A highly accelerated stress test (HAST) is an essential part of environmental testing that combines high temperature, high humidity, pressure, and time to test a component’s reliability under harsh environments. HAST is an efficient and faster alternative to traditional temperature-humidity testing for testing moisture penetration in semiconductors, thin-film resistors, solar panels, pharmaceutical products to reveal corrosion failures due to packaging, materials, seals, and joints. A higher amount of stress and pressure better simulates the effects of humidity and temperature in the laboratory and helps predict component failures within days. HAST testing is also employed in transportation, packaging, and shelf-life studies of products. HAST tests under the same temperature, humidity, and pressure variables are performed in testing labs with voltage bias (BHAST) to accelerate moisture penetration and related induced failures within the device or product.
Our testing labs are well equipped to carry out Highly Accelerated Stress Test (HAST) and provide the best results to our clients based in the USA and other parts of the world. We at Infinita Lab perform not only routine tests, but also custom tests designed in our testing labs as per the client’s specific requirements.

We at Infinita Lab provide environmental tests as per the requirements of our clients. HAST testing services are used to measure the ability of materials to function under harsh environmental conditions.
HAST covers various tests that measure the ability of materials to function under stressors. The cost of a test depends on the type of test and the industry. For instance, HAST for boards starts from $840 for 96 hours.
HAST involves the application of extreme stress for a short duration instead of low stress for a long duration (which happens in natural conditions) to observe the resistance of materials to these stressors. Usually, HAST combines high temperature, humidity, and pressure to test a component’s reliability under harsh environments.
HAST testing is used for determining the resistance of materials to harsh environmental conditions. It is a more efficient and faster alternative to traditional temperature-humidity tests. It determines moisture penetration in semiconductors, thin-film resistors, and solar panels. It reveals corrosion failures resulting from packaging, seals, and joints. HAST testing is also used in transportation, packaging, and shelf-life studies of products.
