E1345-98(2008) Standard Practice for Reducing the Effect of Variability of Color Measurement by Use of Multiple Measurements
Published By | Publication Date | Number of Pages |
ASTM | 2008 | 5 |
1.1 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.
1.2 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.
1.3 This practice is general in scope rather than specific as to instrument or material.
