SCOPE The material

2、defined by this specification is a flexible polyurethane foam offering a degree of water impermeability for various sealing applications. The finished part shall be furnished with a pressure sensitive adhesive and that adhesive shall be protected with a suitable release paper. The pressure sensitive

3、 adhesive is intended as an assembly aid and should only be used when the seal is mechanically retained in the final assembly. 2. APPLICATION This specification was released originally for material used as gasketing for heater and air conditioning units. 2.1 LIMITATIONS The pressure sensitive adhesi

4、ve is intended as an assembly aid and should only be used when the seal is mechanically retained in the final assembly. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when th

5、is specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer.

9、mple Preparation: For adhesive peel strength testing a standard test panel made of filled polyester shall be used. Adhere at least 5 in (125 mm) of the adhesive backed foam to the panel using a rubber covered steel roller. The roller shall be 3.25 +/- 0.1 inches (82.6 +/- 2.5 mm) in diameter and 1.7

10、5 +/- 0.05 inches (44.5 +/- 1.3 mm) in width, covered with rubber approximately 1/4 inch (6.4 mm) in thickness having a durometer hardness of 80 +/- 5. The weight of the roller which applies pressure to the foam specimen shall be 4.5 +/- 0.1 lb (2.04 +/- 0.05 kg). The roller should be constructed so

11、 that the weight of the handle is not added to the weight of the roller during use. Pass the roller without applying additional pressure over the gasket lengthwise, once in each direction at the rate of approximately 2 in (50 mm)/s. Allow 20 min before “as received“ testing. Apply masking tape to th

12、e surface of the foam to reduce the friction between the foam surfaces when the specimens are bent 180 in respect to each other. 3.13 RELEASE FILM SEPARATION (ASTM D903) Tested at room temperature, the release paper film shall separate from the adhesive at a maximum initial peel value of 0.109 N/mm

13、of width and the continuous peel value shall not exceed 0.055 N/mm of width. 3.14 ADHESIVE PEEL STRENGTH, DEAD LOAD TEST No Separation (ASTM D3654) Test Method Options: 3.1 Procedure A, Shear Adhesion to Standard Steel Panel; 3.9 A specimen size of 24 by 24 mm., 5.5.4.1 The test mass shall be 500 +/

GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requ

15、irements of this specification. Contact for questions concerning Engineering Material Specifications. 4.1 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Product Development, and Materials Engineering. The

16、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 the Material Specification. Tested material samples must be available for review upon request

17、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. 4.2 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristic

18、s 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 specification requirements, the supplier shall notify the affected Supplier Technical Assistance (STA),

19、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 Engineering Material Specifications, all samples tested to the specifications for Design Verifica

20、tion (DV), Production Verification (PV) and Production Part Approval Process (PPAP) sign off must be kept until Job 1. 4.3 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by regulations 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
