Product details

HALT/HASS (Highly Accelerated Limit Test / Highly Accelerated Stress Screen) are tests for quickly detecting product weaknesses in product development and quickly eliminating potential defects in the manufacturing process. Product reliability can be improved by repeatedly detecting weaknesses and making improvements. Invented in the United States in the 1980s, HALT/HASS has been adopted as a reliability evaluation tool for aircraft, automobiles, and electrical products across Europe and the United States.

Product Robustness Improvement

Unlike the DVT (Design Verification Test), which checks the product by imposing a load under the conditions of use of the product, we give the product “strong stress” (rapid temperature change and 6-DOF vibration) that exceeds the product specifications and find the weakness. Improve product robustness by eliminating weaknesses.

Shortened Development Period

By discovering and improving latent defects in the development phase, we reduce the risks that occur in the post-process and shorten the development period.

Reduction Of Product Warranty Costs, Etc.

By taking measures against potential defects, it is possible to prevent troubles after market release, and reduce the total cost of products, including warranty costs.
