EMC Test Plans, A Requirement for Proper Testing

EMC Test Plans

EMC Test Plans

EMC Test Plans are important in preparing for your trip to the lab.  The test plan should communicate all relevant information about the nature of the system to be tested.  This will allow the test lab to sufficiently assess the requirements needed to complete testing.  These requirements include: size of chamber, number of antennae positions, numbers of cables to be tested, power requirements, and specific measurement and susceptibility equipment.

Equipment Function

Representative functionality is a requirement in EMC testing for both commercial and military applications.  The EMC test plan should include a description of all modes of operation.  The plan should also provide a description of all peripheral equipment required to attain this functionality.  This information should also include a description of normal operation so that an assessment can be made in evaluation of susceptibility.


The lab will need to know if any potential hazards are posed by the equipment to be tested.  This will allow for any precautionary measures to be made ahead of time.  Because susceptibility testing can produce unforeseen equipment malfunctions, the EMC test plan should also include shut down procedures.


Every standard will have general requirements for EMC test plans.  These include: product identification, description, power requirements, cable requirements and descriptions.  Certain standards, like MIL-STD-461, have very detailed and specific additional requirements.   Understanding the testing to be performed and the applicable standards will therefore ensure that the data provided is complete.

Why Write a EMC Test Plan?

Preparing an EMC test plan provides the test lab with the data to properly assess compliance of your product.  It also provides the necessary information for the lab to create a viable EMC Report which is a necessary record of your product’s conformity to applicable requirements.
