The purpose of Immunity Testing is identification
of product vulnerability to various types of "real world"
electromagnetic phenomena. The types of electromagnetic interference
simulated are those to which a product will likely be exposed in normal
usage.
Most products destined for the European
market usually bear the CE mark. Application of the CE mark signifies
compliance with all applicable European "Directives." Immunity testing
is required to demonstrate compliance with the essential requirements
of the "EMC" Directive 89/336/EEC. Article 4(b) of this directive
states; "The apparatus shall be so constructed that" it has "an
adequate level of intrinsic Immunity of electromagnetic disturbance to
enable it to operate as intended." Although neither the FCC nor
Industry Canada require Immunity testing, there are nevertheless
benefits to be gained from product-designs that are immune to
electromagnetic interference: Improved product reliability and greater
customer satisfaction.
