HALT & HASS Testing

DNB offers HALT & HASS testing and consulting to help customers to discover design flaws by exposing the product to combined thermal, vibration, voltage stresses, and product life cycles.

HALT (Highly Accelerated Lifecycle Testing) and HASS (Highly Accelerated Stress Screening) methods can be used in a variety of industries, including electronics, computers, medical, aerospace, and military, and help to identify weaknesses in design or production. Both HALT and HASS are important testing methods to use before a product has been introduced into the market. The benefit of these methods for the customer is the ability to achieve stress level results quicker than with conventional environmental test methods.

What are HALT and HASS?

HALT, or Highly Accelerated Life Testing, is a testing process often known as Destruct Testing. During the HALT test, components and assemblies are subjected to rapid temperature ramp rates and six-axis random vibration stresses, which gradually increase until there is a failure. This failure is identified as a weak point in the design or material used. Once identified, product and material changes can be rugged into the product to improve overall quality. Often, these changes will improve the overall design and reduce the time spent in the development phase of the product lifecycle, effectively speeding the product’s time-to-market.

HASS, or Highly Accelerated Stress Screening, is a testing process that is performed on components and finished assemblies. HASS tests do not stress products to their destruct point. Instead, HASS testing identifies the upper and lower operational range of a product and allows for the opportunity to increase the operational range well beyond the product’s expected lifetime operational stresses.
