The actual volume of the contents of a prepackage is the volume of liquid it in fact contains. In all checking operations the value employed for actual volume of the contents shall be measured at or corrected to a temperature of 20 °C.
Measuring container bottles shall be characterized by the following capacities which are always specified for a temperature of 20C: ...
1.3. the actual capacity of a bottle is the volume of liquid it in fact contains when it is filled exactly under the conditions corresponding theoretically to the nominal capacity. ...
In practice, the actual capacity of a measuring container bottle shall be checked by determining the quantity of water at 20°C which the bottle actually contains when filled to the level theoretically corresponding to the nominal capacity. It may also be checked indirectly by a method of equivalent accuracy.
Prepackages covered by this Directive shall be made up in such a way that the completed prepackages satisfy the following requirements:
1.1. the actual volume of the contents shall not be less, on average, than the nominal volume of the contents ...
