11、ng substrates, paint, coatings, adhesion promoters and adhesives shall have been qualified and approved to the appropriate GM specifications. 3.1.6 All cure/activation schedules are to be those of the production system and must agree with the adhesive manufacturers recommendations. 3.1.7 Test Review

12、. When testing is completed, the tested components will be reviewed by the responsible GM Materials Engineer. 3.1.8 Test Conditions. Tests shall be conducted using the latest issue of the test methods indicated in Table A1. Suitable precautions should be taken to ensure that applicable safe limits a

13、re not exceeded when conducting test procedures, processes and/or handling the materials required by this specification. 3.2 Requirements on Test Specimens. Reference GMW3221. 3.2.1 Sample Conditioning. Unless otherwise specified, bonded samples shall be subjected to testing after a minimum aging pe
