2. Fill the weight plunger with lead shot to obtain a total weight of 2300 ± 20 g (5.07 ± 0.04 lb), including the plunger. Lower this weight gradually into the measuring cylinder until it is entirely supported by the material. Allow the weight to settle for 1 min and take the reading from the scale to the nearest 0.1 cm. This reading will give directly in centimetres the height, H2, of the material.
