Product Code:SAE ARP5475
Title:Abuse Load Testing for In-Seat Deployable Video Systems (STABILIZED Nov 2011)
Issuing Committee:Aircraft Seat Committee
Scope:This SAE Aerospace Recommended Practice (ARP) provides guidelines for abuse load testing of a deployable Individual Video System (IVS).The abuse load testing defined in this ARP is intended to only address the evaluation of the deployable IVS regarding stowage of the system and injurious projections/protrusions as a result of passenger interaction with the video system. Other aspects of the video system design or qualification may require additional testing or analysis and are outside the scope of this ARP.This ARP is not intended to address customer satisfaction or reliability aspects of individual designs.The deployable IVS includes, for the purpose of this ARP, all video system components from the monitor to the interface at the primary seat structure. It should be shown that the system meets the performance criteria of Section 4 after being subjected to the forces defined in 3.2. This can be demonstrated by the test procedure described in this ARP or by similarity analysis to a system previously shown to comply with this ARP.
