The Xenon arc weathering chambers have automatic control of light<br />
intensity, temperature <strong>and</strong> humidity. Specific programs allow the samples<br />
to be sprayed with water or exposed to alternating cycles of dark<br />
<strong>and</strong> light periods.<br />

c) Q<strong>UV</strong> versus Xenon lamp testing<br />
Key characteristics Usual St<strong>and</strong>ards at <strong>Cabot</strong><br />
Q<strong>UV</strong> • Only match the short <strong>UV</strong> part of solar spectrum ISO 4892/3<br />
Fluorescent • Faster comparative results Light source : <strong>UV</strong> B (313nm)<br />
<strong>UV</strong> B lamps • Features : Light/ dark/ condensation/ Irradiance : 0.63 W/m2 at 313 nm<br />
no humidity control Cycle : 8 hours light at 60°C,<br />
4 hours condensation<br />
ATLAS • Emission spectrum closer to the entire solar ISO 4892/2<br />
Ci65A spectrum Referenced in the CEN norm for<br />
Xenon lamps • More "absolute" comparative results agricultural films<br />
• Features : Light/dark/spray/ Light source : xenon burner with<br />
condensation/humidity control 2 borosilicate filters<br />
Irradiance : 0.35 W/m2 at 340 nm<br />
Cycle: 102 min light (65°C,65%RH),<br />
18min light & spray<br />
