This specification covers requirements of precision (Class A) and general purpose (Class B) grade glass measuring pipets used for volume measurement of liquids. Pipets covered by this specification may be of the standard taper tip type (Style 1) or of the long taper tip type (Style 2), which is only available for Class B pipets, and are available in nine different capacities. The pipet shall be manufactured from annealed borosilicate glass into a straight, one-piece construction that is free of defects which may distort the appearance of the liquid surface. The pipets shall be marked wit permanent and legible graduation lines lying in a plane perpendicular to the vertical axis of the pipet by etching the glass and filling the etched area with a permanent pigment, by etching through a vertical colored stripe fused into the glass, by applying a stain fired into the glass without etching, or by applying an enamel fired into the glass without etching. In addition, the pipet shall also be color coded with one or two color bands. Pipets shall undergo testing such as specified for reusable laboratory glassware.


1.1 This specification covers requirements for glass measuring pipets of precision and general purpose grades, used in measuring volumes of liquids.
