Environmental Test Engineering

With the existing climatic test technology, test specimens and components can be exposed to various climatic, even changing loads. Both temperature and humidity can be specifically adjusted and varied. A thermal shock chamber is available for particularly rapid temperature changes. The test chambers are designed and equipped so that e.g. samples, components or assemblies can be supplied with the appropriate media (e.g. electrical, pneumatic, hydraulic, etc.) during climate loading. Other environmental influences such as salt exposure, UV radiation and weathering can be simulated and tested (also according to standards)  using appropriate test equipment.

Temperature Shock Chamber

Temperature Shock Chamber

Manufacturer:Feutron Klimasimulation GmbH
Model:TSK 200

The temperature shock chamber is a combination of two temperature chambers, which are connected by a movable rack and used alternately.
The test material is subjected to rapid temperature changes by being alternately exposed to low and high temperatures. The degree of test severity depends on the two chamber temperatures, the transfer time and the number of cycles.
Each chamber provides with a viewing window for visual monitoring. For measuring and supply lines such as compressed air, electrical or hydraulic, appropriate feedthroughs and entrances are available in each chamber as well as in the rack.

High-Performance Safety drying Oven

High-Performance Safety drying Oven

Manufacturer:Binder GmbH
Model:MDL-115 with coil coating extension

This high-performance drying oven operates in the temperature range up to 350 °C with an air throughput of up to 400 l/min. Due to the integrated coil coating drawer, it is ideally suited for the simulation of hot air short cycle or coil coating applications. The heating capacity is 9 kW for a furnace volume of approx. 115 liters. The MCS controller can store 25 programs with 100 sections each for a maximum of 500 program segments.

With the coil-coating drawer, the oven is particularly suitable for very rapid heating of test specimens and short heating cycles. Due to the programmable control and the high heating power, even demanding temperature control and cooling programs (based on the ambient temperature) can be carried out, e.g. curing or drying processes with defined temperature control.

Salt Spray Chamber / Corrosion Test Chamber

Salt Spray Chamber / Corrosion Test Chamber

Manufacturer: Köhler Automobiltechnik GmbH
Model: HKT1000 WKT

In industrial practice, the salt spray test (SST) is a frequently used test method for proving the product quality of semi-finished products with regard to their corrosion resistance. The more stringent test conditions compared to the "natural" process have the advantage of shortening the test time, but also the disadvantage of the possibly affected corrosion mechanism.
Standard-compliant salt spray tests are carried out.

Possible Operating Modes for accelerated Corrosion Tests:
•  salt spray test
•  condensation test
•  constant and alternating climate test
•  condensation water test
 

Application Examples:
•  Testing of coatings on metal substrates (with and without scratch) to determine the maximum loading time
•  Comparative investigations on the quality of coatings by means of intermediate tests with increasing loading time
•  Evaluation of delamination, bubble formation, corrosion starting from the scratch
•  Evaluation white rust for zinc, filiform corrosion for aluminum


Possible Testing Standards:
DIN EN ISO 4611
DIN EN ISO 6270-1 / -2
DIN EN ISO 9227
DIN EN ISO 11997-1 / -2
ASTM B 117
DIN EN 60068-2-11
ASTM G-85

 

Device Configuration:
•  Operating settings:
   –    Test chamber volume: 1000 l
   –    Climate area: RT +5 °C to 60 °C
•  Stable conditions due to dosing pump
•  Freely programmable test conditions

Weathering Testing

Weathering Testing

Manufacturer:Atlas GmbH
Model:Beta +

The test device simulates natural weathering and provides reliable information on the weather resistance of all materials within a short time.

It is suitable for testing light and weather resistance of many materials and coatings.
Due to the double irradiance – 2 suns: up to 120 W/m² – compared to normal sun exposure on earth, UV weathering tests can be reduced to half the usual time.

Device Configuration:
•  3 air-cooled xenon lamps (à 2200 W)
•  4000 cm² sample area
•  Tests with high irradiance up to 120 W/m2 (2 times the irradiance of the sun)

                                              - Black standard temperature
                                              - sample chamber temperature
                                              - relative humidity
•  Ageing-stable XENOCHROME filters to simulate daylight outdoors and/or behind window glass
•  XENOSENSIVE on the sample carousel 300 - 400 nm for measurement and control of irradiance (in W/m2) and BST (°C) at sample level
•  Selectable temperature control either by sample chamber temperature (max. 70 °C) or double control: sample chamber temperature and black standard temperature (up to 130 °C)
•  Ventilator -controlled temperature difference between sample chamber and black standard temperature•    Ultrasonic humidification system for humidity control
