Introduction

Interpretation of the core content of the standard

Technical dimension	Freight car/passenger car	Locomotive	EMU
Measurement period	≤3min/≤6min	≤15min	≤15min(trailer)/≤10min(EMU)
Wheel diameter error	±0.3mm
Wheel rim thickness error	-0.2~0mm

Key Technical Requirements

The standard stipulates that the wheel set measuring machine must be equipped with a simulated standard wheelset that can be traced back to the national benchmark. The allowable deviations of its key parameters are:

Flange height: ±0.03mm
Wheel set inner distance: ±0.1mm
Brake disc center distance: ±0.15mm

Implementation Recommendations

Equipment Selection Guide

According to Article 4.2 of TB/T 3476-2017, the measuring machine model should follow the CLD-XXX-Enterprise Logo coding rules:

The initials H/K/J/D correspond to freight cars/passenger cars/locomotives/EMUs respectively
It is recommended to select extended models with serial numbers above 300
Give priority to equipment with remote fault diagnosis function

Maintenance points

Article 5.12 of the standard emphasizes: The calibration results are valid for a long time and recalibration is only required in the following cases:
