Zerstörungsfreie Prüfung von Schweißverbindungen - Zulässigkeitsgrenzen für die Durchstrahlungsprüfung - Teil 2: Aluminium und seine Legierungen (ISO/DIS 10675-2:2021)

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. In diesem Dokument wird davon ausgegangen, dass die Durchstrahlungsprüfung nach ISO 17636-1 für RT-F (F = Film) oder ISO 17636-2 für RT-S (S = Radioskopie) und RT-D (D = digitale Detektoren) durchgeführt wurde.
Wenn untersucht wird, ob eine Schweißnaht die Anforderungen an eine Schweißnahtbewertungsgruppe erfüllt, werden die nach den Normen erlaubten Größen der Unregelmäßigkeiten mit den Abmessungen der Anzeigen verglichen, die auf der von der Schweißnaht gemachten Durchstrahlungsaufnahme gefunden wurden.

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.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

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 www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,

Subcommittee SC 5, Testing and inspection of welds, WG1.

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:
— the document was technically and editorially revised;
— in Clause 4 the normative references of Table 1 and Table 2 were corrected;

— in Table 3 Acceptance levels for internal indications in butt welds No 3 and No 4: acceptance levels

for maximum permissible pore sizes for clustered and linear porosity were added;
— in Annex B the capture of Figure B.1 was revised;

— in Annex C Figures C.1, C.2 and the text were revised to be conform to the ISO 10042:2018.

A list of all parts of the ISO 10675 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A

DRAFT INTERNATIONAL STANDARD ISO/DIS 10675-2:2021(E)
Non-destructive testing of welds — Acceptance levels for
radiographic testing —
Part 2:
Aluminium and its alloys
1 Scope

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).

When assessing whether a weld meets the requirements specified for a weld quality level, the sizes of

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

radiograph made of the weld.

4 Radiographic technique

Depending on the weld quality level, radiographic technique A or B in accordance with ISO 17636-1 shall

be used for RT-F as shown in Table 1 and radiographic technique A or B in accordance with ISO 17636-2

shall be used for RT-S or RT-D as shown in Table 2.
