2、HIELD WITH WSB-M15P36-A PRESSURE SENSITIVE ADHESIVE NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines the minimum performance requirements for an inner door watershield comprised of a base material with pressure sensitive adhesive applied on one side in specified areas. 2. APPLICATIO

3、N This specification was released originally for materials used on the 1991 Lincoln Town Car. 3. REQUIREMENTS 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford Quality System Standard Q-101. A mutually acceptable Control Plan as described therein is required for material/sou

4、rce approval. Appropriate statistical tools must be used to analyze process/product data so that variation in the final product is continuously reduced. 3.2 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on materials conditioned in a controlled atmosphere of 23 +/- 2 C a

5、nd 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. 3.3 BASE MATERIAL 3.3.1 Tear Strength, min 150 N/cm (ASTM D 1004) 3.3.2 Dimensional Stability, max 3 % (ASTM D 3575, 80 +/- 2 C) 3.3.3 Cold Flexibility No cracks T

6、est Method: Cut 25 x 150 mm strips in both directions. Condition the strips and a 13 mm diameter mandrel at - 34 +/- 2 C for 4 h. Bend the conditioned strips 180 deg around the mandrel within 2 - 3 s. ENGINEERING MATERIAL SPECIFICATION WSB-M15P36-A WP 3948-b Page 2 of 4 3.3.4 FLAMMABILITY (ISO 3795/

7、SAE J369) Burn Rate, max 50 mm/minute 3.3.5 FOGGING (FLTM BO 116-03) Fog Number, min 60 Formation of a clear film or droplets is cause for rejection. 3.4 BASE MATERIAL WITH ADHESIVE 3.4.1 Adhesion Strength, min (ASTM D 1000, 90 degree peel angle, 5 mm/s peel rate, moving plate) Original, 20 minutes

8、1.7 N/cm after application Original, 24 h after 2.4 N/cm application After 24 h water immersion 2.4 N/cm at 23 +/- 2 C Aged 24 h at 85 +/- 2 C 3.0 N/cm Aged 24 h at - 18 +/- 2 C 2.0 N/cm Sample preparation: Bond 25 x 200 mm samples of adhesive coated composite to 100 x 300 mm steel panels, painted w

9、ith the production paint system to be used, by passing over twice with a 2.0 kg roller. Condition bonded samples as noted above prior to testing. All tests are conducted at standard conditions of 23 +/- 2 C and 50 +/- 5 % relative humidity. 3.4.2 Hydrostatic Pressure Resistance No leakage (ASTM D 75

10、1, Method A, Procedure 1) Raise the pressure at a rate of 10 mm/s to a maximum of 500 mm pressure. Sample Preparation: Cut a 25 x 25 mm sample of adhesive coated composite and apply over the 12.5 mm diameter hole in the center of the primed steel panel cut to a size suitable for the test machine bei

11、ng used. ENGINEERING MATERIAL SPECIFICATION WSB-M15P36-A 3.4.3 Environmental Exposure After exposure, there shall be no evidence of delamination, puckering or gapping around the adhesive seal area. Any change which would cause water leakage constitutes failure. Test Method: Apply a production repres

12、entative part or a 450 x 750 mm sample with a 20 mm wide peripheral band of adhesive to a steel panel, painted with the production paint system to be used, using the suppliers recommended methods. Condition the bonded assembly for 24 h at 23 +/- 2 C and 50 +/- 5 % relative humidity. Expose the assem

13、bly to the following environmental cycle: . 24 h at 38 +/- 2 C and 95 +/- 5 % R.H. . 6 h at - 35 +/- 2 C . 12 h at 82 +/- 2 C . 6 h at - 35 +/- 2 C . 24 h at 38 +/- 2 C and 95 +/- 5 % R.H 3.5 ADDITIONAL REQUIREMENTS Specific requirements for material and/or manufactured parts shall be specified on t

14、he engineering drawing, Engineering parts specification and/or performance specifications. All critical areas with respect to these properties shall be clearly designated on the Engineering drawing. 3.6 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be equivalent in all c

15、haracteristics to the material upon which approval was originally granted. Prior to making any changes in the properties, composition, construction, color, processing or labeling of the material originally approved under this specification, whether or not such changes affect the materials ability to

16、 meet the specification requirements, the Supplier shall notify Purchasing, Toxicology and the affected Materials Engineering activity of the proposed changes and obtain the written approval of the Materials Engineering activity. Test data, test samples and a new code identification are to be submit

17、ted with the request. Substance restrictions imposed by law, regulations or Ford apply to the materials addressed by this document. The restrictions are defined in Engineering Material specification WSS-M99P9999-A1, unless a different suffix (e.g., A2 or A3) is specified on the engineering document

18、for the application. ENGINEERING MATERIAL SPECIFICATION WSB-M15P36-A WP 3948-b Page 4 of 4 4. APPROVAL OF MATERIALS Materials defined by this specification must have prior approval by the responsible Materials Engineering activity. Suppliers desiring approval of their materials shall first obtain an

19、 expression of interest from the affected Purchasing, Design and Materials Engineering activity. Upon request, the Supplier shall submit to the affected Materials Engineering activity its own laboratory report to the specification (test results, not nominal values), the material designation and code number and test specimens for Ford evaluation. Upon approval, the material will be added to the Engineering Material Approved Source List.
