ISO 9017-2017 PDF

Full title and description

Destructive tests on welds in metallic materials — Fracture test. ISO 9017:2017 specifies test‑specimen sizes and procedures for carrying out fracture tests to obtain information about the types, sizes and distribution of internal imperfections (porosities, cracks, lack of fusion, lack of penetration, solid inclusions) observed on fracture surfaces of welded joints in metallic materials.

Abstract

ISO 9017:2017 defines how to prepare and fracture weld test specimens (by bending or tension, static or dynamic loading), including notation for specimen denomination, examination length/thickness and examination area, and the method for examining fracture surfaces to characterise internal weld imperfections. The standard applies to fusion‑welded joints in metallic products of thickness greater than or equal to 2 mm.

Scope

Specifies sizes of test specimens and procedures for fracture tests on welded joints to reveal and characterise internal imperfections on fracture surfaces. Applies to metallic materials in all product forms where the joint is made by any fusion welding process and the weld thickness is ≥ 2 mm. Tests are normally carried out at ambient temperature unless otherwise specified; fracturing can be induced by bending or tension, and notch geometry, method and test temperature may be varied as required.

Key topics and requirements

• Specification of test‑specimen denominations and reporting format (examination length, examination thickness, examination area) for different weld types (fillet, butt, etc.).
• Procedures to induce fracture (bending or tensile loading; static or dynamic) and guidance on notch types and locations to ensure fracture through the weld metal or desired region.
• Instructions for preparing, notching and aligning specimens so the fracture surface can be examined for internal discontinuities (porosity, cracks, lack of fusion/penetration, inclusions).
• Definition of how to measure and report the size and distribution of imperfections on the fracture surface (examination length/thickness and total examination area).
• Reference to ambient test condition by default and provision for varying temperature or notch geometry where required by the application or specification.

Typical use and users

Used by welding engineers, metallurgists, welding inspectors, quality managers, testing laboratories and certification bodies for: weld procedure qualification, failure investigations, production quality checks where destructive examination is required, and research/ development of welding consumables and processes. Common application areas include fabrication, pressure‑vessels, pipelines, shipbuilding, petrochemical, heavy engineering and structural steelworks.

Related standards

Standards commonly used together with ISO 9017 include: ISO 9016 (impact tests — specimen location and notch orientation), ISO 4136 (transverse tensile test), ISO 5817 (quality levels for imperfections in fusion‑welded joints), ISO 17637 (visual testing of welds) and ISO 15614 (welding procedure specification and qualification). These documents cover complementary destructive and non‑destructive examination methods, acceptance levels and welding procedure qualification practices.

FAQ

Q: What is this standard?

A: ISO 9017:2017 is an ISO International Standard that specifies specimen sizes and procedures for fracture tests on welded joints to characterise internal imperfections visible on fracture surfaces.

Q: What does it cover?

A: It covers how to prepare and fracture specimens (by bending or tension, static or dynamic) so the fracture surface can be examined for porosity, cracks, lack of fusion, lack of penetration and inclusions; it defines specimen denomination, examination length/thickness/area and reporting. Applies to fusion‑welded metallic joints with thickness ≥ 2 mm.

Q: Who typically uses it?

A: Welding engineers, materials/test laboratories, welding inspectors, quality/certification bodies and designers who need destructive fracture examination as part of welding procedure qualification, production inspection or failure analysis.

Q: Is it current or superseded?

A: Edition 2 (2017) is published and was reviewed and confirmed as current during ISO’s 2022–2023 systematic review (review closed and confirmation recorded in March 2023). It supersedes ISO 9017:2001. Users should check the issuing body for any amendments or later revisions when planning compliance.

Q: Is it part of a series?

A: Yes — ISO 9017 is part of ISO’s family of “Destructive tests on welds in metallic materials” (other related parts cover impact tests, tensile tests and specimen location/orientation) and is intended to be used alongside related parts (e.g., ISO 9016, ISO 4136) and application/acceptance documents such as ISO 5817 and ISO 15614.

Q: What are the key keywords?

A: Fracture test; weld fracture; destructive test; specimen size; weld discontinuities; porosity; lack of fusion; lack of penetration; welding inspection; metallic materials.
