Companies that develop products, software, or any unique service have to test whatever they’re offering to ensure that they perform as intended. Good thing, there are specific tests that can help in testing and finding problem areas to fix flaws. Two of these tests are the Highly Accelerated Life Test (HALT) and Highly Accelerated Stress Screen (HASS).
Understanding HALT and HASS
Both tests undergo in a lab under the supervision of a HASS consultant. Each test occurs at different stages of a product’s development.
The HALT test takes place at the initial stage (before production) to identify design weaknesses, so changes can be made. The HASS test takes place right at the production stage. Product samples are subjected to stress tests beyond the specified limit. This helps to determine if a product or service can meet its life expectancy without failure. Some of the products commonly tested by these tests are:
- All types of electronics
- Aviation related products
- Industrial products
- Marine products
The Role of a HASS Consultant
Being a HASS consultant is a highly technical job, as they’re involved in every step of the life cycle of a product. After HALT testing and the design looks robust, manufacturers start production. It is highly likely that new issues will crop up.
As production samples are different from the prototypes (due to changes from HALT), expect variations in production samples. HASS testing is instrumental in identifying potential production failure. It offers the engineering team a list of issues, which have to be remedied with corrective action. This helps to improve not only manufacturing but also put out a robust and reliable product.
It is essential to implement testing methods at every step, starting with design and ending in production. HALT, HASS, and other tests are available along with parameters in manuals specified by apex industry groups.
