HALT: HASS:

HALT testing reveals failure modes during product design phase. HALT testing exceeds normal operating levels, including simultaneous fast temperature changes and 5-axis randomized vibration. HALT testing enables faster correction and improved design margins resulting in increased lifetime and reliability.

HASS testing reveals defects during product manufacturing.

HASS testing is more rigorous than normal operating conditions but well below HALT conditions.

HASS testing is most effective when included in the standard production process.

HALT/HASS History

In the 1970’s, HALT/HASS testing was originally applied to space-related projects including opto-mechanical and electrical systems. It’s now widely used in aerospace, automotive, medical, and consumer industries. Coherent uses HALT/HASS to test our industrial lasers as well as to design and build scientific lasers such as Vitara, Astrella, Revolution, and Chameleon.
