Equipment Overview
The aging test is carried out by exposing the material of the
samples (which including but not limited to automotive, coatings,
rubber, plastics, pigments, adhesives, fabrics, aerospace,
shipbuilding, electronics, packaging, etc.) to the illumination and
heat radiation of the xenon arc lamp, to evaluate the light and
weather resistance of some materials under the action of high
temperature light source.
Xenon arc lamps simulate full sunlight spectrum to reproduce
destructive light waves in different environments.

With 4 custom methods, users can set test parameters by themselves
to meet most common standard requirements. |
| Drum sample holder |
The rotating drum sample holder can ensure the excellent irradiance
uniformity of the upper, middle, and lower samples while taking
into account the sample volume. In addition, the sample
continuously rotates around the lamp tube with the sample holder to
further ensure uniform and stable irradiance, sample surface
temperature, and water spray. |

Questions & Answers
Q: What about the exposure area?
A:6500cm2/ About 65 standard samples (140mm×70mm)
Q: What is the Radiation Intensity of Xenon?
A:0.3 W/m2～1.1 W/m2(@340nm)
40 W/m2～120 W/m2(@300nm～400nm)
SN883-X65 can reach 2 of levels which close to the sun level .
Other domestic equipment is generally customized based on a certain
standard and does not understand the irradiance requirements of
different fields.
Q: What's the cooling system?
A:SN883-X65 can reach a higher power level to meet the needs of
current and future test development. There is cooling water flowing
between the filters, which can effectively reduce the infrared heat
to the sample surface. And reduce the generation of ozone, increase
the accurate matching with the external environment.
Cooling effect remark: water cooling is better than air cooling.
