Highly Accelerated Life Testing HALT and Highly Accelerated Stress Screening HASS

Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS) are product reliability testing processes that test a product’s design limitations and manufacturing weaknesses. HALT is performed on products and components during the design phase before production and HASS is performed when the product is ready for manufacturing. These tests evaluate any weakness that the product might develop during the manufacturing process. Infinita Lab experts devise the best strategies to perform accelerated life tests as per the requirements of clients based in the USA and other countries.

    Highly Accelerated Life Testing (HALT) and HASS Testing

    Both Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS) are product reliability testing processes that evaluate a product’s design limitations and manufacturing weaknesses. Both HALT and HASS testing methods are similar in approach. HALT is performed in testing labs on products and components during the design phase before production or manufacturing. HALT employs a stepped accelerated stress approach to identify the physical limitations of a product’s design under various stressors. HASS is performed when the product is ready for manufacturing. HASS testing has a similar testing approach as HALT to assess any weakness the product develops during the manufacturing process. Both tests are run to failure to acquire comprehensive data on failure modes and follow a root cause analysis approach to fix issues. Generating a HASS testing profile usually requires a previous HALT with robust product design and validation data. The type of stresses induced in HALT & HASS includes combined temperature cycling, random 6 degrees of freedom vibration, and electrical loading/monitoring.

    HALT and HASS testing for accelerated life tests can help designers and engineers address critical development and manufacturing issues ahead and avoid expensive redesign costs or production costs later in the product or component’s life.

      FAQs on Highly Accelerated Life Testing HALT and Highly Accelerated Stress Screening HASS

      Where can I get HALT and HASS testing of products done?

      We, at Infinita Lab, provide environmental testing to many startups and established companies throughout the USA to measure the ability of their products and components to function under harsh environmental conditions.

      How much do HALT and HASS testings cost?

      Highly accelerated life testing (HALT) and highly accelerated stress screening (HASS) cover various tests that measure the ability of materials to function under various environmental stress factors. The cost of a test depends on the type of test and the industry. Please write to us to know about the best quotes.

      What are HALT and HASS tests?

       HALT and HASS tests apply high-stress levels for short durations well beyond the expected field environment to identify the limitations of a product’s design under various stressors. They assess the reliability of a product by finding defects during the product development phase when changes are inexpensive to make. 

      What is the use of HALT and HASS testing?

      HALT and HASS are used to find design defects and weaknesses to help designers and engineers address critical development and manufacturing issues in advance, and avoid losses.
