Delserro Engineering Solutions Featured in Assembly Magazine

Assembly Magazine logo

DES president Gary Delserro is featured in an article published in Assembly Magazine on July 9, 2021.  Titled “Accelerated Life Testing,” the article discusses different types of manufacturing life testing and quotes Gary with reference to highly accelerated life testing (HALT):

“Companies have reported savings in the millions after using HALT,” claims Delserro. “The test can accelerate a product’s aging process from actual months into test minutes, and it can help you discover weaknesses in your product during the design stage. Combined vibration, temperature and electrical stress variables, as well as internal fluid pressure, are typically used during HALT to induce failures and uncover fault points. By using combinations of loads, we can uncover design or manufacturing process flaws before they reach your customer.”

What Exactly is MIL-STD 810?

MIL-STD 810 is a Department of Defense Test Method Standard for environmental engineering considerations and laboratory tests.  It is the most popular Military specification used to conduct environmental testing of military products.  It exists so as to ensure that products used for defense-related purposes meet very specific requirements with regard to ruggedness, durability, and performance.  Given the fact that these products may be exposed to harsh or even extreme conditions, their reliability under stress is essential

HALT Testing: When Should You Perform It?

Highly Accelerated Life Testing, or HALT, is a technique used in the industry to speed up the design and test phases of product development, as well as limit the number of field failures and thus reduce warranty costs incurred by the manufacturer. 

HALT Testing can be a competitive advantage for companies when performed correctly and at the right time. 

The best time to begin HALT testing during the product development process is when prototypes first become available. HALT is designed to expose product flaws and weaknesses, therefore, a successful test will produce areas for product improvement.  A lot of designers and manufacturers tend to wait until the product design is mature.  At that time, further process improvements or design changes become too costly or timely.  Ideally, HALT should be performed while the product is still fluid and moderate changes don’t become setbacks.  This allows product design to move much more rapidly and efficiently, saving the company time and money.  HALT testing can also eliminate the need for further verification if the product has proven reliable at the much more extreme conditions exposed to in HALT. 

Delserro Engineering Solutions, Inc. (DES) has the knowledge and experience to provide HALT testing services for your product.  We offer both standard and customized test solutions depending on your testing needs.  For more information on HASS, HALT or other testing services, contact DES or call 610.253.6637.

Salt Fog or Salt Spray Testing

Salt fog (aka salt atmosphere or salt spray) testing exposes components to a fine salt fog mist that can result in rusting or corrosion of susceptible materials.  Samples to be tested are hung or placed on a rack inside of the salt fog chamber at the orientation that is specified in the applicable test method or otherwise agreed to with the customer.  The orientation during testing is important as unintended corrosion can result if the salt fog is allowed to condense and pool on the sample.  The samples are then exposed to a salt fog of defined salt content.  The salt solution used to provide the salt fog mist is usually a 5 percent by weight NaCl solution with the pH adjusted close to 7.0.  The salt fog condensate rate is monitored during the test to verify that the test requirements are met.

DES Performs Testing for NASA Psyche Program

NASA Psyche ProgramDelserro Engineering Solutions (DES) was proud to recently perform testing for the NASA Psyche Program.  More information about this program can be found at the following web link

DES was contracted by a local manufacturer to help qualify their product for use in the demanding Psyche spacecraft environment. DES’s role was to perform specialized pyroshock testing and vibration testing on their products.

What sets DES apart from other labs is our in-depth experience and technical capability to understand and reproduce the most complicated vibration and shock profiles. DES continues to perform the most complex vibration and shock tests on products that are used in outer space, rockets, missiles, automotive & truck environments, military environments, etc.

For more information on Pyroshock Testing, Shock Testing, Vibration Testing or other testing services, contact DES or call 610.253.6637.
