The settled density of lose fill insulation must be determined before the corrosiveness test (§ 1209.5 ) and the smoldering combustion test (§ 1209.7 ) can be performed. This section describes the procedure for determining the settled density of loose fill insulation.
Settled Density in kg/m3 = W/Vs, where
W = combined weight of the container and insulation in grams, minus the weight of the container in grams.
Vs = volume of insulation in liters after shaking.
