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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

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.

1. 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.
