Environmental test method for civil light and small UAV system
Part 8.Salt spray test
1 Scope
This part of GB/T 38924 specifies the civil light and small unmanned aerial vehicle (take-off weight 0.25kg~150kg) system (including aircraft and
Ground station) test conditions, test equipment and instruments, test process, test interruption and recovery, test result evaluation and test report in salt spray environment.
This part is applicable to civil light and small drones that will be affected by salt spray during storage and use (take-off weight is 0.25kg~
150kg) system (including aircraft and ground station) to determine that the civilian UAV system is exposed to the salt spray atmosphere for a long time or is in normal use
The ability to withstand salt spray atmosphere.
