Weiber UV Accelerated Weathering Testeris one of
the common names and is widely used amongst
majority of labs across globe. Weiber UV Accelerated
Weathering produces accurate results through
interpretation or data for researchers for them to
evaluate the products or an article’s properties along
with performance with concentration onany of the non-
ferrous, organic, rubber, plastic and building materials
which help researchers to innovate or improve their
product qualities.Only 4.6% part of the solar spectrum
is represented by the UV radiations, but UV radiation
causes the most important damage to the polymeric
materials such as the rubber or plastics. The complete
UV spectrum ranges 280 to 400 nanometres, but the
most aggressive part is the UV-B range having very
short wavelengths 280-315 nanometres. As UV-B
range represents the shortest wavelength the tester
reproduces damage that may occur over months or
even years outdoors, Ultraviolet Light causes almost
all the photo-degradation to material exposed
outdoors. Mainly the weathering tests performed are
based on the regular observation of characteristics

reflecting an ageing process such as Mechanical
Properties: Elongation at break, tensile properties or
impact strength or
Visible Characteristics: includes crack formation,
chalking, changes in colour or gloss.
Weiber UV Accelerated Weathering Tester is the best
available simulation of short-wave sunlight than any other
aging chambers. It comes in handy for comparing the
performance of various types of polymers and stabilizers
and also considered the best products for correlation
studies. Moisture Simulation Products outdoors can be
exposed to moisture, in the form of dew, for up to 15hours
per day. Considering all features the chambers also
provides a rigorous, yet highly realistic, moisture exposure
with cycles of hot condensing humidity. The chambers can
be pre- programmed to simulate the effects of rain, such as
thermal shock and erosion.

Chamber Body: Double walled cabinet with inner
chamber made from Stainless steel of grade SS 304
and outer wall structure comprises of heavy gauge
PCRC steel sheet which is degreased and pre-
treated with primers inorder to avoid rusting
Insulation: Weiber Environmental Growth Chamber
provides cellular insulation that is through
polyurethane foam where it follows a rigorous process
of either retardation ,reduction of heat loss or heat gain
for energy conservation.
Cellular Insulation: comprises of air or various other
gases contained within foam of stable small bubbles
and formed into boards, blankets, or hollow cylinders.
Heating: Customised options available for setting up
positive temperature through stainless steel sheathed
air heaters, these heaters protect the test specimen
directly as they are placed in conditioning plenum
proving indirect heat.
Air Circulation: Sufficient air circulation efficient
motor fans are installed in order to ensure uniform
temperature throughout the chamber.
