No. One of the most commonly used definitions of faith is trust or confidence in a person or thing. Whether or not that trust or confidence is based on evidence or not is a separate matter that is not conveyed by the word.
Even in the case under discussion, that someone might have faith that something is a particular way, and are doing an experiment to confirm it (more likely disprove an alternative), that doesn't mean it's 'blind' as in without reason. People can have a lot of good reasons for believing something is a particular way without having measured it directly yet.
