MT 186 BULK DENSITY
A known weight of a solid material is placed in a glass measuring cylinder and its volume measured (to determine the 'pour density'). The cylinder is then raised and allowed to fall vertically through a distance of 25 mm on to a rubber pad (50 times) or this is carried out using a Dry Substance Jolting Volumeter ISO 787 (Note 1). The volume is measured again (to determine the 'tap density').
