What is ISO 16809:2016 ?

Title: A Comprehensive Guide to ISO 16809:2016 and EN ISO 17638:2016

Introduction:

Surface texture parameters are a critical factor in ensuring accurate measurements and reliable data analysis.ISO 16809:2016 is a technical standard that specifies multiple attributes of surface texture parameters. It provides guidelines for evaluating the characteristics of surfaces, such as roughness, waviness, and lay. By defining standardized measurement procedures and terminology, this standard ensures consistency and comparability in the assessment of various surfaces.

EN ISO 17638:2016 is a complementary standard that provides a comprehensive framework for conducting visual inspections of welded joints. It aims to detect surface imperfections that may compromise the strength and functionality of the welds. This standard establishes specific criteria and acceptance levels for assessing these imperfections based on their type, size, and location.

This article will explore the importance of ISO 16809:2016 and EN ISO 17638:2016 in ensuring the quality and integrity of welded joints. It will discuss the key elements of EN ISO 17638:2016 and how it can be used to improve the visual inspection of welded joints.

Principles of ISO 16809-2016:

ISO 16809:2016 is a technical standard that provides guidelines for the requirements and methods of visual testing of fusion-welded joints. It specifies multiple attributes of surface texture parameters, such as roughness, waviness, and lay.

ISO 16809:2016 aims to provide a standardized method for evaluating the surface texture of welded joints, which can be used for ensuring the quality and integrity of welds. It defines specific criteria and acceptance levels for assessing the roughness, waviness, and lay of surfaces.

The standard also provides guidance on the selection of the appropriate test method and equipment for different types of welded joints. It explains how to use visual inspection techniques, such as light and shadow observation, to evaluate the surface texture of welded joints.

Principles of EN ISO 17638:2016:

EN ISO 17638:2016 is a complementary standard that provides a comprehensive framework for conducting visual inspections of welded joints. It aims to detect surface imperfections that may compromise the strength and functionality of the welds.

The standard defines specific criteria and acceptance levels for assessing the surface imperfections of welded joints based on their type, size, and location. It provides guidance on the use of visual inspection techniques, such as light and shadow observation, to identify these imperfections.

The standard also explains how to document the results of the visual inspections and how to report any non-conformities. It provides guidance on the training and certification of visual inspectors and how to establish a visual inspection program.

Conclusion:

ISO 16809:2016 and EN ISO 17638:2016 are two important standards that play a crucial role in ensuring the quality and integrity of welded joints. They provide guidelines for evaluating the surface texture parameters of welded joints and document the results of visual inspections.

By using these standards, manufacturers, engineers, and inspectors can ensure that welded joints meet the required specifications and are free from defects that may compromise their strength and functionality.

Furthermore, these standards can be used to improve the visual inspection of welded joints, which can help detect surface imperfections early and ensure the quality of welded joints.

EN ISO 17638:2016 is a valuable tool for ensuring the quality of welded joints and can be used in conjunction with ISO 16809:2016 to provide a comprehensive framework for evaluating the surface texture of welded joints.

In conclusion, ISO 16809:2016 and EN ISO 17638:2016 are important standards that should be implemented in all welding processes to ensure the quality and integrity of welded joints.
