EN 14865-2:2006/FprA2

Railway applications - Axlebox lubricating greases - Part 2: Method to test the mechanical stability to cover vehicle speeds up to 200 km/h

This European Standard specifies a test method and sets the acceptance criteria for the determination of the mechanical stability of lubricating greases intended for the lubrication of axlebox bearings according to EN 12081. In the test, impacts are applied to the lubricating grease so that only very stable lubricating greases will perform acceptably. The method is used in a discrimination process for finding lubricating greases of such mechanical stability that they are considered accepted lubricating greases for more extensive performance tests according to EN 12082.
For purposes of quality assurance and quality control, this test method is also used for batch testing of lubricating greases.

Overview

EN 14865-2:2006/FprA2 is a European standard developed by CEN focusing on railway applications, specifically concerning axlebox lubricating greases. This standard outlines a test method designed to determine the mechanical stability of lubricating greases used in axlebox bearings of railway vehicles operating at speeds up to 200 km/h. The mechanical stability test is crucial for ensuring that lubricating greases maintain their functional properties under the stresses and impacts experienced during high-speed rail operations.

The test not only establishes acceptance criteria but also serves as a key step in the quality assurance and quality control processes, including batch testing of lubricants. The methodology supports the identification of lubricating greases stable enough to proceed to more comprehensive performance evaluations as per EN 12082.

Key Topics

• Mechanical Stability Testing
  EN 14865-2:2006/FprA2 specifies a rigorous method for evaluating the mechanical stability of axlebox lubricating greases by subjecting them to impacts simulating operational stresses at speeds up to 200 km/h. Only greases exhibiting high stability pass the test.

• Acceptance Criteria
  The standard defines benchmarks that lubricating greases must meet to be considered mechanically stable, ensuring reliable performance of axlebox bearings.

• Relationship to Other Standards
  This testing method complements EN 12081, which covers the lubrication of axlebox bearings, and is used to select greases for more extensive testing under EN 12082.

• Quality Assurance and Batch Testing
  EN 14865-2 also supports ongoing quality control efforts by providing a reproducible test method for batch testing of lubricating greases, ensuring consistency and reliability in production.

• Compliance with EU Directives
  The standard has been prepared under the mandate of the European Commission to fulfill essential requirements of EU Directive 2008/57/EC related to railway interoperability, supporting safety and technical compatibility requirements.

Applications

• Railway Axlebox Bearing Lubrication
  The primary application of this standard is in the testing and qualification of lubricants used in axlebox bearings of railway vehicles operating up to 200 km/h. It helps guarantee the durability and performance of lubricants under mechanical stress.

• Manufacturing and Quality Control
  Lubricant manufacturers utilize this standard to test batches and ensure compliance with mechanical stability requirements, maintaining consistent lubricant quality for railway clients.

• Railway Vehicle Maintenance
  Railway operators and maintenance organizations can apply EN 14865-2 to verify that greases used in service meet necessary stability criteria, thus preventing bearing failures caused by grease degradation.

• Product Development
  Research and development teams in lubricant production use this standard to assess new grease formulations targeted at high-speed rail applications.

Related Standards

• EN 12081 – Specifies lubricants for axlebox bearings, forming the basis for the test method in EN 14865-2.
• EN 12082 – Defines detailed performance tests for lubricating greases after stability has been established by EN 14865-2.
• EU Directive 2008/57/EC – Addresses interoperability requirements for railway systems, with EN 14865-2 supporting compliance for axlebox bearing lubricants.
