Immunity testing sets out to prove that a device has an adequate level of intrinsic immunity to electromagnetic disturbance to enable it to operate as intended.  In general terms, the product must function normally while being subjected to various electrical phenomenon.  Most immunity testing requires very specialized and expensive equipment as well as controlled  test environments.  Expertise in test standards, familiarity with test protocol, suitable equipment and calibration are all key elements to a valid immunity test.  You will find all of these elements expertly covered at PSE.

An experienced test engineer will work closely with the client to find a way to exercise the product and monitor its functionality during testing.  Often times the engineer may utilize specifications called out in the product's manual or marketing literature as a basis for normal operation, as would be expected by the end user.  When a product fails to meet the level of immunity called out by the applicable test standard, the client often relies on the test engineer for guidance as to how the issue may be resolved.  Many manufacturers have very little experience with immunity testing since it is not mandatory compliance for IT equipment in any market other than Europe.  For this reason, selecting a test lab with extensive expertise and state-of-the-art equipment is imperative to a successful test plan.

Product Safety Engineering went through a half million dollar expansion in 1995 in order to become proficient and capable in the immunity test arena.  Since then, our staff has assisted countless manufacturers in overcoming obstacles and successfully meeting the immunity requirements of the EMC Directive for CE marking.  Contact us today for more information about how PSE can help you.
