ASTM E1273-88(1997)e1
(Specification)Standard Specification for Color Coding of Reusable Laboratory Pipets
Standard Specification for Color Coding of Reusable Laboratory Pipets
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 Tables 1 and 2, respectively. Note 1-Many pipets not covered by other ASTM standards are included in Tables 1 and 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 standards for other types of pipet.

1.1 This specification covers a system of color coding for

one-mark pipets for identification of nominal capacities, and
0.002 2 red
for graduated pipets for identification of nominal capacities and

NOTE 1—Many pipets not covered by other ASTM standards are

3.1 The purpose of this specification is to ensure that if a 4 2 red
