Overview
EN 12081:2007/FprA1 is a CEN European Standard for railway axlebox lubricating greases. It specifies the quality requirements for greases used to lubricate axlebox rolling bearings (per EN 12080) to ensure reliable train operation across European networks. The amendment FprA1 updates the foreword and Annex ZA to reference EU Directive 2008/57/EC, clarifying the standard’s role in conformity assessment and interoperability.
Key topics and requirements
- Quality requirements for greases intended specifically for axlebox rolling bearings (compatibility with EN 12080 referenced).
- Approval procedure: criteria and administrative process for approving axlebox greases for railway use.
- Quality control and monitoring: methods and obligations for ongoing quality assurance and verification during production and in-service.
- Two speed classes: grease performance requirements are defined for two different speed classifications of rolling bearings.
- Conformity and regulatory linkage: Annex ZA (informative) describes the relationship with EU Directive 2008/57/EC and how compliance can confer a presumption of conformity when cited in the Official Journal of the EU.
- Scope and stewardship: developed by CEN/TC 256 (Railway applications) and published in English/French/German.
Practical applications
- Manufacturers of railway lubricating greases use EN 12081 to design, test and document greases suitable for axlebox bearings.
- Rolling stock OEMs and axlebox/rolling-bearing suppliers reference the standard for component specification and procurement.
- Maintenance organizations and operators apply the standard’s quality and monitoring requirements to select approved greases and set maintenance regimes.
- Notified bodies, certification authorities and national standards bodies use the standard (and Annex ZA) for conformity assessment aligned with EU interoperability directives.
- Asset managers benefit from standardized grease selection to improve bearing reliability, reduce failures, and support cross-border interoperability.
Who should use this standard
- Lubricant formulators and manufacturers
- Wheelset and axlebox component suppliers
- Rolling stock designers and OEMs
- Railway maintenance planners and operators
- Certification bodies and conformity assessors
- National standards organizations and regulatory authorities
