5. Perform testing at a FMC recognized test facility.
6. Submit the test results to the FMC EMC department. See section 5.7 for reporting requirements.
7. EMC department reviews and assesses the test results.
It’s important to emphasize that the FMC D&R group and their supplier (not the FMC EMC department) are responsible for
determining the operating modes and acceptance criteria for their component or subsystem (step 3). The FMC D&R group is
also responsible for verifying that the requirements delineated in this specification are met. The supplier is responsible for
performing the verification testing in accordance with the requirements of this specification.
The FMC EMC department reserves the right to perform audit testing or witness supplier design verification (DV) on sample
parts in order to verify compliance with this specification. Compliance to these EMC requirements shall be determined
by the FMC EMC department after review of the test results submitted by the test laboratory. The supplier may not
self certify compliance to these specifications. See section 5.7 for additional detail concerning this requirement.
1.4 Additional Information
E/E component or subsystem testing to the requirements of this specification represents an empirical risk analysis of
component/subsystem performance versus derived approximations to known environmental threats and customer satisfaction
requirements. The development of this specification is based on extensive experience in achieving correlation to expected
vehicle performance with a high level of predictability. However, EMC testing, by its nature, is subject to similar variation
as mechanical testing. Because of coupling variability and measurement uncertainty, correlation between
component/subsystem level performance and final performance in the complete vehicle cannot be exact. In order to maintain
a competitive and quality product, vehicle EMC testing will be performed to evaluate overall integrated system performance.
However, vehicle level analysis and testing is not a substitute for component/subsystem conformance to this specification.
This specification does not include any information regarding component/subsystem design required to meet the
requirements presented herein. Information on this subject may be found in ES-3U5T-1B257-AA “EMC Design Guide for
Printed Circuit Boards”, which is available for download from http://www.fordemc.com
. Additional information may be
found from a number of technical journals and textbooks.
Requirements contained herein that pertain to conducted emissions or immunity are limited to low voltage DC applications
(e.g. 12 VDC). Conducted requirements pertaining to high voltage systems (e.g. HEV, PHEV, EV) are not covered in this
specification. However high voltage systems must comply with other EMC requirements (e.g. RF emissions/immunity, ESD
requirements) as delineated herein. See Table 6-1 for specific applicability.
Although every attempt has been made to assure the information contained herein is accurate, editorial updates and/or
technical clarifications to requirement/test methods are made when noted. This information may be found at
http://www.fordemc.com
. The user (i.e. suppliers, test laboratories) shall review this information prior to preparation of
component EMC test plans and/or execution of testing.
