(Specification)Standard Specification for Color Coding of Reusable Laboratory Pipets
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
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.
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.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
