DNB Chandler, Arizona Facility Expands Testing Services

DNB Engineering, Inc is a global leader and recognized expert in certification testing services. The company is dedicated to solving customer’s testing and engineering challenges within the Aerospace, Military, Commercial, Medical, and Automotive industries, and is adding Product Life Cycle Testing (HALT & HASS) Services at DNB Chandler, Arizona Facility to help customers improve product reliability.

The enhancements complement the ongoing capacity and capability expansions at DNB Chandler Arizona Facility, enabling the company to expand the reach certified testing services.

HALT (Highly Accelerated Lifecycle Testing) and HASS (Highly Accelerated Stress Screening) methods can be used in a variety of industries, including electronics, computer, medical, aerospace and military and help to identify weaknesses in design or production. Both HALT and HASS are important test 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 /or assemblies are subjected to rapid temperature ramp rates and six-axis random vibration stresses which gradually increase until such time as 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 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 life-cycle, 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.
