I
INTRODUCTION
This document has been developed jointly by personnel from DaimlerChrysler (DC, Chrysler Group),
Ford Motor Company (Ford), and General Motors Corporation (GM). The intent of the participants has
been to establish common criteria for the evaluation of the competency of automotive EMC laboratories
by third party accreditation bodies.
This document defines the requirements of the Automotive EMC Laboratory Recognition Program and
serves to:
a) provide supplier and third party laboratories with the specific requirements they will be evaluated
against, and
b) provide accreditation agencies with specific requirements to be used in evaluating laboratories.
The Scope of Accreditation must include a list of the specific automotive EMC tests from this document
for which accreditation has been granted.
NOTE: IT MUST BE UNDERSTOOD THAT ACCREDITATION IS THE ACKNOWLEDGEMENT THAT A
LABORATORY HAS BEEN ABLE TO DEMONSTRATE THAT IT HAS THE COMPETENCY TO
CONDUCT THE TESTS INCLUDED IN SCOPE OF ACCREDITATION AT THE TIME OF
ASSESSMENT. IT IS NOT A GUARANTEE OF THE ACCURACY OF DATA SUPPLIED BY THE TEST
LAB TO THE PURCHASER.
It is the intent that the accreditation process will be available to suppliers and third party laboratories,
regardless of where they are located. At this point, we have established AGREEMENTS with A2LA
(American Association for Laboratory Accreditation) in North America, EA (European Cooperation for
Laboratory Accreditation) in Europe, and JAB (Japan Accreditation Board for Conformity Assessment) in
Japan.
The cost of having a laboratory accredited is to be funded by the laboratory and is to be paid directly to
the accrediting body.
It is intended that a list of accredited Automotive EMC Laboratories be maintained on the Internet and will
be accessible to any interested party. This listing would most likely include the tests in the scope of
accreditation and the date of the accreditation. For lab approval status, visit www.sae.org for GM and
www.fordemc.com for Ford. Contact DC to obtain the information for the DC suppliers.
The organizers of this program realize that for the assessors to perform their duties competently and
fairly, training of assessors will be required initially and on an ongoing basis. The organizers are
committed to supporting this activity.
There is an on-going effort to harmonize automotive EMC test procedures. This document will be
updated on a regular basis to reflect changes resulting from this harmonization effort and changes in the
reference test method documents. There is an Addendum to the AEMCLRP Requirements document
also available at www.sae.org that contains interim changes for this document.
Visit the SAE website and follow the links: www.sae.org -- Committees and Forums – Automotive –
Automotive OEM EMC Committee – Automotive EMC Laboratory Recognition Program
Procedures are based on ISO, CISPR, SAE, and company specific procedures.
Each company using this program as part of their purchasing requirements will do so independently.

Automotive EMC Lab Recognition Program
DaimlerChrysler Implementation
DaimlerChrysler supplier EMC laboratory approval policy: All component EMC test data submitted to DC
is required to be from an EMC lab approved by DC. An approved EMC laboratory is a lab that meets the
requirements for acceptance by Mercedes Car Group and Chrysler Group through accreditation to ISO-
17025. The basic test methods as defined in the international standards that are referenced in this
standard, e.g. ISO 10605, ISO 11452-2 and CISPR 25, shall be within the scope of the accreditation.
This accreditation shall be performed by a nationally recognized accrediting body operating in
accordance with ISO/IEC 17011. DC reserves the right to arrange for follow-up correlation tests and/or
on site visits to evaluate the DC test methods not included in the ISO-17025 requirements and to further
review and discuss the tests defined in the DC EMC Specifications. A laboratory which refuses such
follow-up activities or for which significant discrepancies are found is subject to having its
approval/recognition withdrawn.
DaimlerChrysler (Chrysler Group only) requires its supplier EMC laboratories to submit a Self-
Assessment Form to update lab accreditation results and testing capabilities for all tests outlined in the
DaimlerChrysler Specification with detailed requirements contained in the Self-Assessment Form. The
copies of accreditation evidence and required documents shall be provided along with the Self-
Assessment Form. The information will be posted on the Chrysler intranet website to provide the
reference for DC product teams.
DaimlerChrysler (Chrysler Group only) reserves the right to select limited number of 3
rd
party laboratories
to meet the suppliers’ needs in order to reduce the burden on maintaining 3
rd
party laboratories.
Ford Motor Company Implementation
Recognition of test methods not included in the AEMCLRP requires submittal of a test facility report,
which serves to demonstrate the laboratories capability to perform those tests. Details on the test facility
report in addition to information on Ford Motor Company's participation in the AEMCLRP may be found at
http://www.fordemc.com (click on the Laboratory Recognition Program link). Ford Motor Company
reserves the right to arrange for follow-up correlation tests and on site visits to review laboratory
procedures and test methods defined in the Ford EMC Specification. A laboratory which refuses such
follow-up activities or for which significant discrepancies are found is subject to having its recognition
withdrawn.
Ford test plan template can be obtained by accessing www.fordemc.com. Click on the ‘Downloadable
documents’ link.
General Motors Implementation
General Motors reserves the right to arrange for follow-up correlation tests and on site visits to evaluate
the GM test methods not included in the AEMCLRP requirements and to further review and discuss the
tests defined in the GM EMC Specification. A laboratory which refuses such follow-up activities or for
which significant discrepancies are found is subject to having its recognition withdrawn. Other details on
GM implementation can be found in the GMW EMC specification. For tests that are not included in the
AEMCLRP requirements, it is recommended (but not required) that the laboratory add these tests to its
scope of accreditation under the generic international document (for example, ISO 7637-2 for Conducted
Transient Immunity).
GM documentation, including the test plan template (GMW3103), can be obtained by purchasing from
Global Engineering Documents: global.ihs.com.

CRITERIA FOR AUTOMOTIVE EMC LABORATORY ACCREDITATION
ISO/IEC 17025 and the proficiency tests defined in this document are the basis for determining the
competency of laboratories in this program.
An EMC laboratory that applies for AEMCLRP accreditation needs to be accredited to ISO 17025 as a
prerequisite. This accreditation shall be performed by any nationally recognized accrediting body (or
bodies) operating in accordance with ISO/IEC 17011. The methods selected from Table 1 shall be also
in the scope of the accreditation to ISO 17025.
NOTE: The combination of ISO 17025 accreditation plus AEMCLRP accreditation in one assessment is
allowed.
Application of ISO/IEC 17025
This section provides clarification and additional specific requirements applicable to the “Automotive
EMC” laboratory accreditation. Each of the reference numbers below relates to the corresponding
section of ISO/IEC 17025.

1.1
2.0
Scope
These requirements are for EMC laboratories interested in becoming accredited and
recognized to conduct automotive specific EMC test procedures.

Terms and Definitions
Additional definitions are provided in Appendix B.
4.5
