Full title and description

STB DIN EN ISO 14329: Resistance welding — Destructive tests of welds — Failure types and geometric measurements for resistance spot, seam and projection welds. German version: "Widerstandsschweißen — Zerstörende Prüfung von Schweißverbindungen — Brucharten und geometrische Messgrößen für Widerstandspunkt-, Rollennaht- und Buckelschweißungen".

Abstract

ISO 14329:2003 defines the fracture (failure) types and the geometric measurement conventions to be used when carrying out destructive tests on resistance spot, seam and projection welds. The definitions give a common basis for reporting test results and for related standards and test methods addressing weld integrity and performance under different loading configurations.

Scope

This standard establishes terminology, classification of fracture types and standard geometric measurement definitions for destructive testing of resistance spot, seam and projection welds. It applies where different loading configurations produce different stress distributions in the weld and where consistent, comparable measurement and reporting of weld failure geometry and types are required. The intention is to provide a common reference usable by test laboratories and other weld-related standards.

Key topics and requirements

• Definitions and classification of weld failure (fracture) types observed in destructive tests (e.g., nugget pull-out, interfacial fracture, base-metal fracture, mixed modes).
• Standard geometric measurement conventions for features of weld failures (e.g., nugget diameter, projected area, edge distances) to ensure repeatable reporting.
• Guidance on measurement locations and orientations for spot, seam and projection weld samples subjected to different loading configurations.
• Requirements for clear reporting so results are comparable between laboratories and referenced by related welding test standards.
• Role as a base/reference document for other destructive test methods and for harmonizing terminology across national/adopted versions.

Typical use and users

Used by welding engineers, quality and inspection personnel, metallurgical and materials laboratories, third-party test houses, automotive and aerospace manufacturers, research institutes and standards committees. Typical activities include destructive weld testing for quality control, failure analysis, process qualification and inter-laboratory comparison.

Related standards

ISO 14329 is referenced alongside and complements other resistance-welding and weld-testing standards such as ISO 14327 (testing procedures for resistance welding), ISO 17653 (torsion test of spot welds), ISO 17654 (pressure test of seam welds) and standards covering weld acceptance criteria (for example ISO/EN documents on weld quality). National/adopted EN and DIN versions carry identical content when adopted.

FAQ

Q: What is this standard?

A: ISO 14329:2003 (adopted as EN ISO and national versions such as DIN EN ISO 14329) is a descriptive standard that defines failure types and the geometric measurement conventions used when performing destructive tests on resistance spot, seam and projection welds.

Q: What does it cover?

A: It covers terminology for fracture types and prescribes how to measure and report geometric features of failed welds so that results are consistent and comparable across tests and laboratories. It is a reference for other, more specific destructive test methods.

Q: Who typically uses it?

A: Welding engineers, laboratory technicians, QA/QC inspectors, manufacturers (automotive, transport, heavy industry), accreditation bodies and standards developers use it to interpret and report destructive weld test results.

Q: Is it current or superseded?

A: ISO 14329:2003 has been withdrawn from the ISO catalogue (the edition is no longer active). There have been proposals and project work on related items, but a direct replacement project was at one point proposed and later abandoned; users should consult current ISO and national standards catalogues for the latest applicable weld-testing standards and any newer documents that cover the same topics.

Q: Is it part of a series?

A: It sits among a set of resistance-welding and weld-testing standards (ISO and EN family) that together define procedures, test methods and acceptance criteria—for example standards dealing with weldability lobes, seam-weld pressure tests and torsion tests of spot welds. It is intended as a cross-reference/base document rather than a standalone method series.

Q: What are the key keywords?

A: Resistance welding, destructive testing, fracture types, geometric measurements, spot weld, seam weld, projection weld, nugget, weld inspection, ISO 14329.
