ASTM E1273-88(2008)

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.
SIGNIFICANCE AND USE
The purpose of this specification is to ensure that if a color code is used on pipets, all manufacturers will use the same code; it is not intended as an encouragement of color coding if this is not required.
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 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 standards for other types of pipet.

3. Significance and Use
3.1 The purpose of this specification is to ensure that if a color code is used on pipets, all manufacturers will use the same code;
it is not intended as an encouragement of color coding if this is not required.
4. Color Properties
4.1 Coding—The color coding used on one-mark pipets shall be in accordance with Table 1, and graduated pipets shall be in
accordance with Table 2.
4.2 Variations—Variations in the enamels used in the methods of application appropriate for pipets made from different types
of glass inevitably result in minor variations of color, and it is therefore not appropriate to specify closely the seven colors listed
in the tables.
5. Marking Requirements
5.1 The color code shall take the form of color bands extending at least 150° around the circumference of the pipet and situated
not more than 70 mm from the top of the pipet and not less than 20 mm above the nearest graduation line.

color, each band shall be 3 to 5 mm wide and the two bands shall be separated by a space of 2 to 3 mm. Color bands do not have
to be continuous but may be broken as long as they cover 40 % of the circumference of the pipet.
NOTE 2—Pipets calibrated to deliver by blowing out the last drop shall be identified by a wide band or two narrow bands permanently marked on their
top end.
