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.
