2、c. LEATHER, FOAM LAMINATE, SEATING QUALITY WSB-M8P17-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a genuine leather laminate, consisting of seating quality leather adhesively bonded to urethane foam. 2. APPLICATION This specification was released originally

3、for materials used as bonded leather seat cushions and seat backs. The bonding operation eliminates tack sewing of the leather to foam prior to assembly of the seat cover. Materials and suppliers meeting this performance specification are identified on the Corporate Approved Source List. 3. REQUIREM

4、ENTS Material specification requirements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to the Companys Quality System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermo

5、grams established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.3 CONDITIONING AND T

6、EST CONDITIONS All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified.

The materials used in this laminate must

8、exhibit fogging results equivalent to or better than the approved production materials. 3.5 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved master sample, or shall be as specified on the engineering drawing. 3.6 MATERIAL ACCEPTABILITY The criterion for material ac

9、ceptability shall be the assemblys job performance. This means that the materials composition and formulation must lend itself to satisfactory fabrication under approved production conditions. 3.7 CONSTRUCTION Leather As specified on engineering drawing. Foam or Foam Laminate As specified on enginee

10、ring drawing Adhesive Must use WSB-M2G57-C adhesive or as specified on the approved source list. Sheeting As specified on engineering drawing. Materials and suppliers meeting this performance specification are identified on the Corporate Approved Source List. 3.8 PLY ADHESION, both directions, min (

Test Method: Apply adhesive to the lea

12、ther/foam samples using production equivalent techniques. Test a minimum of five specimens in each direction. Test specimens with applied adhesive shall be conditioned for 24 h at 23 +/- 2 C and 50 % relative humidity prior to exposure. Ply adhesion tests shall be completed within 4 h after removal

13、from the exposure environment unless otherwise noted. The ply adhesion values obtained on each test specimen must exceed the following requirements. Leather to Foam Foam to Sheeting Original 4.4 N* 3.5 N Heat Aged 7 days 4.4 N* 3.5 N at 100 +/- 2 C Humidity 7 days at 3.5 N* 3.5 N 38 +/- 2 C and 95 %

14、 +/- 5 % relative humidity Adhesion between the leather and foam must be sufficient to withstand handling, shipping and sewing operations without delamination or loss of registration. *The leather shall not separate cleanly from the foam surface, and the peeled leather specimen shall exhibit foam pa

15、rticles adhering to the peeled surface area. 3.9 COMPATIBILITY The foam/adhesive/leather combination shall be compatible. Bonded areas shall exhibit no staining or color change greater than that observed in unbonded areas after exposure to the following conditions: 3.9.1 Heat Aging 7 days at 100 +/-

16、 2 C In addition, the leather must remain flexible and not crack when bent around a 6.4 mm mandrel. 3.9.2 Fade 225.6 kJ (SAE J1885) ENGINEERING MATERIAL SPECIFICATION WSB-M8P17-A Page 4 of 4 Copyright 2015, Ford Global Technologies, Inc. 3.10 COLD FLEX (FLTM BN 102-01) Shall remain flexible and not

18、 System Design Specification (SDS) and/or Component Design Specification (CDS). 3.13 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material

19、 originally approved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall notify the affected Purchasing, and Materials Engineering activities (with reasons) of the proposed changes. Upon notification of the Com

20、pany, further instructions will be provided. Note: Suppliers should be prepared to provide test data and samples demonstrating compliance to this specification, if requested. Substance restrictions imposed by regulations or Company direction applies to the materials addressed by this document. The r

21、estrictions are identified in Restricted Substance Management Standard WSS-M99P9999-A1. 4. APPROVAL OF MATERIALS Materials defined by this specification for direct supply to the Company must have prior approval. Certain materials subcontracted by part suppliers may also require prior approval. These

22、 include materials critical to the Companys business for regulatory, safety, environmental or compatibility requirements or contractual agreements. Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Materials Engineering activity. Upon request, 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 this specification.
