An acronym for Highly Accelerated Stress Screen. HASS tests are less extreme versions of HALT tests that are conducted on manufactured product before it ships to the customer.

Highly accelerated stress screening. A technique for production screening that rapidly exposes process or production flaws in products. Its purpose is to expose a product to optimized production screens without affecting product reliability. Unlike HALT, HASS uses nondestructive stresses of extreme temperatures and temperature change rates with vibration.

Highly Active Sealed Source. HASS is any radioactive sealed source containing more than one-tenth of the A1 value in the IAEA Regulations for the Safe Transport of Radioactive Material.

Hass is a cultivar of avocado with dark-colored, bumpy skin. It is correctly pronounced like "hassle", not the commonly misspelled "Haas".
