1 Measuring device for dust and sand test

Gives general design characteristics for lighting controllers to supply electric filament lamps used in aircraft instruments and for the illumination of panels, operating from nominal 28V d.c. and 115V a.c. 400 Hz aircraft supplies. Includes markings details, performance type tests, environmental tests, production acceptance tests, production quality tests and dust and sand test. Illustrates a measuring device for dust and sand test.

This British Standard specifies general design characteristics for lighting controllers to supply electric filament lamps used in aircraft instruments and for the illumination of panels, operating from nominal 28 V d.c. and 115 V a.c. 400 Hz aircraft supplies.
