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[dot]s at temperatures up to 175°C (347°F).

1.2 The values stated in SI units shall be regarded as the standard. One pascal second (Pa[dot]s) = 1000 centipoises (cP). One millipascal second (mPa[dot]s) = 1 centipoise (cgs units).

Note 1-For petroleum waxes and their blends having low apparent viscosities, below about 15 mPa[dot]s, Test Method D445, is especially applicable.
