Laboratory Recognition (updated 7/6/2015)

 

All formal design and production validation EMC testing of automotive products for Ford Motor Company (FMC) is performed only by EMC testing laboratories recognized by FMC.  Prior to September 2011, the process used for laboratory recognition was the Automotive EMC Laboratory Recognition Program (AEMCLRP).  However, FMC, along with Chrysler and General Motors (i.e. the OEMs) have collectively agreed to officially terminate AEMCLRP and replace it with a similar "OEM recognition process".  It must be noted that while the OEMs will strive to keep their processes as similar as possible, laboratory recognition will be executed by each OEM independently and will therefore vary somewhat due to differences in OEM specific test methods and other factors.

The information presented describes the process that will be used by FMC.  Questions and/or comments concerning these changes shall be forwarded the individuals, listed below, who are responsible for laboratories within their geographical region:

Keith Frazier (kfrazie1@ford.com)

North/South America, Japan

Peng Peng (ppeng1@ford.com)

China, SE Asia

Ayhan Gunsaya (agunsaya@ford.com)

Europe

Rodney Huebner (rhuebner@ford.com)

Australia, India

 The process for new laboratory recognition is shown in Table 1.  For reference a comparison of the AEMCLRP to the FMC laboratory recognition process corresponding to the AEMCLRP / ISO 17025 sections is summarized in Table 2.

It is neither necessary nor recommended for the lab to gain accreditation to FMC specific test methods.  Accreditation to FMC test methods will not facilitate recognition by FMC.  Accreditation is granted by an, ILAC MRA signatory assessment body but recognition comes from the FMC.

Existing recognized EMC laboratories are maintain their accreditation to ISO 17025 inclusive of the relevant international standards (see Step 3, Table 1).  Additional information may be required from the laboratory upon request from FMC.  For example, if FMC test requirements change, issues are reported, or lab test setup conditions dramatically change (i.e. new equipment).

FMC reserves the right to suspend the recognition of any laboratory that does not follow the requirements delineated herein in addition to any FMC documented conditions of recognition, specifications and/or processes (e.g. data reporting).  FMC may also elect to terminate recognition of laboratories that are not actively engaged in EMC testing of their related products.


Table 1 Process for Recognition (New Laboratories)

Step 1: Request for Consideration of Recognition

The lab shall contact FMC to request consideration for support of recognition.  The request must include a brief self-assessment of the laboratory capabilities to perform testing to Ford requirements, including a listing of any limitations.  The self-assessment shall include a list of equipment available to perform each test method.  Steps 2-6 cannot be completed until support of recognition is granted in writing by FMC.  Requests shall be forwarded to the contacts listed above that are responsible laboratory recognition within their geographical region.

Step 2: On-site Laboratory Visits

The need for an on-site visit will be determined based on the laboratory's self assessment

Step 3:  ISO 17025 Accreditation

The laboratory contacts any ILAC MRA Signatory Accreditation Body to arrange for accreditation to ISO 17025 along with accreditation to one or more of the base international standards specified in the Table 1. Recognition by FMC for a specific test method will require accreditation to the relevant base standard (e.g. the base standard for RI 112 is ISO 11452-4).  The accreditation certificate and a copy of the scope of accreditation showing the base standards included in the accreditation must be provided by the accreditation body in English.  It is preferred that this information be available as a link from the accreditation body’s website.

Step 4:  Prerequisite Information

An EMC test facility report shall be provided which includes, but not limited to, an updated copy of the self-assessment, test limitations, equipment lists, lab procedures, setup diagrams / test setup photos, performance history plan / data, and an example test report.

Step 5:  Performance History

Upon request by FMC, the lab shall provide evidence that they are executing a periodic verification of the stability in their test/measurement system for each test method.  This verification procedure must also be clearly defined in the facility report and approved by FMC.

Step 6:  Proficiency Testing

The lab may be requested to perform testing at their expense using an artifact provided by FMC or using an artifact owned by the laboratory if approved by FMC.  The test results are reviewed and approved by FMC.

AEMCLRP Requirement  Description

Implementation of the Requirement for
the FMC EMC Recognition Process

Section I

Introduction

Laboratories were accredited to ISO 17025 including evaluation and accreditation to specific OEM requirements.  Scope of accreditation included those OEM specific test methods

Laboratories shall be accredited to ISO 17025 but evaluation and accreditation is limited to base international standards (see Step 3, Table 1).  Only base international standards need to be part of laboratories Scope of Accreditation.

 

Assessment was only to be performed by accreditation bodies with established agreements with the OEMs.  Assessment performed only be OEM trained Assessors.

Assessment may be performed by any accreditation body that is an ILAC MRA signatory.  Assessment performed by assessors selected by accreditation body.

Section II

4.5.1 Calibration Laboratories

Calibration labs required ISO 17025 accreditation

Same requirement.

5.2

Personnel


Specific requirements delineated for lab supervisor.  Changes in personnel as defined in AEMCLRP were communicated to the AEMCLRP committee within 10 business days.  Concurrence required for laboratory to maintain recognition
 

Same requirements except changes in personnel shall be communicated directly to FMC.

5.4.1

General

Laboratory responded to a specific set of questions for each test method as listed in the AEMCLRP document.

Questions for the test method(s) delineated in base international standard will be determined by the assessor representing the ILAC signatory accreditation body.

5.4.1

Pre-assessment

Prerequisite information defined in appendix C of AEMCLRP document.

Pre-requisite information initially based on self assessment and in the facility report sent directly to FMC.  Additional prerequisite information required for accreditation to ISO17025 and base international standard will be determined by the ILAC signatory accreditation body.

5.4.1 Proficiency Testing

Proficiency testing was performed with OEM provided artifacts on an assessment cycle defined in Table 2 of AEMCLRP.

Proficiency testing shall be performed at the specific direction of FMC.  The artifacts may be provided by FMC or with an FMC approved artifact owned by the laboratory may be utilized.  The laboratory shall use their owned artifacts to provide evidence of repeatability and performance history.

5.4.1 Withdrawal of Recognition
