5、 Steckverbinder 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
6、 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 examination and
7、 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 level by g

With the connectors unmated the process for cleaning should include: 1) With the contacts remaining in the connectors use a lint free tissue or
27、 gleaning prob wetted with a suitable accepted cleaning solution to wipe the end face of the contacts. 2) Remove excess cleaning fluid with aerosol free agent dry air. 3) Mate the connector halves. The cleaning procedure is the same for male and female inserts in either plug or receptacle. Copyright
