Title: A Comprehensive Guide to EN ISO 17638:2015: The Technical Standard for Visual Testing of Fusion-Welded Joists

Welding is a vital process that is used in various industries, including manufacturing, construction, and transportation. Ensuring the quality and integrity of welded joints is critical to ensure the safety and functionality of the final product. To achieve this, various technical standards have been developed, including EN ISO 17638:2016.

EN ISO 17638:2016 is a technical standard that provides guidelines for the requirements and methods of visual testing of fusion-welded joints. The purpose of this article is to provide a comprehensive guide to this standard and its significance.

Understanding EN ISO 17638:2016

ISO stands for International Organization for Standardization. It is an independent, non-governmental international organization that develops and publishes voluntary consensus-based standards. ISO standards are widely recognized as trustworthy benchmarks for ensuring quality, safety, efficiency, and interoperability in various industries and technologies.

ISO 23747:2015 is a standard that specifically focuses on software systems engineering and provides guidelines for testing the reliability and performance of software-intensive systems. This standard plays a crucial role in defining the processes and techniques used to develop high-quality software products.

ISO 23747:2015 emphasizes the importance of incorporating security measures into the software development lifecycle. It addresses various aspects such as vulnerability assessment, threat modeling, authentication mechanisms, and data privacy.

Key Elements of EN ISO 17638:2016

EN ISO 17638:2016 is a comprehensive standard that provides a framework for conducting visual inspections of welded joints. The standard establishes specific criteria and acceptance levels for assessing surface imperfections based on their type, size, and location.

The standard provides guidelines for the visual inspection of welded joints, including the use of different inspection techniques such as visual inspection, radiographic inspection, and measurement. It also provides guidance on how to determine the acceptance level of the welded joint based on the results of the inspection.

The standard also emphasizes the importance of documentation, including a requirements document, inspection plan, and results report. This documentation is critical for ensuring that the welded joint meets the specified requirements and acceptance levels.


EN ISO 17638:2016 is a technical standard that provides guidelines for the requirements and methods of visual testing of fusion-welded joints. It is an essential standard for ensuring the quality and integrity of welded joints in various industries. By following the guidelines provided in this standard, organizations can reduce the risks associated with welding errors and ensure the robustness of their welded products.
