The main function
The UV-accelerated aging test chamber uses imported UVA-340
fluorescent UV light as a light source to simulate the damage
caused by sunlight, rain and dew. The UV weatherproof box uses a
fluorescent UV lamp to simulate the effect of sunlight, and uses
condensed moisture to simulate dew.
The material to be tested is placed in a cyclical program of
alternating light and moisture at a certain temperature to
accelerate the weathering test of the material to obtain the
weather resistance of the material. The UV box can reproduce the
hazards of outdoor months or years in days or weeks. Types of
hazards include: fading, discoloration, loss of light, powdering,
cracking, turbidity, air bubbles, embrittlement, strength, decay,
and oxidation. This machine contains a shower device.

J2020, ISO 4892 All current UV aging test standards.
Light source:
The light source uses 8 imported UV fluorescent lamps with a rated
power of 40W as the light source. Ultraviolet fluorescent tubes are
distributed on both sides of the machine, 4 on each side.
There are UVA-340 and UVB-313 light sources for users to choose
from. The luminescence spectrum energy of the UVA-340 lamp is
mainly concentrated at the wavelength of 340 nm, and the
luminescence spectrum of the UVB-313 lamp is mainly concentrated
near the wavelength of 313 nm.
We use UVA-340 lamps because the fluorescent light energy output
will gradually decay with time. In order to reduce the impact of
the test due to the attenuation of light energy, this test chamber
is 1/4 of all eight lamps. In the life of a fluorescent lamp, an
old lamp is replaced by a new lamp, so that the ultraviolet source
is always composed of a new lamp and an old lamp, thereby obtaining
a constant output of light energy. The effective life of the lamp
can be 1600 hours
