3 IJEFINITIONS

For the purpose of this Standard, the definitions below apply.

3.1 Capacity

The volume of water at 20°C, expressed in millilitres, contained by the flask at 20°C when tilled to the graduation line.

3.2 Neck

That part of the flask which is of apparently uniform internal diameter.

3.3 Reference temperature

The Standard temperature of 20°C at which the volumetric flask is intended to contain its nominal volume (nominal capacity).

3.4 Unit of volume

The term millilitre (rnL) is in accordance with the International System of Units (SI).

4 CLASSES OF ACCURACY

Two classes of accuracy are specified—

(a) Class A for (he higher grade: and

(b) Class B for the lower grade.

5 SERIES OF CAPACITIES

The series of capacities of one-mark volumetric flasks are as follows:

1, 2, 5, 10. 20. 25, 50. 100. 200. 250. 500. 1000. 2000 and 5000 mL

All these flasks may he finishcd with a plain neck or he provided with a stopper.

NOTE: If volumetric flasks of capacities other than those listed above are required. it is recommended that they conform, as far as possible, to the essential requirements of this Standard.
