HALT & HASS
HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) for evaluating product reliability of all industries. Through HALT, the temperature and vibrations are raised for hostile testing for critical areas like aircraft. Through this testing, the simulation helps in eliminating any chance of failure.
This testing is being used by major manufacturing and R&D organisations to improve product reliability.
Combined Temp and Vibration: -100 C to +200 C with Ramp Rate of 70 deg/m
Vibration: 6 degree
Thermal Shock
The thermal shock test is an accelerated test that identifies failure modes caused by rapid temperature changes.
STD:
Protection against penetration of dust & water
The IP code or ingress protection code indicates how well a device is protected against water and dust.
STD:
Range:
Tropical Exposure Test
The Tropical Exposure test is a type of humidity test that helps determine the corrosion rates in materials. The test involves exposing the material/product to various environmental factors such as temperature and humidity.

Corrosion (salt mist) Test
Salt spray testing is a corrosion test that is used to evaluate the effectiveness of a coating as a protective finish. The test involves exposing coated samples to a high-saline environment that produces a corrosive attack on the samples. The appearance of corrosion products (rust or other oxides) is then evaluated after a pre-determined period of time.
