Test method: Plates of approximately 20*20cm2 are heated in an oven with recirculated air and then doused in the center with 50ml of room temperature water,at which5%of the samples suffer breakage. The plates are abraded before heating with 220 grit sandpa-per to simulate typical surface condition during practical use .
