Page 3 of 6 Determine shear strength using 25 mm/minute test speed. Test a minimum of 5 specimens for each exposure. The average result shall conform to the speci
14、fied requirement. Note: If the laminated glass fails before reaching the minimum shear strength requirement, the test is to be rated as satisfactory and the result noted in the report, provided that no adhesion failure occurred. 3.4.2.1 Original Measured at 90 +/- 2 C *, min 1.5 MPa Measured at 23 +
15、/- 2 C Measured at - 40 +/- 1 C * * 30 minutes tempering time until measuring. 3.4.2.2 Heat Aging 14 d at 90 +/- 2 C, 1 h at 23 +/- 2 C 3.4.2.3 Florida Exposure Test Method: Specimens prepared according to 3.4.2 shall be cured for 24 h min and then exposed in the Miami Florida area for 1 year with t
16、he glass facing the light at 5 south. The glass shall be cleaned with distilled water once a month. 3.4.2.4 UV-Exposure Test Method: Allow the adhesive to cure for 24 h before weathering. Expose test assemblies with glass facing the light source per SAE J1960 at a) 1570 kJ/m2 and b) 3920 kJ/m2 Deter
