ISO 17635:2016 Non-destructive testing of welds

What is ISO 17635:2016 Non-destructive testing of welds — General rules for metallic materials?

ISO 17635:2016 Non-destructive testing of welds outlines the general rules and guidelines for the non-destructive testing (NDT) of welds in metallic materials. Non-destructive testing is a critical component of quality assurance processes in various industries, from construction to manufacturing and energy production. It serves as a comprehensive reference for NDT techniques to evaluate the integrity, safety, and quality of welded joints without damaging the component or structure being tested.

The standard serves several key objectives:

Harmonization: It aims to harmonize different methods and terminologies used in non-destructive testing across various industries and countries.
Quality Assurance: By prescribing guidelines, the standard helps in ensuring the quality and reliability of welded components. This is crucial for safety, particularly in high-stakes industries like aviation, construction, and energy.
Procedure & Documentation: It provides a framework for planning, executing, and documenting NDT procedures. This helps organizations maintain a high standard of quality and compliance with regulatory requirements.
Interchangeability: The standard provides a common language that allows for ease of communication and data interchange between stakeholders—ranging from inspectors and quality control personnel to suppliers and regulatory agencies.
Technical Specification: It outlines various techniques for non-destructive testing, such as radiographic, ultrasonic, magnetic particle, dye penetrant, and eddy current testing, among others.
Qualification and Training: The standard also outlines the competence requirements for personnel responsible for conducting the NDT.
Review & Evaluation: It provides guidelines for the assessment and evaluation of test results, including criteria for acceptance or rejection based on predetermined standards.

Overall, ISO 17635:2016 serves as an overarching document that may be supplemented by other, more specific standards related to non-destructive testing for particular types of materials or applications. By adhering to the guidelines set forth in ISO 17635:2016, organizations can improve the reliability and durability of their products, enhance operational efficiency, and mitigate the risks associated with faulty welds. Compliance with this standard is often a regulatory requirement and can serve as a benchmark for quality in contractual agreements.

Also, for organizations interested in obtaining certifications that validate their compliance with quality management systems or specific industry standards, understanding and implementing the recommendations of ISO 17635:2016 can be an integral part of that process.
