scope:

1.1 These test methods cover determination of the bond integrity of transparent laminates. The laminates are usually made of two or more glass or hard plastic sheets held together by an elastomeric material. These test methods are intended to provide a means of determining the strength of the bond between the glass or plastic and the elastomeric interlayer under various mechanical or thermal loading conditions.

1.2 The test methods appear as follows:

Test Methods	Sections
Test Method A-Flatwise Bond Tensile Strength	5 - 11
Test Method B-Interlaminar Shear Strength	12 - 17
Test Method C-Creep Rupture	18 - 25
Test Method D-Thermal Exposure	26 - 30
