Railway Applications - Axlebox lubricating greases - Part 1: Method to test the ability to lubricate

This European Standard specifies a testing method and sets the acceptance criteria for the determining of the lubrication ability of lubricating greases intended for the lubrication of axlebox bearings. The lubricating ability, primarily related to the capability of lubricating greases to protect against wear, is determined in a roller bearing lubricant test rig. Wear of the rolling bearing rollers, the frictional behaviour and temperature during the test are used to discriminate between lubricating greases.
NOTE 1   The testing method is referred to in EN 12081.
The method described is carried out in order to test axlebox greases for ordinary-speed vehicles, with speeds up to 200 km/h, and for greases intended for high-speed vehicles, with speeds up to 300 km/h. The method is a discriminating process, and those greases that pass will be subject to more extensive performance tests.
NOTE 2   In EN 12082 a more extensive rig performance test is described in detail. This rig performance test will check the satisfactory function of the assembly of box housing, bearing, sealing and grease during a simulated journey.
For purpose of quality assurance and quality control, this test method is also used for batch testing of greases intended for use in axleboxes.
For light rail and tramway applications other standards or documents agreed between the customer and the supplier may be applied.

Overview

EN 14865-1:2009/FprA1 is a CEN standard that specifies a laboratory method to determine the lubrication ability of axlebox lubricating greases used in railway axlebox bearings. The method uses a roller bearing lubricant test rig to discriminate between products by measuring wear, frictional behaviour and temperature during a controlled test. Greases that pass this discriminating test are eligible for more extensive performance evaluations.

This amendment supports conformity with EU Directive 2008/57/EC as referenced in Annex ZA and is intended for ordinary-speed vehicles (up to 200 km/h) and high-speed vehicles (up to 300 km/h). It is also applied for routine quality assurance and batch testing of axlebox greases.

Key Topics

• Scope and purpose: Defines the test method and acceptance criteria for lubrication ability of greases intended for axlebox bearings.
• Test rig and measurements: Uses a roller bearing test rig; discrimination is based on wear of rolling bearing rollers, frictional behaviour and temperature rise.
• Operational ranges: Method applies to greases for ordinary-speed and high-speed vehicles (speeds up to 200 km/h and up to 300 km/h respectively).
• Discriminating process: Intended to filter candidate greases; passing greases proceed to more extensive rig performance tests.
• Quality assurance: Method suitable for batch testing and factory quality control to maintain consistent grease performance.

Applications

This standard is directly relevant to stakeholders involved in railway maintenance, procurement and testing:

• Rolling stock manufacturers and OEMs evaluating lubricant compatibility with axlebox bearings
• Railway operators and maintenance teams performing batch quality control on supplied greases
• Lubricant producers validating grease formulations for railway axlebox applications
• Test laboratories performing standardized lubrication ability assessments

Practical benefits include:

• Clear acceptance criteria to reduce bearing wear risk
• A repeatable test for batch QA/QC to ensure consistent field performance
• Early discrimination of greases prior to costly full assembly or rig performance testing

Related Standards

• EN 12081: referenced in EN 14865-1 for related test method references
• EN 12082: describes a more extensive rig performance test that evaluates the assembly of box housing, bearing, sealing and grease during a simulated journey
• Annex ZA in EN 14865-1 links the standard to essential requirements of EU Directive 2008/57/EC

Notes

• The method is a preliminary, discriminating test; passing greases should undergo full performance testing where required.
• For light rail and tramway applications, parties may apply alternative standards or mutually agreed documents.
