Other tests

We determine whether the tested equipment has any impact on its surroundings or the equipment itself, and whether it can endure the impact of its environment. The corrosion resistance of materials is also tested.

  • Electromagnetic compatibility testing.
  • Testing resistance of materials.
  • Noise measurement.
  • Refrigeration compressor testing.

EMC TESTS

Our specialist team provides electromagnetic compatibility (EMC) services, including:

  • Validation of your equipment and preparation for testing in an external certified test lab.
  • Measurement of the basic EMC parameters and implementation of necessary modifications to equipment to ensure compliance with stipulated certification parameters.
  • Testing equipment in an external certified test lab, including a test report, can also be arranged.

MATERIAL TESTS

Corrosion resistance testing is performed according to ISO, DIN, ASTM, CASS, and SWAAT standards, including assessment using optical microscopy methods.

The testing space volume in corrosion chambers is up to 1 m3. Chamber Liebisch (L1300 x W800 x H550 mm) and chamber Weis (L1560 x W510 x H740 mm). 

NOISE MEASUREMENT

  • Acoustic noise level measurement in the range: 20 Hz to 20 kHz.
  • Noise intensity measurement.
  • Acoustic power measurement in the range: 50 Hz to 6300 Hz.
  • Identification of noise and vibration sources.
  • Anti-noise measures and proposals for reducing vibration.

REFRIGERATION COMPRESSOR TESTING

The test lab has three areas for testing compressor performance using conventional or alternative coolants, including supercritical CO2 with a maximum output of 70 kW.

The test lab also has seven chambers for stress and lifespan testing of compressors with outputs up to a maximum 10 kW.

EMC MEASUREMENT

We carry out wide variety of EMC testing. If necessary, we can provide expertise on how to modify the equipment in order to make it compliant with mandatory standards. We focus on pre-compliance and development testing and provide our customers with high confidence of passing certification tests.
