T/CSTM 00687-2023 Non-Destructive Testing of Rail Transportation Materials: Electromagnetic Ultrasonic Detection Method for Residual Stress in Locomotive and Carriage Wheels

Scope

Scope: This document specifies the terms and definitions, method overview, inspection personnel, inspection equipment, calibration of acoustic elasticity coefficients, inspection steps, acceptance, and inspection records for the electromagnetic ultrasonic detection of residual stress in new-made complete wheels (referred to as wheels) used in railway locomotives and rolling stock. This document is applicable to the detection of circumferential residual compressive stress distribution within the wheel rim below the wheel tread. The methods specified in this document cannot replace the measurement of residual stress distribution in the wheel rim using the cutting and release method, unless it can be proven that the results obtained by applying this method are identical to the distribution values obtained by the cutting and release method.
