3、osion (paisser de paroi 0,25 mm) This “Aerospace Series“ Prestandard has been drawn up under the responsibility of ASD-STAN (The AeroSpace and Defence Industries Association of Europe - Standardization). It is published for the needs of the European Aerospace Industry. It has been technically approv
4、ed 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 affected, physically or functionally, without re-identification of the standard. After examinatio
5、n 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 transformation to full European Standard (EN). The CEN national members have then to implement the EN at
6、 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 published by ASD-STAN for the needs of the European Aerospace Industry. The use of this standard is enti
7、rely 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 and technical report at least every five years at which time it may be revised, reaffirmed, stabi
8、lized or cancelled. ASD-STAN invites you to send your written comments or any suggestions that may arise. All rights reserved.

25、ch sleeve shall only be designated as in the following example: Where the following codes apply: P = plain form G = grooved form NOTE If nessesary, the originator code S 9005 may be introduced between the description block and the identity block. 6 Marking EN 2424, style G. In addition, the quantity
26、 shall be stated on the package. 7 Technical requirements 7.1 Manufacture The sleeve shall be formed by a drawing process from sheet or strip stock to form a one piece tubular section and head. 7.2 Surface appearance The sleeves shall be free from cracks, seams and laps.
