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

and therefore not approved for use in production. ST is not responsible for any consequences resulting

from such use. In no event will ST be liable for the customer using any of these engineering samples in

production. ST’s Quality department must be contacted prior to any decision to use these engineering

samples to run a qualification activity.
