Most manufacturers boast that their products are the best in the market. However, consumers won’t easily purchase their products no matter how good their marketing schemes are if the product doesn’t meet the consumer requirements. The best option for manufacturers to provide proof that their products are reliable and safe is for their products to undergo product safety testing.
Product testing is a vital quality assurance process that is implemented during the production process. There are various procedures for product safety testing that products need to go through. One of these procedures is known as HASS testing.
HASS Testing: Finding Product Defects
HASS or Highly Accelerated Stress Screening is a procedure that is done during the development stage of the manufacturing process. During this procedure, any defects that can cause product failures are detected. This procedure is very effective in finding failures that may have gone unnoticed during the traditional testing stages.
The HASS testing will push the product past the specification to find any weaknesses. This means that the merchandise will need to undergo extreme temperature, rapid thermal cycling, and vibration testing- usually at the same time, to find any design weaknesses. The main goal of this testing procedure is to maximize the stress applied to the product, reduce the screening time, and make sure that the products will remain intact and undamaged. This procedure is very important for testing devices used in medical, avionics, and defense industries. Despite all these, the HASS testing still uses lower stress levels as compared to HALT. As compared to the HALT testing, the temperature and voltage used in this procedure is reduced by about 10-15%. HASS is not a standardized, prescriptive product safety testing procedure, but it is an optimized engineering solution.
Why HASS Testing Is Done
HASS testing is used to verify and make sure that the products will be able to offer the performance it promises. This procedure is done to know if there are any shifts in the interior performance of the product during the manufacturing process. It is also essential for this procedure to be performed by a company that specializes in accelerated life testing. Among the main benefits of Product testing are:
Reduce the time during product development and design
The merchandise are released sooner into the market
The superior quality and efficacy of the product is assured
Increase the satisfaction and confidence of consumers
Lower product recalls and warranty costs
Higher returns and profitability
