5、 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 approved by the experts of the concern
6、ed 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 examination and review by users and formal
7、 agreement of ASD-STAN, it 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 national level by giving the EN the status of
8、a national standard and by withdrawing any national standards conflicting with the EN.

32、806.” By “Minimum tensile strength test load and double shear test loads and tension fatigue test: apply the coefficient 0,806.” The coefficient 0,806 is the ratio of UTS 1250/1550 and should be used for double shear and tension fatigue test too. The symbols inside and above of the drawing for roughness are not valid anymore. Add Ra max for each value Modify symbols according to ISO 1302. Replace MIL-C-83488C By MIL-DTL-83488 or EN 6118 Reference to EN 6118 is added as an alternative. The issue letter of MIL-DTL-83488 is removed.
