4、It is published for the needs of the European Aerospace Industry. It has been technically approved by the experts of the concerned Domain following member comments. Subsequent to the publication of this Prestandard, the technical content shall not be changed to an extent that interchangeability is a
5、ffected, physically or functionally, without re-identification of the standard. After examination and review by users and formal agreement of ASD-STAN, the ASD-STAN prEN will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) for formal vote and transfor
6、mation to full European Standard (EN). The CEN national members have then to implement the EN at national level by giving the EN the status of a national standard and by withdrawing any national standards conflicting with the EN. ASD-STAN Technical Committee approves that: “This document is publishe
7、d by ASD-STAN for the needs of the European Aerospace Industry. The use of this standard is entirely voluntary, and its applicability and suitability for any particular use, including any patent infringement arising therefrom, is the sole responsibility of the user.” ASD-STAN reviews each standard a

15、1 Scope This European standard specifies the characteristics of adjustable rod ends consisting of: a spherical plain bearing, metal to metal, in corrosion resisting steel, wide series (EN 4265); a rod-end with threaded shank with an optional longitudinal groove for locking purposes. They are intende
16、d for use in fixed or moving parts of the aircraft structure and their control mechanisms. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
