4、sse R Produktnorm 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 exper
5、ts 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 examination and review by
6、 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 level by giving the
7、EN the status of a national standard and by withdrawing any national standards conflicting with the EN.

10、 from and interchangeable with those of standard SAE AS 39029/95. They are also interchangeable with those of standard EN 3155-043. 1 Scope This standard specifies the required characteristics, tests and tooling applicable to female electrical triaxial contacts, size 08, type D, crimp, class R, used
11、 in element of connection according to EN 3155-002. It shall be used together with EN 3155-001. The associated male contacts are defined in EN 3155-034 and EN 3155-042. 2 Normative references The following referenced documents are indispensable for the application of this document.
