8.4 Performance check
The performance check is to verify that the EUT is still operational after being subjected to the environmental tests and any other test where it is specified.
The performance check shall ensure that the EUT meets all necessary requirements including:
- reselection of field of view if available;
- pan range;
- pan speed;
- vertical trim adjustment;
- sensor.
The equipment should provide a clear picture of objects consistent with that at ambient conditions.

10 Sea Trials
10.1 Standard test target
The standard test target should be an encloses dark metal box, with one side at right angles to the desired direction of detection, which has been immersed in the sea for at least 24 hours.
The size of the box is such that when at least 80 % is immersed, 1.5 m long × 1.5 m wide × 0.5 m high remains above the water.
Administrations may use other smaller targets to reflect local conditions.
10.2 Minimum detection range
With the required field of view, the equipment should detect the standard test target at a minimum of 600 m with a minimum probability of 90 %, under mean starlight conditions without clouds and without moon.
