20、ectrical systems of aircraft operating at temperatures between 65 C and 135 C, operating at voltages not exceeding 600 V r.m.s and frequencies not exceeding 2 000 Hz. These jacketed cables are suitable for airframe use without additional protection when the jacket is present. When the jacket is stri
21、pped back the cores 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 referenced documents are indispensable for the application of this document.
