Subsequent to the publication of this Prestandard, the technical content shall not be changed to an extent that interchangeabi
7、lity is affected, physically or functionally, without re-identification of the standard. After examination 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
8、 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 a national standard and by withdrawing any national standards conflicting with the EN. ASD-STAN Technical Committee approves that: “This document is

15、ylene Tetra Fluoro Ethylene co-polymer (XLETFE) family for use in the on board electrical systems of aircraft operating at temperatures between 65 C and 135 C, operating at voltages not exceeding 600 V rms at sea level. This insulation system has been used in aerospace applications using 115 V (phas
16、e-to-neutral) 400 Hz ac and 28 Vdc. Verification of the suitability of cables for use in other electrical systems is the responsibility of the user. These jacketed cables are suitable for airframe use without additional protection when the jacket is present. When the jacket is stripped back the core
17、s may need additional protection. In case of conflict between this standard and other referenced documents the requirements of this standard shall take precedence. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes r
