1.1 ,This test method covers the determination of the apparent viscosity of petroleum waxes compounded with additives (hot melts). It applies to fluid hot melts having apparent viscosities up to about 20 ,Pa·,s at temperatures up to 175 ,°,C (347 ,°,F).
Note 1: ,For petroleum waxes and their blends having low apparent viscosities, below about 15 ,mPa·,s, Test Method D445, is especially applicable.
