1. Parts marked as “ES”, “E” or accompanied by an Engineering Sample notification letter, are not yet

qualified and therefore not yet ready to be used in production and any consequences deriving from such

usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering

samples in production. ST Quality has to be contacted prior to any decision to use these Engineering

samples to run qualification activity.
