1.1 ,This test method covers the determination of the apparent viscosity of hot melt adhesives and coating materials compounded with additives and having apparent viscosities up to 200 ,000 millipascal second (mPa·,s) (Note 3) at temperatures up to 175 ,°,C (347 ,°,F).
Note 1: ,Although precision has not been studied, this procedure may be adaptable to viscosities higher than the present 200 ,000 ,mPa·,s limit and temperatures above 175 ,°,C (347 ,°,F). Equipment described in this test method permits testing of materials having viscosities as high as 16 ,×, ,106 mPa·,s and provides temperatures up to 260 ,°,C (500 ,°,F).
