It is published for the needs of the European Aerospace Industry. It has been technically approved by the

    5、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 revi

    6、ew 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 transformation to full European Standard (EN). The CEN national members have then to implement the EN at national

    7、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 published by ASD-STAN for the needs of the European Aerospace Industry. The use of this standard is entirely volun

    8、tary, and its applicability and suitability for any particular use, including any patent infringement arising therefrom, is the sole responsibility of the user.” ASD-STAN reviews each standard and technical report at least every five years at which time it may be revised, reaffirmed, stabilized or c

    13、d specifies the required characteristics for single-pole, arc fault circuit breakers rated currents from 3 A to 25 A, switching capacity 65 In, for use in aircraft electrical systems. Their operating temperatures are between 40 C to 85 C at a maximum altitude of Z = 15 000 m. The thermal protection

    14、is temperature compensated and operates between 55 C and 125 C. These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action “trip-free“ tripping. They will continue to function up to the short-circuit current. 2 Normative references The following documen
