Full title and description

Destructive tests on welds in metallic materials — Impact tests — Test specimen location, notch orientation and examination. ISO 9016:2022 specifies how to describe and report the location of test specimens taken from welded butt joints, the orientation and designation of notches, and the additional reporting requirements needed when performing impact (Charpy-type) tests on welded joints.

Abstract

This International Standard specifies the method to be used when describing test specimen location and notch orientation for the testing and reporting of impact tests on welded butt joints. It applies to impact tests on metallic materials in all product forms made by any fusion or pressure welding process. ISO 9016:2022 is intended to be used in addition to the ISO 148 series (Charpy impact tests) and provides specimen denomination and extra reporting requirements specific to welded joints.

Scope

ISO 9016:2022 covers the description, denomination and reporting of test specimen location and notch orientation for impact tests performed on welded butt joints. The standard applies to impact testing of metallic materials in any product form and for joints produced by fusion or pressure welding processes. It supplements the procedures and requirements given in the ISO 148 series by specifying how to identify specimen positions relative to the weld, orientation of the notch with respect to weld geometry, and additional information to include in test reports.

Key topics and requirements

• Specification of standard terms and specimen denominations for welded-joint impact testing (e.g., weld centre, heat-affected zone, parent material).
• Rules for selecting and describing specimen location relative to the weld and joint geometry.
• Required notch orientation and notch positioning conventions for Charpy-type impact specimens taken from welds.
• Minimum reporting requirements specific to welded specimens (location, orientation, weld process/type, specimen designation).
• Use as a supplement to ISO 148 (Charpy impact test series) rather than a replacement of test method details.
• Applicability to specimens taken from products made by fusion and pressure welding processes.

Typical use and users

ISO 9016:2022 is used by welding engineers, metallurgical laboratories, quality assurance and inspection personnel, certification bodies, and standards committees. Typical users include materials testing laboratories performing Charpy impact tests on welded joints, welding procedure qualification teams, manufacturers and fabricators verifying welded-joint toughness, and third-party inspection/acceptance authorities.

Related standards

Key related standards include the ISO 148 series (Charpy impact test methods and requirements) which defines the basic test method; other weld testing standards such as ISO 4136 (transverse tensile test) and various ISO/EN standards on destructive tests of welds and welding procedure qualification. National and regional identical/adopted versions exist (for example EN ISO 9016:2022).

FAQ

Q: What is this standard?

A: ISO 9016:2022 is an International Standard that defines how to designate, locate and report specimens and notch orientation when performing impact (Charpy-type) tests on welded butt joints.

Q: What does it cover?

A: It covers specimen location descriptions, notch orientation conventions, specimen denomination, and additional reporting requirements specific to impact testing of welded joints. It is intended to be used alongside the ISO 148 series that defines the Charpy test method itself.

Q: Who typically uses it?

A: Welding engineers, materials testing laboratories, QA/QC inspectors, welding procedure qualification personnel, manufacturers and fabricators, and conformity assessment bodies involved in welded-joint toughness evaluation.

Q: Is it current or superseded?

A: ISO 9016:2022 is the current edition published 31 March 2022. It supersedes ISO 9016:2012 (the previous edition).

Q: Is it part of a series?

A: Yes. It is part of the family of standards on destructive tests of welds in metallic materials and is intended to be used in conjunction with the ISO 148 series (Charpy impact tests) and other weld testing standards.
