Full title and description

Non‑destructive testing of welds — Acceptance levels for radiographic testing — Part 1: Steel, nickel, titanium and their alloys. This is the ISO international standard that defines acceptance criteria for indications (imperfections) detected by radiographic testing in butt welds of these metallic materials; a Russian‑language edition/translation is also available as a supplied product (designation "St ISO 10675-1-2021 rus").

Abstract

This document specifies acceptance levels for indications from imperfections in butt welds of steel, nickel, titanium and their alloys as detected by radiographic testing. Where agreed between parties, the acceptance levels may be applied to other weld types (for example fillet welds) or to other materials. The standard assumes radiographic testing has been carried out in accordance with ISO 17636‑1 (film) or ISO 17636‑2 (radioscopy / digital detectors).

Scope

Defines acceptance levels (criteria) for radiographic indications in butt welds of steel, nickel, titanium and their alloys. The acceptance levels are intended to be referenced by welding standards, application standards, specifications or codes and assume radiographic examination performed per ISO 17636‑1 (RT‑F) or ISO 17636‑2 (RT‑S, RT‑D). The rules may be applied to other weld types or materials when mutually agreed.

Key topics and requirements

• Acceptance levels for radiographic indications in butt welds of steel, nickel, titanium and their alloys (classification of acceptable/unacceptable indications).
• Correlation of radiographic indication size/shape with permissible imperfection sizes given in welding/application standards.
• Application guidance for film radiography (RT‑F) and digital/radioscopic techniques (RT‑S, RT‑D) in conjunction with ISO 17636 series.
• Allowing contractual agreement to extend acceptance levels to other weld types (e.g., fillet welds) or materials.
• Intended use as a reference for inspection acceptance criteria in fabrication, code compliance and quality control.

Typical use and users

Used by nondestructive testing (NDT) engineers and technicians, welding engineers, quality assurance / quality control personnel, third‑party inspectors, fabrication shops and code authorities who specify or verify radiographic acceptance criteria for welded joints in steel, nickel, titanium and their alloys. The standard is referenced where formal radiographic acceptance levels are required.

Related standards

ISO 10675 is a multipart publication; Part 2 covers aluminium and its alloys (ISO 10675‑2:2021). Radiographic practice and detector guidance are given in the ISO 17636 series (ISO 17636‑1 and ISO 17636‑2), which ISO 10675 references for test execution (film, radioscopy and digital detectors). These documents are commonly used together when specifying and carrying out radiographic weld inspection.

FAQ

Q: What is this standard?

A: ISO 10675‑1:2021 specifies acceptance levels for indications from imperfections in butt welds of steel, nickel, titanium and their alloys detected by radiographic testing.

Q: What does it cover?

A: It provides criteria to assess radiographic indications (size/shape) against permissible imperfection sizes from welding or application standards, and assumes radiographic testing is performed per ISO 17636‑1 or ISO 17636‑2. It also allows contractual application to other weld types or materials.

Q: Who typically uses it?

A: NDT personnel, weld inspectors, welding engineers, fabricators, QA/QC teams and regulatory/code bodies that require established radiographic acceptance criteria.

Q: Is it current or superseded?

A: The current published edition is ISO 10675‑1:2021 (edition 3, published December 2021), which revises and replaces previous editions (for example the 2016 edition).

Q: Is it part of a series?

A: Yes — ISO 10675 is published in at least two parts: Part 1 (steel, nickel, titanium and their alloys) and Part 2 (aluminium and its alloys, ISO 10675‑2:2021). It is also intended to be used alongside the ISO 17636 series that covers radiographic testing techniques.

Q: What are the key keywords?

A: Radiographic testing, weld acceptance levels, butt welds, NDT, ISO 10675, ISO 17636, steel, nickel, titanium, alloys, RT‑F, RT‑S, RT‑D.
