A: The scope explicitly says passenger coaches. For freight wagons, refer to EN 15153-1 (for warning lights) or AAR S-401 (for North America).
Not all labs can certify to ISO 5948. Look for laboratories accredited by: iso 5948 pdf
Send them the relevant pages from the ISO 5948 PDF – especially Annex A (informative) which provides a test report template.
A: Yes, as of 2025, ISO 5948:1994 remains a current standard. However, check www.iso.org for any announcements of a revision. Many experts expect an update around 2026-2027 to include LED-specific requirements. Copy the table from Clause 5 (“Test methods
ISO 5948 was designed to ensure the safety and reliability of critical steel components used in the railway industry. It covered the acceptance criteria for magnetic particle testing—a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities (cracks, inclusions, seams) in ferromagnetic materials.
The standard was applicable to:
The standard categorized indications found during testing based on their appearance and size.
After certification, store the PDF along with your test reports for at least 15 years (typical product liability period for railway components). Send them the relevant pages from the ISO
