Full title and description

ISO 1769:1975 — Laboratory glassware — Pipettes — Colour coding. This International Standard specifies a system of colour coding for one‑mark (fixed‑volume) pipettes and for graduated pipettes to identify nominal capacities and units of subdivision; it also defines the colour‑band locations and the method of marking. The official ISO record indicates the published 1975 edition (English and French) and notes the edition remains confirmed/current following periodic review.

Abstract

A concise colour‑coding system is defined for laboratory pipettes: one‑mark pipettes are identified by colour for nominal capacity; graduated pipettes are identified by colour for nominal capacity and for the unit of subdivision. The standard tables the colour bands for different capacities and specifies the marking method; requirements and test methods for colour durability were to be considered at a later date.

Scope

This standard applies to glass laboratory pipettes and establishes a standardised colour‑band identification scheme so that nominal capacities (for single‑mark pipettes) and nominal capacities plus unit‑of‑subdivision (for graduated pipettes) can be instantly recognised by inspection. The scope covers the positions and colours of bands and the method of marking; it does not set out in this edition detailed test methods for long‑term durability of the applied colours (those were to be considered in subsequent work).

Key topics and requirements

• Defined colour‑coding scheme for one‑mark (fixed‑volume) pipettes to identify nominal capacity.
• Defined colour‑coding scheme for graduated pipettes to identify nominal capacity and unit of subdivision.
• Tabulated colour bands mapped to specific capacities (band colours and their positions on the pipette).
• Specification of the marking method (how and where colour bands are applied to pipettes).
• Note that durability/performance requirements and test methods for the colours were deferred for later consideration in subsequent work programs.

These are the principal technical prescriptions in the standard as published.

Typical use and users

Laboratory managers and technicians use the colour coding to quickly identify pipette volumes during routine work; manufacturers of laboratory glassware and pipettes apply the specified colour bands on products to ensure interoperability and user safety; procurement/specification authors and calibration/test laboratories refer to the standard when specifying or verifying pipette labelling and marking. Medical, analytical, research and teaching laboratories are typical end users. Industry product information for pipette packaging and suppliers commonly cites conformity to ISO 1769 for colour coding.

Related standards

ISO 1769 sits within the ISO/TC 48 family of standards on laboratory glassware and volumetric instruments. Other related documents include national adoptions/adaptations (for example GOST R ISO 1769 versions published for Russia in the 1990s) and complementary ISO standards covering pipette performance and volumetric glassware (manufacturers often reference ISO volumetric/pipette performance standards alongside ISO 1769 for marking).

FAQ

Q: What is this standard?

A: ISO 1769:1975 is an International Standard that defines a colour‑band coding system for identifying nominal capacities (and subdivision unit for graduated pipettes) on laboratory pipettes.

Q: What does it cover?

A: It covers the prescribed colours, the location of colour bands and the method of marking for one‑mark (fixed‑volume) and graduated pipettes; it tables the colour assignments for different capacities. The 1975 text does not include detailed durability test methods for the colours, which were to be addressed later.

Q: Who typically uses it?

A: Manufacturers of pipettes and laboratory glassware, procurement/specification writers, laboratory managers and technicians, and calibration/test laboratories use the standard to ensure consistent visual identification of pipette volumes.

Q: Is it current or superseded?

A: The original ISO 1769:1975 edition is recorded in the ISO catalogue and has been subject to periodic review; ISO records show the 1975 edition was confirmed in review cycles (confirmed as current in recent reviews). Users should check the ISO catalogue or national standards bodies for any later revisions or national adoptions before relying on it as the sole normative reference.

Q: Is it part of a series?

A: It belongs functionally to the family of ISO standards for laboratory glassware and volumetric instruments developed under ISO/TC 48 (Laboratory equipment). It is commonly used alongside other ISO standards that address pipette performance and volumetric measurement.

Q: What are the key keywords?

A: pipette, colour coding, colour code, laboratory glassware, nominal capacity, graduated pipette, marking, ISO 1769.
