It provides a standardized framework to ensure that critical railway components, specifically wheels, axles, and tyres, are free from internal defects that could compromise safety. Core Purpose and Scope
The standard has undergone several revisions to keep pace with evolving rail technologies and safety demands: ISO 5948:2018 - Ultrasonic acceptance testing
The standard defines the conditions and acceptance criteria for non-destructive ultrasonic testing (NDT). It is typically invoked when product-specific standards (such as , ISO 1005-3 , or ISO 1005-6 ) require mandatory ultrasonic testing or when such tests are agreed upon during the ordering process. Key components covered include: Solid Wheels: For both tractive and trailing stock. Axles: Both solid and hollow variants. Tyres: Rough-rolled tyres for various railway applications.
