Non-destructive testing of welds - Radiographic testing - Part 1: X- and gamma-ray techniques with film (ISO 17636-1:2022)
This document specifies techniques of radiographic testing of fusion-welded joints in metallic materials using industrial radiographic film techniques with the object of enabling satisfactory and repeatable results. The techniques are based on generally recognized practice and fundamental theory of the subject.
It applies to the joints of plates and pipes in metallic materials. 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 does not specify acceptance levels for any of the indications found on the radiographs. The ISO 10675 series provides information on acceptance levels for weld evaluation.
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 1: Röntgen- und Gammastrahlungstechniken mit Filmen (ISO 17636-1:2022)
Dieses Dokument legt Techniken der Durchstrahlungsprüfung von Schmelzschweißverbindungen in metallischen Werkstoffen unter Anwendung von Techniken mit industriellen radiographischen Filmen mit dem Ziel, zufriedenstellende und wiederholbare Ergebnisse zu erhalten, fest. Die Techniken beruhen auf allgemein anerkannten Vorgehensweisen und den grundlegenden Theorien zum Thema.
Dieses Dokument gilt für Schweißverbindungen von Platten und Rohren aus metallischen Werkstoffen. Neben der konventionellen Bedeutung umfasst der Begriff „Rohr“ in diesem Dokument auch andere zylindrische Körper wie Druckleitungen, Kesseltrommeln und Druckbehälter.
Dieses Dokument legt keine Zulässigkeitsgrenzen für Anzeigen in den Durchstrahlungsaufnahmen fest. Die Normenreihe ISO 10675 enthält Informationen zu Zulässigkeitsgrenzen für die Untersuchung von Schweißnähten.
Wenn die Vertragspartner niedrigere Prüfkriterien verwenden, kann die erreichte Güte deutlich niedriger sein als bei strikter Anwendung dieses Dokuments.
Essais non destructifs des assemblages soudés - Contrôle par radiographie - Partie 1: Techniques par rayons X ou gamma à l'aide de film (ISO 17636-1:2022)
Le présent document spécifie des techniques de contrôle par radiographie des assemblages soudés par fusion de matériaux métalliques en utilisant des techniques employant un film pour radiographie industrielle, dans le but d'obtenir des résultats satisfaisants et reproductibles. Les techniques reposent sur une pratique généralement reconnue et sur la théorie fondamentale en la matière.
Il est applicable aux assemblages de plaques et de tubes dans les matériaux métalliques. 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 ne spécifie pas les niveaux d'acceptation des indications trouvées sur les radiogrammes. La série des 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 - 1. del: Tehnike z rentgenskimi in gama žarki z uporabo filmov (ISO 17636-1:2022)
Ta dokument določa tehnike radiografskega preskušanja talilno zvarjenih spojev kovinskih materialov s tehnikami industrijskega radiografskega filma z namenom omogočanja zadovoljivih in ponovljivih rezultatov. Tehnike so osnovane na splošno priznani praksi in temeljnem poznavanju subjekta.
Uporablja se za spoje plošč in cevi kovinskih materialov. 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 ne določa stopenj sprejemljivosti za indikacije na rentgenskih slikah. Skupina standardov ISO 10675 podaja informacije o stopnjah sprejemljivosti za ocenjevanje zvarnih spojev.
Če pogodbene stranke uporabijo nizka preskusna merila, bo dosežena kakovost morda znatno nižja od kakovosti, dosežene s strogim upoštevanjem tega dokumenta.
