Environmental testing
As well as being a requirement in many standards' type and approvals tests, environmental testing is a development tool for troubleshooting and for proving product integrity.
UL Australasia's Christchurch laboratory includes instrumentation and equipment that meets the requirements of the IEC60068 series and other technically equivalent standards for the following range of tests:
- Cold tests down to -78C
- Dry heat tests up to 200C steady state
- Damp heat tests -78C to 170C (30-95% relative humidity)
- Thermal shock testing
- Highly accelerated life testing
- Impact tests
- Acceleration tests
- Corrosion tests
- Change of temperature tests
- Sealing tests
- Altitude tests
- Ingress protection
Shock and vibration to IEC 60068 and MIL-STD-810 series or technical equivalents.
UL can test to the following specifications:
- Sine sweep tests
- Computer controlled endurance tests running from 5Hz to 4000Hz
- Fixed frequency sinusoidal vibration
- Sine on sine and sine on random vibration tests
- Displacement, velocity and acceleration fixed frequency
- Random vibration tests
- Shock tests with various waveshapes, pulse widths and peak accelerations:
- Up to 75g shock loading
- Conducted in up to six axis directions.
- AGREE testing (Combined vibration and temperature environments)
Testing capabilities and limits are dependent on size and weight of test specimen
