Determination of Density of
liquids in respect of National Standards
1. Determine the weight of a clean cup in grams. As an alternative, the cup may be
supplied with an accurate tare weight for use with two-pan laboratory balances.
2. Remove cover and fill within 2mm of brim with the material to be tested.
3. Carefully replace cover so that air and excess material is expelled through vent.
4. Wipe over cover to remove surplus and reweigh. By subtracting the original weight
of the cup the weight of the contents will be found. If a tare weight was used at the
start the balance will show the weight of the contents.
5. Clean thoroughly immediately after use.
