Different devices have different levels of sensitivity to electrostatic discharge, or ESD. Thus, there needs to be a way to distinguish ESD-sensitive devices from those which are not as vulnerable to ESD. Each of the ESD models used in ESD sensitivity testing has its own classification system for categorizing devices according to their ESD sensitivity.
Is-sensittività ESD ta 'apparat hija ġeneralment speċifikata f'termini tal-ogħla vultaġġ tat-test ESD li jgħaddi u l-inqas vultaġġ tat-test ESD li jonqos għal kull mudell ESD. Għalhekk, is-sensittività tal-ESD ħafna drabi hija espressa bħala firxa ta 'vultaġġ ESD li apparat jista' jiġi suġġett b'mod sikur għal kull wieħed mill-mudelli ESD. It-tabelli li ġejjin jippreżentaw il-livelli tal-klassifikazzjoni tas-sensittività tal-ESD definiti mill-Assoċjazzjoni tal-ESD għal kull mudell tal-ESD.

A complete ESD characterization of every new product prior to its release is highly recommended. Complete ESD characterization consists of subjecting the device to ESD testing for all of the three ESD models, i.e., HBM, CDM, MM. Data for one ESD model can not be substituted for those of the other ESD models, since good ESDS test results for one model doesn't necessarily mean that the test results will also be good for the other ESD models. Thus, a company that takes its ESD program seriously must equip itself with ESD tester(s) capable of performing the required ESD tests for each of the test models.
