Standard Practice for Reducing the Effect of Variability of Color Measurement by Use of Multiple Measurements
|Publication Date:||10 June 1998|
|ICS Code (Colours and measurement of light):||17.180.20|
Reduction of the variability associated with average color or color-difference measurements of object-color specimens is achieved by statistical analysis of the results of multiple measurements on a single specimen, or by measurement of multiple specimens, whichever is appropriate.
This practice provides a means for the determination of the number of measurements required to reduce the variability to a predetermined fraction of the relevant color or colordifference tolerances.
This practice is general in scope rather than specific as to instrument or material.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
