European foreword
This document (EN 6099:2021) has been prepared by the Aerospace and Defence Industries Association
of Europe - Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this Standard has
received the approval of the National Associations and the Official Services of the member countries of
ASD, prior to its presentation to CEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2021, and conflicting national standards shall
be withdrawn at the latest by September 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,
Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

Introduction
This document is published at edition P2. Former editions P1 draft may exist for Airbus development
only but without any ASD-STAN official publication. In consequence configuration management
discrepancies with these unofficial documents are under Airbus responsibility.
1 Scope
This document specifies the required characteristics, inspections and test methods, quality assurance,
conditions for qualification, acceptance and delivery of rod-ends with self-aligning bearings metal to
metal designed to withstand slight swivelling under load. They are intended for use in fixed or moving
parts of the aircraft structure and their control mechanisms.
This document is applicable to all rod-ends with self-aligning bearings metal to metal. It may be applied
when referred to in a product standard or in a design specification.
