标准简介
OVERVIEW中文简介
该标准规定了使用X射线和伽马射线对金属材料进行射线照相检测的基本原则。它旨在确保检测结果具有足够的灵敏度和可比性,同时保持经济性。标准涵盖了检测技术的分类(A类和B类)、推荐的操作程序以及测试报告的要求。
English summary
This standard lays down the basic rules for the radiographic examination of metallic materials using X-rays and gamma-rays. It aims to ensure sufficient and comparable results in an economical manner. The document covers the classification of radiographic techniques (Class A and Class B), recommended procedures for taking radiographs, and requirements for test reports.

DOCUMENT PREVIEW6.2.2 Andere Strahlenquellen
Zulässige Bereiche der durchstrahlten Dicke für Gammastrahler und Röntgenstrahler über 1 MeV sind in Tabelle 1 angegeben.

|
Tabelle 1: Dickenbereich des Prüfgegenstandes für Gammastrahler und für Röntgenstrahler ab 1 MeV Grenzenergie für Stahl, Kupfer und Nickel-Basislegierungen
|
Bei Prüfgegenständen aus dünnwandigem Stahl erzeugen Gammastrahlen von Ir 192 und Co 60 keine Durchstrahlungsaufnahmen mit einer ebenso guten Fehlerauffindbarkeit wie solche, die durch Anwendung von Röntgenstrahlen mit geeigneter Technik gemacht wurden. Wegen der Vorteile von Gammastrahlenquellen bezüglich Handhabbarkeit und Zugänglichkeit gibt Tabelle 1 jedoch einen Dickenbereich für jede dieser γ-Strahlenquellen, der angewendet werden darf, wenn die Anwendung von Röntgenstrahlen nicht möglich ist. Für bestimmte Anwendungen dürfen größere Wanddickenbereiche erlaubt werden, wenn ausreichende Bildqualität erreicht werden kann. In den Fällen, wo Durchstrahlungsbilder mit Gammastrahlen erzeugt werden, darf die Zeit zur Positionierung der Quelle 10% der gesamten Belichtungszeit nicht überschreiten. 6.3 Filmsysteme und Aufnahme folienFür die Durchstrahlungsprüfung sind Filmsystemklassen nach EN 584-1 zu verwenden. Für verschiedene Strahlenquellen werden die minimalen Filmsystemklassen in den Tabellen 2 und 3 angegeben. Wenn Aufnahmefolien verwendet werden, muß ein guter Kontakt zwischen Film und Folie erzielt werden. Dies kann entweder durch Verwendung von vakuumverpackten Filmen oder durch Anpreßdruck erreicht werden. Für die verschiedenen Strahlenquellen werden in den Tabellen 2 und 3 die empfohlenen Aufnahmefolien angegeben. Andere Aufnahmefoliendicken dürfen zwischen den Vertragspartnern auch vereinbart werden, vorausgesetzt, die geforderte Bildgüte wird erreicht. |
