WEISS Auto industry test chambers

Climate Test Chamber with Dynamometer

Performance determination and cold start tests with vehicles at defined
environmental conditions such as temperature, air humidity, air pressure,
wind speed, sunlight and rain.
These chambers are used for emission testing in accordance with
European and American regulations.
 Besides the sunlight simulation system for SFTP tests these chambers
are additionally equipped with an air makeup unit, a wind speed fan and
fuel tank heating by hot air blowing onto the tank surface.

Technical specification:
> Test space volume: 502 m3
> Temperature range: -20 ... +50 °C
> Humidity range: max. 75 % r.h. between +10 ... +35 °C

Airbag Test Systems

Walk In Airbag Chamber
The system comprises the temperature conditioning chamber, a sliding
test frame with runners, automatically closing gate and switch cabinet
with control system. The testing system is for testing the performance of
airbags at extreme temperatures.
Technical Specifications:
> Test space volume: 25 m3
> Temperature range: - 40 . . . +120 °C

Airbag Chamber
Airbag modules are tested in this chamber. The testing parameters are
temperature and humidity. The test specimen set-up is mounted on a
plate. The plate projects out of the test room and for this reason the door
of the test room is cambered. The door of the test room is opened and
closed pneumatically. Approx. 10 seconds is needed for opening and
closing the door.
Technical Specifications:
> Test room volume 500 litres
> Temperature range -70 … +150 °C
> Climate range +10 ... +85 °C
> Humidity range 10 ... 95 % r.h.

Testing of car-components

Endurance Strength Test Stand
The Endurance Strength Test is performed by fixing specimens onto a
2 x 2 m test bench in the temperature test chamber. This is dynamically
stressed under temperature influences via hydraulic servo actuators.
Conditioned air is supplied into the test chamber through ducts from
a remote conditioning system.
Combined Corrosion Testing System
 For vibration, climate and corrosion testing of axles, half axles and parts
of axles. The operating reliability test bench enables the combination of
the test parameters – temperature, humidity, corrosion with NaCl, CaCl
and MgCl solutions with simultaneous vibration in the x, y and z axes.
Cooling Cycle Test Stand
For testing and measuring the performance of complete vehicle air
conditioning systems (CO2 and R134a). Due to the transcritical working
conditions, the CO2 is cooled in a coaxial heat exchanger. It is also
possible to measure the torque at the compressor and the refrigerant
mass flow.
Endurance test stand for vehicle compressors
Vehicle components testing with cold splash water and Arizona dust
