Who should attend?

I need to become familiar with HALT and HASS because:
  • I am a manager in product design and development and/or manufacturing
  • I am an electronic, mechanical, design, reliability, production, quality, and/or test engineer
  • I am a technician who needs to gain understanding of what is required for proper test implementation

This Recommended Practice (RP) defines and describes HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening). This RP contains information on the philosophy behind the testing, generic examples of tests, the differences between standard testing equipment and equipment used for highly accelerated testing, fixturing considerations, alternative approaches, additional environments, and lessons learned, along with other useful information. This style of testing takes a qualitative approach (looking for the quality of the design and workmanship) rather than a quantitative one (being able to use the results to calculate length of life in service). This RP is not meant to take the place of a test specification but to be used in conjunction with a test specification or as general guidance.
