Compliance Mark Definitions

Equipment sold to the commercial avionics industry worldwide must be tested for compliance to the Radio Technical Commission for Aeronautics DO-160 (RTCA DO-160) EMI/EMC specifications. Additionally, testing for shock, vibration and environmental testing must be accomplished on the equipment before delivery to the procuring agency.

Testing for compliance to EMI / EMC specifications is done in a laboratory environment. A test plan is written for the EMC testing prior to initiation of qualification testing. The test plan is approved by the procuring agency prior to the equipment going into testing.

Emissions testing - both magnetic and electric field radiated fields - as well as conducted emissions are measured from the equipment when it is in a typical end-user configuration. Various conducted susceptibility tests are performed on the equipment that are dictated by its environment of use. Numerous radiated susceptibility tests are also a part of the compliance testing for the avionics; again, the susceptibility voltage density is set by the equipment's environment of use.

Upon successful completion of testing, a formal engineering report will be submitted to the procuring agency.
