Provides technical guidance to the necessary requirements of accuracy, inertness and robustness of laboratory-type measuring cylinders and claims to provide assurance of a minimum quality product that can stand up to routine laboratory use. The detailed methods of test allow flexibility in the choice of test apparatus without sacrificing essential specifications of the key components of such apparatus and, therefore, the criteria that the test cylinder must meet.

This standard specifies requirements for a series of plastics measuring cylinders of capacities ranging from 10 mL to 4000 mL, each having a graduated volumetric scale and a pouring lip and of the typical design shown in Fig. 1.
