Plastics - Determination of apparent density
of material that can be poured from a
specified funnel
(ISO 60:1977, IDT)
This Malaysian Standard specifies a method of determining the apparent density, i.e. the mass per unit of volume, of loose material (powder or granular material) that tan be poured from a funnel of specified design.
NOTE - For a method of determining the apparent density of loose moulding material that cannot be poured from a specified funnel.
When the method is applied to relatively coarse materials, rather variable results may be obtained, owing to the error introduced when a straightedge blade is drawn across the top of the cylinder.
A knowledge of apparent density is of limited value in estimating the relative fluffiness or bulk of moulding materials, unless their densities in the moulded condition are approximately the same.
