1、 ENGINEERING MATERIAL SPECIFICATION Date Action Revisions Rev.0 2017 03 20 Released D. Murtonen, NA Controlled document at www.MATS Copyright 2017, Ford Global Technologies, LLC Page 1 of 4 LEATHER, GENUINE, PREMIUM, CHROME WSS-M1F28-D1 REDUCED EMISSIONS 1. SCOPE The materials defined by this specif
2、ication are steer or heifer hides which have been tanned and processed with full grain and no alteration to the top surface which allows a soft haptic without sacrificing the leathers physical properties. Top coat has a finish that allows for a standard haptic which is an attribute for this leather.
3、 Top coat finish is engineered to meet high abrasion characteristics. 2. APPLICATION These specifications were released for material used as seating leather. 2.1 LIMITATION This specification cannot be used for instrument panel covers, steering wheels or door uppers. 3. REQUIREMENTS 3.1 APPROVED SOU
4、RCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally
5、 through a Ford Materials Engineer. 3.2 SUPPLIER RESPONSIBILITY It is the Leather suppliers responsibility to inform the JIT supplier that subjecting leather to steam or radiant heat or organic solvents during any manufacturing process will adversely affect the hand and appearance characteristics. 3
6、.3 APPEARANCE The color, grain, gloss and hand shall match the approved Corporate Design master sample. 3.4 LEATHER PERFORMANCE Materials manufactured to this Specification shall also meet the requirements contained in WSS-M99P43-D/latest. 3.5 VEHICLE INTERIOR ENVIRONMENTAL PERFORMANCE Materials use
7、d in interior applications must meet the requirements outlined in WSS-M99P2222-D1/latest, Performance, Vehicle Interior Environmental Quality Material/Component Requirements. Data must be included in material submission package. 3.6 CONDITIONING AND TEST CONDITIONS ENGINEERING MATERIAL SPECIFICATION
8、 WSS-M1F28-D1 Copyright 2017, Ford Global Technologies, LLC Page 2 of 3 All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning enviro
9、nment or soon after removal. 3.7 SAMPLE SELECTION LOCATIONS The location of the test samples is described in ISO 2418 or ASTM D2813 for physical testing of leather samples. Refer to WSS-M99P43-D/latest for samples to be taken from the belly and backbone areas as noted in Table 1 of that specificatio
10、n. 3.8 FINISH All hides shall show no paint defects or surface blemishes affecting the appearance of the material, such as brush marks or stops. 3.9 THICKNESS 1.0 - 1.5mm (ASTM D 1813) or as specified on the Engineering Drawing 3.10 SHRINKAGE 5.0% max (FLTM BN 105-03, except Heat Cycle 100 +/-2 C, 3
11、 cycles) 3.11 STIFFNESS 60 +/- 10mm (FLTM BN 157-02) Stiffness measurements shall be taken along either side of the backbone. Stiffness must be tested from a hide. Stiffness cannot be taken from a pre or post assembled trim cover. Embossed or laminated leather will impact stiffness therefore, numeri
12、cal results could occur outside of the range above. Stiffness numerical values will not reflect a direct correlation to the haptic properties of leather. 3.13 STRETCH AND SET (SAE J855) Stretch 25% max Set 10% max 3.14 VOC EMISSIONS FROM VEHICLE INTERIOR MATERIALS (FLTM BZ 108-01) 3.14.1 Acetaldehyd

16、 of interest from Purchasing, Design or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of th
17、e Material Specification. Tested material samples must be available for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford.
18、 4.3 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specificatio
19、n requirements, the supplier shall notify the affected Supplier Technical Assistance (STA), Purchasing, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA. For parts and components using Ford Engin
20、eering Material Specifications, all samples tested to the specifications for Design Verification (DV), Production Verification (PV) and Production Part Approval Process (PPAP) sign off must be kept until Job 1. 4.4 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by regulation
21、s or Company direction applies to the materials addressed by this document. The restrictions are identified in the Restricted Substance Management Standard WSS-M99P9999-A1 which is updated yearly. It is the suppliers responsibility to comply with this standard on a continuing basis through IMDS and or GMAP reporting. 5. SUMMARY OF REVISIONS
