ASTM E1273 : 88(2008)

Standard Specification for Color Coding of Reusable Laboratory Pipets

Standard Details

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 StandardDetails are included in Table 1 and Table 2, 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 StandardDetails for other types of pipet.
