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 color-difference tolerances.
This practice is general in scope rather than specific as to instrument or material.
