UIC Leaflet 532: Standards for Railway Wheelsets and Axles

Introduction to UIC Leaflet 532

UIC Leaflet No: 532 is an international standard from the International Union of Railways (UIC) that specifies requirements for railway wheelsets and axles. It ensures safety, reliability, and durability of rolling stock components in various operational conditions.

Scope and Purpose

The leaflet covers design, material selection, testing, maintenance, and inspection of wheelsets and axles. Its purpose is to standardize performance criteria, reduce the risk of failures, and guarantee safe train operations.

Key Components

• Wheelset Design: Axle dimensions, wheel profile, and tolerances for rolling stability.
• Material Requirements: High-strength steel specifications for durability and fatigue resistance.
• Testing and Inspection: Dynamic and static load tests, ultrasonic inspections, and periodic maintenance checks.
• Operational Performance: Guidelines for maximum speed, axle load, and compatibility with different track gauges.
