Zerstörungsfreie Prüfung von Schweißverbindungen - Zulässigkeitsgrenzen für die Durchstrahlungsprüfung - Teil 1: Stahl, Nickel, Titan und deren Legierungen (ISO/DIS 10675-1:2021)

Dieses Dokument legt für die Durchstrahlungsprüfung die Zulässigkeitsgrenzen für Anzeigen von Unregel-mäßigkeiten von Stumpfschweißnähten in Stahl, Nickel, Titan und deren Legierungen fest. Falls vereinbart, können die Zulässigkeitsgrenzen auf andere Arten von Schweißnähten (wie 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 nach ISO 17636-1 für RT-F (F = mit Filmen) oder ISO 17636-2 für RT-S (S = Radioskopie) und RT-D (D = mit digitalen Detektoren) durchgeführt wurde.
Bei der Bewertung, ob eine Schweißnaht die Anforderungen an eine Schweißnahtbewertungsgruppe erfüllt, werden die nach den Normen zulässigen Größen der Unregelmäßigkeiten mit den Abmessungen der Anzeigen verglichen, die auf der von der Schweißnaht angefertigten Durchstrahlungsaufnahme nachgewiesen werden.

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

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

Subcommittee SC 5, Testing and inspection of welds.

This third edition cancels and replaces the second edition (ISO 10675-1:2016), which has been

technically revised.
The main changes compared to the previous edition are as follows:
— The document has been technically and editorial revised;
— Clause 4 Radiographic technique has been technically revised;
— Clause 5 General has been added;
— The acceptance levels in clause 6 have been extended;

— Table 1- Radiographic testing was split into Table 1- Radiographic testing for RT-F and Table 2 –

Radiographic testing for RT-S and RT-D;

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

maximum permissible pore sizes 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 ISO 5817:2014.

Non-destructive testing of welds — Acceptance levels for
radiographic testing —
Part 1:
Steel, nickel, titanium and their alloys
1 Scope

This document specifies acceptance levels for indications from imperfections in butt welds of steel,

nickel, titanium and their alloys 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.

However, the minimum number of exposure for circumferential weld testing may correspond to the requirements of

5 General

Welded joints should be visually tested in accordance with ISO 17637 and evaluated before radiographic

testing.

The acceptance levels of this document are basically valid for evaluation of imperfections which cannot

be detected and evaluated by visual testing (see Table 3). Surface imperfections (see Table 4; such as

undercut and excessive penetration, surface damage, weld spatter, etc.) which, due to object geometry,

cannot be evaluated by visual testing, but where the interpreter suspects that the ISO 5817 quality

levels are not fulfilled, shall be subject to more specific testing for quantification.

When quantification of undercut and/or excessive penetration by radiographic testing is required,

specific procedures using test exposures may be applied in order to establish a basis for approximate

quantif
