Staying current with the ensures you are not designing for yesterday's standard.
ISO 5948, titled "Railway rolling stock material — Axles — Quality requirements," establishes the strict quality standards required for manufacturing and delivering steel axles used in railway rolling stock.
Lists sister standards (like ISO 6892 for tensile testing) required to implement ISO 5948.
Ultrasonic testing (UT) is a non-destructive testing (NDT) method that introduces high-frequency sound waves into the material. The waves travel through the steel and reflect back when they hit a boundary or an internal flaw. Under ISO 5948, UT aims to achieve the following:
Manufacturers adhering to ISO 5948 must satisfy strict metallurgical and physical criteria. The standard acts as a quality assurance framework between the steel manufacturer, the axle forge, and the railway operator. A. Chemical Composition
Test pieces are cut from designated areas of the axle to evaluate:
