WebHAST is sometimes classified as a combined test when pressure is also considered as an environmental parameter. There are saturated and unsaturated varieties of HAST. The former is ty pically done at conditions of 121°C and 100% RH, and the latter at conditions of 110, 120 or 130°C and 85% RH. Tests done with the WebDuring THB proper, intermediate readpoints at 48H, 96H, 168H, and 500H are often used. This gives look-ahead reliability data as the THB test progresses.
