with the object of enabling satisfactory and repeatable results. The techniques are based on generally recognized practice and fundamental theory of the subject.
This document applies to the digital radiographic testing of fusion welded joints in metallic materials. It applies to the joints of plates and pipes. Besides its conventional meaning, “pipe”, as used in this document, covers other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels.
This document specifies the requirements for digital radiographic X- and gamma-ray testing by either computed radiography (CR) or radiography with digital detector arrays (DDAs) of the welded joints of metallic plates and tubes for the detection of imperfections. It includes manual and automated inspection with DDAs.
Digital detectors provide a digital grey value image which can be viewed and evaluated using a computer (Annex E). This document specifies the recommended procedure for detector selection and radiographic practice. Selection of computer, software, monitor, printer and viewing conditions are important, but are not the main focus of this document. The procedure specified in this document provides the minimum requirements for radiographic practice which permits exposure and acquisition of digital radiographs with equivalent sensitivity for the detection of imperfections as film radiography (specified in ISO 17636-1).
This document does not specify acceptance levels for any of the indications found on the digital radiographs. ISO 10675 provides information on acceptance levels for weld inspection.
If contracting parties apply lower test criteria, it is possible that the quality achieved will be significantly lower than when this document is strictly applied.
Zerstörungsfreie Prüfung von Schweißverbindungen - Durchstrahlungsprüfung - Teil 2: Röntgen- und Gammastrahlungstechniken mit digitalen Detektoren (ISO 17636-2:2022)
Dieses Dokument legt Techniken der digitalen Durchstrahlungsprüfung mit dem Ziel fest, zufriedenstellende und wiederholbare Ergebnisse zu erreichen. Die Techniken beruhen auf allgemein anerkannten Vorgehensweisen und den grundlegenden Theorien zum Thema.
Dieses Dokument ist anwendbar für die digitale Durchstrahlungsprüfung von Schmelzschweißverbindungen in metallischen Werkstoffen. Es ist anwendbar für Schweißverbindungen von Platten und Rohren. Neben der konventionellen Bedeutung werden in diesem Dokument unter der Benennung „Rohr“ auch andere zylindrische Körper wie Druckleitungen, Kesseltrommeln und Druckbehälter verstanden.
Dieses Dokument legt die Anforderungen an die digitale Durchstrahlungsprüfung von Schweißverbindungen an Metallplatten und -rohren mit Röntgen- und Gammastrahlen unter Anwendung entweder der Computer-Radiographie (CR) oder der Radiographie mit digitalen Matrixdetektoren (DDA, en: Digital Detector Arrays) fest, die dem Nachweis von Unregelmäßigkeiten dient. Es umfasst die manuelle und automatische Prüfung mittels DDA.
Digitale Detektoren liefern ein Bild mit digitalen Grauwerten, das mit einem Computer betrachtet und ausgewertet werden kann (Anhang E). Dieses Dokument legt die empfohlenen Verfahren für die Auswahl des Detektors und der Durchstrahlungstechnik fest. Die Auswahl von Computer, Software, Monitor, Drucker und Betrachtungsbedingungen ist von Bedeutung, bildet jedoch nicht den Schwerpunkt dieses Dokuments. Das in diesem Dokument festgelegte Verfahren enthält die Mindestanforderungen an das Durchstrahlungsverfahren zur Gewinnung digitaler Durchstrahlungsaufnahmen mit einer Empfindlichkeit für den Nachweis von Unregelmäßigkeiten, die der Radiographie mit Filmen (festgelegt in ISO 17636 1) gleichwertig ist.
Dieses Dokument legt keine Zulässigkeitsgrenzen für Anzeigen in den digitalen Durchstrahlungsaufnahmen fest. ISO 10675 enthält Informationen über Zulässigkeitsgrenzen bei der Prüfung von Schweißnähten (Schweißverbindungen).
Wenn die Vertragspartner niedrigere Prüfkriterien verwenden, ist es möglich, dass die erreichte Güte deutlich niedriger ist als bei strikter Anwendung von diesem Dokument.
Essais non destructifs des assemblages soudés - Contrôle par radiographie - Partie 2: Techniques par rayons X ou gamma à l'aide de détecteurs numériques (ISO 17636-2:2022)
Le présent document spécifie les techniques de radiographie numérique permettant d'obtenir des résultats satisfaisants et reproductibles. Les techniques reposent sur une pratique généralement reconnue et sur la théorie fondamentale en la matière.
Le présent document s'applique au contrôle par radiographie numérique des assemblages soudés par fusion de matériaux métalliques. Il s'applique aux assemblages de plaques et de tubes. Outre sa signification conventionnelle, le terme « tube », tel qu'il est utilisé dans le présent document, couvre d'autres corps cylindriques, tels que tuyaux, conduites forcées, réservoirs de chaudières et appareils à pression.
Le présent document spécifie les exigences relatives au contrôle par radiographie numérique à rayons X et gamma des assemblages soudés de tubes métalliques pour la détection des imperfections, soit par radiographie numérique (CR), soit par radiographie avec des panneaux de détecteurs numériques (DDA). Il comprend un contrôle manuel et automatisé avec des DDA.
Les détecteurs numériques produisent une image numérique en valeurs de gris qui ne peut être visualisée et évaluée qu'à l'aide d'un ordinateur (Annexe E). Le présent document spécifie le mode opératoire recommandé pour le choix des détecteurs et la pratique radiographique. Le choix de l'ordinateur, du logiciel, de l'écran, de l'imprimante et des conditions d'observation est important, mais ne constitue pas le centre d'intérêt du présent document. Le mode opératoire spécifié dans le présent document fournit les exigences minimales pour la pratique radiographique permettant l'exposition et l'acquisition des radiogrammes numériques avec une sensibilité de détection des imperfections équivalente à celle de la radiographie à l'aide de film (spécifiée dans l'ISO 17636‑1).
Le présent document ne spécifie pas les niveaux d'acceptation des indications trouvées sur les radiogrammes numériques. L'ISO 10675 fournit des informations sur les niveaux d'acceptation pour le contrôle des soudures.
Si les parties contractantes appliquent des critères d'essai moins rigoureux, il se peut que la qualité obtenue soit nettement inférieure à celle atteinte par l'application stricte du présent document.
Neporušitveno preskušanje zvarnih spojev - Radiografsko preskušanje - 2. del: Tehnike z rentgenskimi in gama žarki z uporabo digitalnih detektorjev (ISO 17636-2:2022)
Ta dokument določa tehnike digitalne radiografije z namenom omogočanja zadovoljivih in ponovljivih rezultatov. Tehnike so osnovane na splošno priznani praksi in temeljnem poznavanju subjekta.
Ta dokument se uporablja za digitalno radiografsko preskušanje talilno zvarjenih spojev v kovinskih materialih. Uporablja se za spoje plošč in cevi. Poleg svojega klasičnega pomena izraz »cev«, kot je uporabljen v tem dokumentu, zajema tudi druga cilindrična telesa, kot so dovodni kanali, bobni kotlov in tlačne posode.
Ta dokument določa zahteve za zaznavanje nepravilnosti zvarjenih spojev pri kovinskih ploščah in ceveh z digitalnim radiografskim preskušanjem z rentgenskimi ali gama žarki z uporabo računalniške radiografije (CR) ali radiografije z digitalnimi detektorskimi nizi (DDA). Vključuje ročni in avtomatizirani pregled z digitalnimi detektorskimi nizi.
Digitalni detektorji zagotavljajo digitalno sivinsko sliko, ki jo je mogoče prikazati in oceniti prek računalnika (dodatek E). Ta dokument določa priporočen postopek za izbiro detektorja in radiografsko prakso. Izbira računalnika, programske opreme, monitorja, tiskalnika in pogojev prikaza je pomembna, vendar ni ključni del tega dokumenta. Postopek, določen v tem dokumentu, zagotavlja minimalne zahteve za radiografsko prakso, ki omogočajo izpostavljenost in pridobivanje digitalnih rentgenskih slik z občutljivostjo zaznavanja nepravilnosti, enako kot pri radiografskem filmu (iz standarda ISO 17636-1).
Ta dokument ne določa stopenj sprejemljivosti za indikacije na digitalnih rentgenskih slikah. Standard ISO 10675 podaja informacije o stopnjah sprejemljivosti za pregled zvarnih spojev.
Če pogodbene stranke uporabijo nizka preskusna merila, bo dosežena kakovost morda znatno nižja od kakovosti, dosežene s strogim upoštevanjem tega dokumenta.
