EN 12082:2007/FprA1

Railway applications - Axleboxes - Performance testing

This European Standard specifies the quality requirements of greases intended for the lubrication of axlebox rolling bearings according to EN 12080, required for reliable operation of trains on European networks. It covers the approval procedure, the method of quality control and quality monitoring of the grease. The grease requirements are given for two speed classes.

Overview

EN 12082:2007/FprA1 is a European Standard developed by CEN, focusing on railway applications-specifically axleboxes and their performance testing. This standard specifies the quality requirements for greases used in lubricating axlebox rolling bearings according to EN 12080. Ensuring the correct lubrication is critical for the reliable operation of trains across European rail networks. The standard defines an approval procedure, quality control methods, and continuous quality monitoring of the grease, distinguishing requirements for two different speed classes.

This amendment supports compliance with EU Directive 2008/57/EC concerning the interoperability of the trans-European rail system. As such, EN 12082:2007/FprA1 plays an essential role in guaranteeing safety, reliability, and interoperability in railway rolling stock maintenance and performance.

Key Topics

• Axlebox Rolling Bearings Lubrication
  This standard outlines the specifications for greases applied to axlebox bearings, which are critical components bearing the wheelsets of trains.

• Quality Assurance and Monitoring
  EN 12082:2007/FprA1 establishes procedures for grease approval, along with ongoing quality control and monitoring to ensure consistent performance over time.

• Speed Classifications
  The grease requirements differ according to speed categories, enabling appropriate lubrication solutions for various operational conditions on European rail networks.

• Compliance with EU Directive 2008/57/EC
  The standard aligns with this directive, which mandates interoperability and safety standards across member states, supporting seamless cross-border rail operations.

• Performance Testing Protocols
  Detailed testing methods for the performance of axleboxes ensure durability and reliability under different operating scenarios.

Applications

EN 12082:2007/FprA1 is primarily applied in the railway engineering sector to:

• Ensure high-performance lubrication of axlebox rolling bearings, reducing wear and extending component life.
• Facilitate safe and reliable train operations by maintaining proper bearing functionality.
• Support cross-European interoperability by conforming to harmonized technical requirements.
• Aid manufacturers and maintenance organizations in developing and validating lubrication products that meet strict railway standards.
• Enhance quality control systems for grease production and application in railway maintenance workflows, leading to improved operational efficiency.
• Serve as a reference for railway regulatory bodies and certification entities overseeing compliance with essential safety requirements.

Related Standards

• EN 12080 – Railway applications: Specifies the technical details for axlebox rolling bearings which EN 12082 complements by focusing on grease quality and testing.
• EU Directive 2008/57/EC – Interoperability of the trans-European rail system: EN 12082:2007/FprA1 supports adherence to the essential requirements of this directive.
• EN 12082:1998 – Previous version addressing axlebox health monitoring and hot axle box detection, relevant to safety and maintenance standards.
• Other CEN Technical Committees Guidelines for railway vehicle components and subsystems ensure integrated compliance across rolling stock.

---

By adhering to EN 12082:2007/FprA1, railway operators and product developers can ensure the performance and safety of axlebox lubrication systems, directly contributing to operational reliability and extended axlebox service life. This standard is a key part of the suite of regulations driving interoperability and quality assurance in Europe’s rail transport industry.
