It is published for the needs of the European Aerospace Industry. It has been technically
6、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 affected, physically or functionally, without re-identification of the standard. After exam
7、ination and review by users and formal 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
8、 level by giving the EN the status of a national standard and by withdrawing any national standards conflicting with the EN.
