Procurement specification is principally for defining protection sleeves on a cable or group of electrical/fiber optic wires (wiring bundle). Single wire protection depends on the minimum diameter of the wire. Sleeve may be used to protect a wire bundle for a platform installation or for repair of installed damaged jacket or jacket/shielded wire bundles. See AS50881 for aerospace wire bundle protection installations.
LIMITED SCOPE CHANGE: It was brought to the committee’s attention that there was a Water Repellency requirement and test missing from AS60491. Three of the five detail specification sheets call out, "Sleeve shall be treated with a water repellent coating." This testing is critical due to the potential increase in weight and volume of the protection sleeve due to absorption of a fluid. RATIONALE: AS60491A adds missing water repellency requirement and test method.
