EMC TESTing 

DA-Group offers electromagnetic compatibility (EMC) and RF testing, both for product development and for accredited verification testing. In our testing laboratories and Full Compliance  and Pre Compliance EMC testing chambers, a variety of services are offered:

• Radiated emission measurements
• Conducted emissions measurements
• Radiated susceptibility/immunity tests
• Conducted immunity tests
• Electrostatic Discharge (ESD) immunity tests
• Electrical fast transient (EFT) and Surge voltage/current immunity tests
• Voltage dips, short interruptions and voltage variations immunity tests

In addition, we perform other electrical, electroacoustic and RF measurements, such as radio equipment (WLAN, Bluetooth, 2G, 3G, 4G) and global navigation satellite system (GNSS) tests and measurements. 

ENVIRONMENTAL CONDITIONS TESTING

All common types of tests are offered, as such humidity and temperature tests as well as thermal shock and cycling tests.

To measure products' operations in extreme conditions and in an aging process, we have special testing equipment, such as solar simulator, UV testing and salt mist.

• Environmental testing (humidity and temperature), wide temperature range (-80 - + 180 °C) and damp heat test
• Thermal shock tests
• Thermal cycling tests
• Thermographic camera imaging

Thermal shock occurs when devices are forced to undergo rapid temperature changes between extremes. Temperature swings can cause materials to become brittle or cause damage. We utilize a variety of test chambers capable of rapidly altering the temperatures of test devices.

MECHANICAL TESTING

Mechanical shock tests can determine the suitability of a device for use in electronic equipment that is subjected to moderately severe shocks from rough handling, transportation or field operation. Mechanical shock testing utilizes shock and drop testing and is considered destructive. Vibration testing determines the extent to which items can withstand mechanical vibrations. 

• Vibration and free-fall tests with a high-speed camera
• Sine vibration tests
• Shock tests
• Random vibration tests

For any piece of mobile equipment to be functional, it needs to withstand some vibration. Equipment designed for rugged or hostile environments needs to withstand a lot of vibration without breaking down or wearing out prematurely. The only way to know, if something will withstand its intended application, is to test it appropriately.
