Overview
EN ISO 8494:2013 – Metallic materials – Tube – Flanging test is a European and International Standard developed by CEN and ISO for assessing the ability of metallic tubes with circular cross-sections to undergo plastic deformation during flange formation. This standard specifies a widely recognized and reproducible procedure for the flanging test, making it a key reference for manufacturers, quality control labs, and mechanical designers working with metallic tubes. The test method is mainly applicable to metallic tubes with an outside diameter up to 150 mm and a wall thickness no greater than 10 mm, though product standards may further clarify the applicable dimensions.

Key Topics
Applications
The EN ISO 8494:2013 flanging test is an essential procedure in:
- Tube Manufacturing: Ensuring tubes can withstand flanging operations without failure, critical for products requiring end forming in fields like automotive, aerospace, HVAC, and construction.
- Product Development: Supporting materials selection and engineering design by quantifying ductility and workability of tube materials.
- Quality Control and Inspection: Detecting batch or process variations that impact forming performance, helping minimize in-service failures.
- Supplier Compliance: Demonstrating conformity with contractual and regulatory specifications for metallic tubes, especially where specific forming capabilities are required.
Tubes passing the flanging test are more likely to perform reliably during downstream forming, assembly, or installation, bolstering confidence in structural integrity and component lifespan.
Related Standards
Organizations involved with metallic tubes and mechanical testing often reference EN ISO 8494 alongside:
- ISO 8492 – Bending test for metallic tubes
- ISO 8493 – Drift expanding test for metallic tubes
- EN ISO 6892 – Tensile testing of metallic materials
- ISO 7438 – Bend test for metallic materials
Using this family of standards ensures a comprehensive approach to mechanical testing, supporting consistent material performance, quality assurance, and international market access.
EN ISO 8494:2013 standardizes the flanging test for metallic tubes, enabling manufacturers, laboratories, and purchasers to assess tube formability efficiently and consistently, ensuring product quality and regulatory compliance in demanding industrial applications.
