This document provides methods for the testing, calibration and use of volumetric instruments made from glass and plastic in order to obtain the best accuracy in use.<\/p>\n

NOTE\u00a0\u00a0\u00a0\u00a0\u00a0 Testing is the process by which the conformity of the individual volumetric instrument with the appropriate standard is determined, resulting in the determination of its error of measurement at one or more points.<\/p>\n

This document is applicable to volumetric instruments with nominal capacities in the range of 100\u00a0\u00b5l to 10\u00a0000\u00a0ml. These include single-volume pipettes (see ISO\u00a0648), graduated pipettes (see ISO\u00a0835), burettes (see ISO\u00a0385), volumetric flasks (see ISO\u00a01042 and ISO\u00a05215), and graduated measuring cylinders (see ISO\u00a04788 and ISO\u00a06706).<\/p>\n

The methods are not intended for testing of volumetric instruments with capacities below 100\u00a0\u00b5l such as micro-glassware.<\/p>\n

This document does not deal specifically with pycnometers as specified in ISO\u00a03507. However, the procedures specified for the determination of volume of glassware can, for the most part, also be followed for the determination of a pycnometer volume. For some types of pycnometers, special handling can be necessary.<\/p>\n","protected":false},"excerpt":{"rendered":"
