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 and air 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.

AIR COMPRESSOR TEST LAB

The air compressor test lab develops and tests the performance and characteristics of air compressors according to ISO 1217 Annex C and tests air compressor components. Precise measurement of airflow, electrical input, pressures and temperatures, vibrations, and oil residues in air are performed on the tested compressors. Highly precise gauges and unique technology are employed for measuring and testing.

The lifespan test lab for air compressors is designed for long-term performance testing and special tests under long-term operational conditions.

EMC MEASUREMENT

We offer the performance of EMC emission tests of all kinds, basic EMC immunity tests, ESD tests, and surge and burst tests according to main CE, CISPR and UNECE R10 standards and other specialized standards, for the equipment up to 400 V/32 A.

NOISE MEASUREMENT AND ANALYSIS

  • Measurement of Sound pressure level from 20 Hz to 20 kHz according to ČSN ISO 3744,
  • Acoustic Power 50 Hz to 6300 Hz in free field, inside according to ČSN ISO 9614,
  • Acoustic power to duct system
  • Identification of sources of noise
  • Design of noise suppression measures (machines and equipment, means of transport etc.)
