This International Standard specifies requirements for a series of pyknometers for general laboratory use for the
determination of the densities of liquids.
Specialized pyknometers for use with particular products, or otherwise not in common use, are excluded. Sufficient
details to define such pyknometers should be included in International Standards which specify or describe their
use.
A device suitable for adjustment of the liquid level in the neck of the Reischauer pyknometer is shown in annex A.
