SCOPE These specifications define the performance and corrosion resista

3、nce requirements for various hexavalent chromium free alloy platings. 2. APPLICATIONS These specifications were originally released to define the performance requirements for zinc and zinc alloy plating. All platings are by electro-deposition, except where noted by an asterisk (*) for mechanical pla

4、ting. Topcoat finishes are acceptable to achieve corrosion resistant properties. Showroom Visibility: All high visibility vehicle components and fasteners shall be free of corrosion at the time of customer delivery. Moderate Visibility: All Other components, fasteners and subsystems (including brake

5、 system components visible behind wheel openings and engine compartment) shall be “corrosion-free“ for 4 YIS with wheels on ground, in the maximum turn position and all closures open. Underbody components and fasteners shall have no noticeable amounts of red rust when viewed from the rear of the veh

6、icle, at a distance of approximately two car lengths away for 4 YIS. High Visibility: Body system and other exterior components and fasteners, including aluminum and/or decorative steel wheels shall be free of red rust or conspicuous corrosion types for 5 YIS. These areas include all Class 1 and hig

7、h visibility exterior surfaces. The vehicle shall be evaluated with the wheels on ground and all closures open, except hood. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Mate

8、rials (WSS-M99P1111-A). 3.2 Corrosion Resistance Preconditioning For applications that require thermal, stone chip or weathering resistance, corrosion testing is to be performed on these components after the specified preconditioning exposure. 3.2.1 Thermal Resistance Heat component to 250 C, 180 mi

9、nutes, water quench (2 C +/- 5.0%).

11、18) Grade 6 or better) After completing the specified corrosion cycles, components plated to these specifications must meet the Corporate Standard for corrosion resistance. For approvals, corrosion testing to include Laboratory plus Total Vehicle Testing. Platings listed on the ASL have met or excee

APPROVAL PROCESS The information given below is provided for cl

14、arification and assistance in meeting the requirements of these specifications. 4.1 SUBSTRATE Test panels are to be used for initial qualification and must be plated and coated in the same production intent process. Perform testing on the following: o ACT Cold Rolled Steel Panels, Clean/Unpolished,

15、4 x 6 x 0.026 inch o Cast Gray Iron Panels (ASTM A 159, G3000), Clean/Blasted/Trimmed, 4 x 6 x 0.20 inch o Fastener testing shall be performed using M10 Hex Flange Bolts (W500034), Nuts (W520103) and Electrocoat Prime Painted Panels (PPG Powercron 590).

(ACT): ACT P.O. Box 735 or Hillsdale, MI 49242 4.2 NEW PRODUCT APPROVALS The addition of new products t

17、o the Engineering Material Approved Source List will be granted for specific combinations of zinc and zinc alloy plating, conversion coatings and sealers from a given chemical supplier. The system proposed for approval must be available globally. Finishes available only in a single region of the wor

18、ld will not be considered for approval. Chemical suppliers are expected to work on an ongoing basis with the metal finishers who use their products properly to meet Ford performance requirements. This will take the form of formal licensing or approval with ongoing periodic audits of licensed/approve

19、d finishing facilities. Chemical suppliers wishing to have their products added to the Engineering Material Approved Source List must first partner with a current Tier 1 supplier to Ford Motor Company and jointly present a valid business case (i.e. the total cost to Ford will decrease). After Ford h

20、as accepted the business case, the chemical supplier will provide the following test results to Ford: Compliance with Ford Engineering Material Specification Section 3 Requirements o Test 2 production batches, 3 pieces per batch chemical composition, plating and topcoat thickness. o The chemical com

21、position, thickness and topcoat data for the platings qualified are listed in the Approved Source List (ASL). Section 3.2.1 Corrosion Lab Test (FLTM BI 123-01): o Test 2 production batches, 3 pieces per batch. o For levels that require thermal, stone and weathering resistance, subject components to

22、these tests prior to performing the corrosion lab test. This testing is to be performed at a third-party laboratory. Process Flow Charts, Control Plans, Process FMEAs o Present copies of all relevant process control documents. Ongoing Application Control o Present plan for accessing finishers on an

23、ongoing basis, including evaluation criteria and frequency of evaluation. List of Approved Metal Finishers o Present list of metal finishers that have fulfilled the requirements of the licensing/approval program. o List must provide finishers located in at very least two of the major geographic regions (Asia/Pacific, Europe, North America, South America). o If the finish is not available in all regions, a plan to add licensed/approved finishers in the remaining regions must also be presented.
