WebThe Unbiased HAST is performed for the purpose of evaluating the reliability of non-hermetic packaged solid-state devices in humid environments. It is a highly accelerated test that employs temperature and humidity under noncondensing conditions to accelerate the penetration of moisture through the external WebThis is where high altitude simulation testing (also called HAST, hypoxic altitude simulation testing or a hypoxic challenge test) comes into play. Done before you get on a plane or travel to a high altitude area, high altitude simulation testing checks to see how well your lungs can handle a slightly reduced oxygen concentration. Based on your ...
