Guide for choosing a Baloon Density Apparatus:
Max grain size (mm) Min hole volume (liters) Minimum moisture content per sample (grams)
4.75 0.700 100
12.50 1.400 250
25.00 2.100 500
50.00 2.800 1000
63.00 3.800 1500
The choice of aparratus is governed by the material to be tested.
The standard stipulates that when testing grain sizes smaller than 4.75 mm, a Baloon Density Apparatus with a volume of approximately 1600 ml should be selected. For grain sizes larger than 50 mm, one with a volume of 6000 ml or larger should be selected.
