ASTM E1273-88(2003)

Standard Specification for Color Coding of Reusable Laboratory Pipets

ABSTRACT
This specification covers a system of color coding of reusable laboratory pipets for identification of nominal capacities and units of sub-division. This specification applies to one-mark and graduated pipets of nominal capacities. The color code and marking requirements for one-mark and graduated pipets shall take the form of color bands in accordance to the color coding system indicated in this specification.
SCOPE
1.1 This specification covers a system of color coding for one-mark pipets for identification of nominal capacities, and for graduated pipets for identification of nominal capacities and units of sub-division.
1.2 This specification applies to one-mark and graduated pipets of the nominal capacities listed in Table 1 and Table 2, respectively.
Note 1—Many pipets not covered by other ASTM standards are included in and , in order, firstly, to ensure uniformity of color coding as far as possible for non-standard as well as standard pipets and, secondly, to reserve suitable codes for possible future standards for other types of pipet.
