For a welding coordinator on a green-steel mega-project, this means one clear reference to navigate the entire quality system. Instead of cross-referencing multiple documents, the new grouping reduces ambiguity in selecting the right NDT method and acceptance level for each weld class.
A practical example: For an EXC3 structural joint under EN 1090-2, ISO 17635 now explicitly maps ISO 5817 level B (stringent) to UT per ISO 17640. No more guesswork.
The 2024 update also aligns with the latest editions of ISO 3834 and ISO 14731, ensuring consistency across design, fabrication, and inspection.
How does your organization handle the transition when a grouping standard like ISO 17635 is revised?
