Component EMC Specifications EMC-CS-2009

This engineering specification addresses electromagnetic compatibility (EMC) requirements for electrical and/or electronic (E/E) components and subsystems for Ford Motor Company (FMC), which includes all of its associated vehicle brands.  These requirements have been developed to assure compliance with present and anticipated domestic and foreign regulations in addition to customer satisfaction regarding the EMC of vehicle E/E systems. 

EMC-CS-2009 replaces specification ES-XW7T-1A278-AC.  ES-XW7T-1A278-AC is no longer available for download on this website.  Requests for this specification should be forwarded to the appropriate design activity within Ford Motor Company.

Editorial updates to EMC-CS-2009 can be made at anytime and without prior notification to the user.  It is recommended that the user check this site to verify they have the latest copy of the specification.

EMC-CS-2009 contains several changes in both requirements and test method as compared to ES-XW7T-1A278-AC. Specific.  Click here for a summary of the differences between these two documents.  Two specific items worth noting are:

• Use of EMI receivers with Fast Fourier Transform (FFT) capability for performing radiated emissions measurements (i.e. RE 310, CE 420).  This allowance greatly reduces overall measurement time.  However, at this time this time the only EMI FFT receiver accepted by Ford Motor Company is the
  Rohde and Schwarz ESU.
• A new test fixture for performing RI 130 and RI 150.  The fixture facilitates improved testing regardless of the number of interface circuits of the product.  Click here for details with respect to construction of this device.  Note that all recognized EMC labs the construct their own fixture must perform parametric measurements to verify the fixture is constructed correctly.  Those measurements must be approved by Ford Motor Company.  Although not required by Ford Motor Company, the fixture may be purchased commercially from Rohde and Schwarz (part number RSA TS-RI130-Fix).  This fixture has already been validated by Ford Motor Company.  Currently there are no other commercial suppliers of this fixture.

Processes associated with the EMC-CS-2009 are found in a separate specification called EMC-P-2009.  Processes include Test Plan Creation Requirements, Data Reporting and Re-Validation requirements.  At this time EMC-P-2009 is not publicly available, but may be obtained by contacting the appropriate design activity within Ford Motor Company.
