Non-destructive testing of welds - Acceptance levels for radiographic testing - Part 2: Aluminium and its alloys (ISO 10675-2:2021, Corrected version 2022-02)

This document specifies acceptance levels for indications from imperfections in aluminium butt welds detected by radiographic testing. If agreed, the acceptance levels can be applied to other types of welds (such as fillet welds etc.) or materials.
The acceptance levels can be related to welding standards, application standards, specifications or codes. This document assumes that the radiographic testing has been carried out in accordance with ISO 17636‑1 for RT-F (F = film) or ISO 17636‑2 for RT-S (S = radioscopy) and RT-D (D = digital detectors).

Zerstörungsfreie Prüfung von Schweißverbindungen - Zulässigkeitsgrenzen für die Durchstrahlungsprüfung - Teil 2: Aluminium und seine Legierungen (ISO 10675-2:2021, korrigierte Fassung 2022-02)

Dieses Dokument legt für die Durchstrahlungsprüfung die Zulässigkeitsgrenzen für Anzeigen von Unregelmäßigkeiten von Stumpfschweißnähten in Aluminium und seinen Legierungen fest. Falls vereinbart, können die Zulässigkeitsgrenzen auf andere Arten von Schweißnähten (z. B. Kehlnähte usw.) oder andere Werkstoffe angewendet werden.
Die Zulässigkeitsgrenzen können sich auf Schweißnormen, Anwendungsnormen, Spezifikationen oder Codes beziehen. Dieses Dokument geht davon aus, dass die Durchstrahlungsprüfung für RT F (F = mit Filmen) nach ISO 17636 1 oder für RT S (S = Radioskopie) und RT D (D = mit digitalen Detektoren) nach ISO 17636 2 durchgeführt wurde.

Essais non destructifs des assemblages soudés - Niveaux d'acceptation pour évaluation par radiographie - Partie 2: Aluminium et ses alliages (ISO 10675-2:2021, Version corrigée 2022-02)

Le présent document spécifie les niveaux d'acceptation des indications des défauts présents dans les assemblages soudés bout à bout en aluminium détectés par contrôle radiographique. En fonction des accords passés, les niveaux d'acceptation peuvent être appliqués à d'autres types d'assemblages soudés (tels que les soudures d’angle, etc.) ou matériaux.
Les niveaux d'acceptation peuvent être reliés à des normes de soudage, des normes d'application, des spécifications ou des codes. Le présent document présume que le contrôle par radiographie a été exécuté conformément à l'ISO 17636‑1 pour les essais par radiographie en utilisant des films (RT-F) ou à l’ISO 17636‑2 pour les essais de radioscopie (RT-S) et les essais par radiographie numérique (RT-D).

Neporušitveno preskušanje zvarnih spojev - Stopnje sprejemljivosti pri radiografskem preskušanju - 2. del: Aluminij in njegove zlitine (ISO 10675-2:2021)

Ta dokument določa stopnje sprejemljivosti za označevanje na podlagi nepravilnosti v aluminijevih soležnih zvarih, ki se zaznajo z radiografskim preskušanjem. V primeru dogovora je mogoče stopnje sprejemljivosti uporabiti za druge vrste zvarov (npr. kotne zvare itd.) ali materialov. Stopnje sprejemljivosti se lahko navezujejo na standarde varjenja, standarde uporabe, specifikacije ali oznake. V tem dokumentu je predpostavljeno, da je bilo radiografsko preskušanje izvedeno skladno s standardom ISO 17636-1 za RT-F (F = film) ali ISO 17636-2 za RT-S (S = radioskopija) in RT-D (D = digitalni detektorji).

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This third edition cancels and replaces the second edition (ISO 10675-2:2017), which has been

technically revised.
The main changes compared to the previous edition are as follows:
— new Table 1 added with abbreviations;

— in Table 4 (former Table 3), acceptance levels for maximum permissible pore sizes of porosity,

clustered porosity, linear porosity, elongated cavities and for lack of fusion have been added;

— the acceptance levels in Clause 6 have been extended (General and tables);
— the capture of Figure B.1 has been revised to conform with ISO 10042:2018;

— Figures C.1, C.2 and the text have been revised to conform with ISO 10042:2018.

— the document has been editorially revised.

imperfections permitted by standards are compared with the dimensions of indications revealed by a

radiograph made of the weld.
