15、erials according to these specifications shall meet all requirements of performance specifications WSS-M11P57-A5. 3. 6 LINE TRIAL The Requirements defined in this specification are based upon laboratory coupon testing and define the minimum acceptance criteria for adhesive performance. Prior to use,

16、 the adhesive must be evaluated under the production parameters of the relevant production line. The choice of substrates, plant processing conditions and specific design application may affect adhesive performance. Compliance with this specification does not guarantee the adhesive will function for

17、 all potential applications on a vehicle. Therefore materials being evaluated for approval to this specification shall be subjected to a production trial. Functional trial results must be approved by the affected assembly operation. Results shall be made available to Materials Engineering prior to m
