Test 1 (Less strict)
The units under test (UUT) are placed in a closable plastic box (120 x 85 x 65 mm).
A ball of absorbent cotton appositely tinctured with solvent will be placed above the UUT; to avoid early evaporation,
a generic solid body will be put over the ball or, in a more simply way, the closable plastic box will be closed. After a 10
minutes wait, the eventually body and the ball of absorbent cotton will be removed; the solvent that remains on the
UUT will not be wiped off and the box will be closed immediately afterwards for 24 hours.
The test will be performed at environmental temperature (about 20°C).
Test 2 (Very strict)
The units under test (UUT) are fully and thoroughly wet by solvent, then will be closed into a closable box (120 x 85 x 65
mm) for 24 h. Approximately 5 ml solvent will be sprayed over the UUT. The box will be closed and the UUT will remain
in the closed box for at least 24 hours.
The test will be performed at environmental temperature (about 20°C).
Touchscreen test procedure
The Touchscreen is placed into a closable plastic box (120 x 85 x 65 mm) and a ball of a Base Station or bent cotton
appositely tinctured with solvent will be placed above it, then the box will be closed for 1 h.
The test will be performed at environmental temperature (about 20°C).
