IEC/TR 62732:2012(E) describes how to construct a three-digit code, representing a shorthand string combining the nominal general colour rendering index and the nominal correlated colour temperature. The contents of the corrigendum of December 2012 have been included in this copy.

Abstract

Overview

Key Topics

Three-Digit Code Structure: The code format is 'xyy', where 'x' stands for the general colour rendering index category and 'yy' corresponds to the correlated colour temperature.
- Colour Rendering Index Designation: The first digit indicates the CRI band:
  - "7" for CRI 70-79
  - "8" for CRI 80-89
  - "9" for CRI 90 and above
  - Codes below "7" are extrapolated as needed.
- Correlated Colour Temperature Designation: The following two digits represent the CCT value in hundreds of Kelvin (K), rounded to the nearest whole number.
Industry Application: The code is deeply integrated into lamp labeling, product datasheets, and technical specifications worldwide.
Harmonization: Aligns with references such as IEC 61231 for further consistency in lamp coding systems.

Applications

The IEC TR 62732 three-digit code serves essential roles across the lighting and electrical sectors, including:

Product Identification: Quickly conveys essential color properties on lamp packaging, datasheets, and specifications, enabling easier product comparison and selection.
Inventory and Procurement: Standardized codes streamline communication between manufacturers, distributors, and service providers, reducing errors in ordering and stocking.
Lighting Design and Specification: Lighting professionals rely on the three-digit code to ensure compatibility with project requirements for color quality and appearance.
Regulation and Compliance: Used by regulatory bodies and market surveillance for the enforcement of color rendering and temperature standards in lighting products.
End-User Reference: Helps customers choose lamps with the right color temperature and rendering qualities for residential, commercial, or industrial environments.

Example: A lamp labeled "830" has a nominal CRI between 80-89 and a correlated color temperature of approximately 3000K.

Related Standards

Utilizing IEC TR 62732:2012 often involves referencing or aligning with additional key international standards, such as:

IEC 61231: International lamp coding system (ILCOS) - provides a broader framework for lamp identification and coding.
ISO/IEC Directives: Ensure that coding practices conform to international documentation and standardization guidelines.
Other IEC Standards for Lamps and Luminaires: Many product standards cite the three-digit code system to harmonize color property communication across applications.

Practical Value

Adoption of the IEC TR 62732 three-digit code promotes clear, uniform communication of lamp color properties across global markets. It minimizes misunderstandings, supports swift decision-making, and enhances compliance with product labeling regulations. By following this standard, organizations ensure that key information about color rendering and temperature is reliably conveyed, contributing to better lighting solutions and satisfied end-users.
