: Specifically applies to solid wheels, rough-rolled tyres, and both solid and hollow axles used in tractive and trailing rail stock. Key Technical Requirements of ISO 5948:2018
Many engineering universities and large railway companies have an institutional subscription to ISO standards. If you are a student or employee, check your internal intranet for a free, legal PDF download.
Mandates how tracing data (heat number, manufacturer logo, date) must be stamped onto the axle end. How to Legally Sourced an ISO 5948 PDF iso 5948 pdf
Ultrasonic testing (UT) is a method that uses high-frequency sound waves. A probe sends a pulse of sound into the material. When the sound wave encounters a boundary, like a defect or the far side of the part, it reflects back. By analyzing the time it takes for the echo to return and the strength of the signal, a trained technician can determine the location and size of internal defects without damaging the part.

The ISO 5948 PDF document typically includes the following content:
The primary focus of the standard is to ensure that components subjected to immense dynamic loads, like railway axles and wheelsets, are completely free of structural flaws that could lead to catastrophic failure. Scope and Core Applications Mandates how tracing data (heat number, manufacturer logo,
Scanning is conducted across the tread surface and the rim faces to detect defects oriented parallel or perpendicular to the rolling direction. 5. Acceptance Levels
ISO 5948 defines specific acceptance classes based on the severity and location of the recorded indications. Discontinuities exceeding the reference threshold are evaluated, and components are either accepted, reworked, or rejected based on these strict limits.
