ASTM E1345-98(2003)

Standard Practice for Reducing the Effect of Variability of Color Measurement by Use of Multiple Measurements
standard by ASTM International, 12/01/2003

Category: ASTM

Description

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.
