The SN EN ISO 17637:2017 standard outlines the guidelines for non-destructive visual testing of fusion-welded joints in metallic materials, published by CEN and ISO. It serves as a critical reference for professionals involved in welding inspection and quality assurance.

Purpose and objectives

The purpose of the SN EN ISO 17637:2017 standard is to establish a comprehensive framework for the visual inspection of fusion-welded joints in metallic materials. This standard aims to ensure that welds meet specified quality requirements through effective non-destructive testing methods. By providing clear guidelines on inspection procedures, personnel qualifications, and reporting results, it promotes consistent practices across industries, thereby enhancing the reliability and safety of welded structures.

Scope: who must comply

The SN EN ISO 17637:2017 standard applies to professionals and organizations involved in the fabrication and inspection of welded metallic structures. Typical industries include manufacturing, construction, and energy, where fusion-welded joints are prevalent. Companies seeking to comply with this standard often include manufacturers of heavy machinery, automotive parts, and pressure vessels, as well as construction firms responsible for structural integrity in building projects. Adhering to this standard is crucial for achieving certification and ensuring quality assurance in welding practices.

How SN EN ISO 17637:2017 relates to other standards

The SN EN ISO 17637:2017 standard complements several related standards, including:

• ISO 17635: This standard provides guidelines for the non-destructive testing of welds, focusing on a broader range of techniques.
• ISO 9001: A general quality management standard that can be applied alongside SN EN ISO 17637:2017 for comprehensive quality assurance.
• ISO 3834: This standard outlines quality requirements for fusion welding, further supporting welding quality management systems.

Revision history and current status

The SN EN ISO 17637:2017 was published by the European Committee for Standardization (CEN) and is the latest revision following the previous ISO 17637:2016 standard. The most recent changes include updated definitions, improved clarity in testing procedures, and enhanced guidelines for personnel qualifications to align with evolving industry practices.
