適用范圍：1.1 This standard specifies current rating data for cables produced with conductors as defined in EN 2083.1.2 Electrical ratings for continuous and short term conditions are tabulated such that the requirements ofEN 3197 are satisfied.1.3 A procedure for establishing cable current ratings is given in Annex B of this specification.1.4 The basis for determining current of cables has been to employ a 40 °C rise as the electricalcontribution to operating temperature. Note is made in this standard that, in practice, the voltage droprequirements of EN 2282 will often dictate lower current densities. Additionally, reference to appropriateaerospace series standards for cable terminations and connectors will show constraints which may dictatecable size.1.5 It is stressed that the current ratings given in this document relate solely to copper and copper alloyconductors as defined in EN 2083. The values are based upon historical evidence and are subject to thecaveat given in 4.1. Accordingly the acceptance of data without verification in any particular case is a matter ofdiscretion by both the aircraft design and certification authorities.
