This International Standard provides methods for the testing, calibration and use of volumetric instruments
made from glass in order to obtain the best accuracy in use.
The International Standards for the individual volumetric instruments include clauses on the definition of
capacity; these clauses describe the method of manipulation in sufficient detail to define the capacity without
ambiguity. This International Standard contains supplementary information.
The procedures are applicable to volumetric instruments with nominal capacities in the range of 0,1 ml to
10 000 ml. These include: single-volume pipettes (see ISO 648) without subdivisions; graduated measuring
pipettes and dilution pipettes, with partial or complete subdivisions (see ISO 835); burettes (see ISO 385);
volumetric flasks (see ISO 1042); and graduated measuring cylinders (see ISO 4788). The procedures are not
recommended for testing of volumetric instruments with capacities below 0,1 ml such as micro-glassware.
This International Standard does not deal specifically with pyknometers as specified in ISO 3507. However,
the procedures specified below for the determination of volume of glassware can, for the most part, also be
followed for the calibration of pyknometers.
