Pummel adhesion of laminated glass is a method used to measure the relative adhesive bond strength between the interlayer and glass substrate interface. The interlayer to substrate adhesion has a great effect on the impact resistance of laminates as well as long term stability. This test method is intended to provide three levels of grading. This test method is not intended to provide more precision. The laminate bond strength, in most applications, must be controlled to avoid potential problems of delamination at low adhesion and impact failures or undesirable post breakage characteristics at high adhesion.
