New Guide for Use of Quality Related Terms in Measurement and Testing of Optical Properties of Materials

1. Scope

The scope of the Committee shall be to promote knowledge of color and appearance properties and characteristics, and to encourage the improvement and development of standards for describing and evaluating appearance properties by:

Stimulating and sponsoring research into color and appearance problems.

Formulating terms, nomenclature, and definitions generally applicable for describing color and appearance.

Developing, or coordinating with other technical committees to develop standards for measuring fundamental and general properties.

Developing standard specifications for those attributes of color and appearance which are appropriate.

Assisting other technical committees to improve color and appearance standards and specifications by advice, suggestions, and dissemination of information.

Reviewing and recommending approval or revision of ASTM standards, existing or proposed, involving color and appearance factors.

Serving, with the approval of the ASTM Board of Directors, as liaison agent between the Society and other organizations in matters concerned with factors of color and appearance.


accuracy; bias; precision; quality terms; repeatability; reproducibility; uncertainty


Users are colorists who must deal with the fact that collections of color-differences do not form a normal distribution. This means that conventional statistics definitions such as are contained in E456 may not apply to their situation. This guide takes them through the subject matter from their own perspective.

The title and scope are in draft form and are under development within this ASTM Committee.
