11、electrical network of aircraft and particularly use in non-pressurized areas. This cable family is used at operating temperature between 65 C and 260 C. These cables are demonstrated to be arc resistant for both networks (115 V and 230 V). It shall also be possible to mark these cables by qualified

12、compatible marking. These markings shall satisfy the requirements of EN 3838. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
