Provides specifications for a range of graduated straight pipettes required for general laboratory use.

This Standard applies to a series of graduated straight pipettes suitable for general laboratory purposes. The following four types of pipette are specified:(a) Type I-N pipettes, which are adjusted for delivery of a liquid from the zero line at the top to any graduation line, where the nominal capacity is represented by the lowest graduation line.(b) Type II-N pipettes, which are adjusted for delivery of a liquid from any graduation line down to the jet, where the nominal capacity is represented by the highest graduation line.(c) Type III-N and Type III-W pipettes, which are adjusted for delivery of a liquid from the zero line at the top to any graduation line, where the nominal capacity is obtained by delivery down to the jet.Two classes of accuracy are specified, Class A pipettes being of higher accuracy than Class B pipettes. Type III-N pipettes are only Class B while Type III-W pipettes are only Class A.NOTE: The method of verification and notes for the use of pipettes are given in AS 2162.
