Development, Verification, and Validation of a Thermal Model for Determining Current Derating Design Limits of Aerospace Wires and Wire Bundles

2021-08-18
CURRENT
ARP7987
The thermal modeling guidelines and best practices provided in this document are applicable to powered aerospace vehicle wires and wire bundles in thermal environments ranging from -65 to +260 °C (-85 to +500 °F) and pressures ranging from sea level to space vacuum. Currently the ARP only considers steady state and direct current conditions. The effects of wiring terminations and connectors are not addressed. Both can significantly impact the overall current derating and safety margins for a wiring system.

Marking of Electrical Insulating Materials

2019-12-27
CURRENT
AS5942
This specification establishes the performance requirements for the identification of wire and cable by indirect markings that have been applied to electrical insulating materials including heat shrink sleeving, wrap around labels and “tie-on” tags as well as any other types of materials used for indirect marking. This specification covers the processes used to mark these materials, including impact ink marking, thermal transfer, hot stamp, and lasers, etc. This specification does not cover the direct marking on insulated electrical wires and cables.
