Historical Standard: ASTM E1345-98 Standard Practice for Reducing the Effect of Variability of Color Measurement by Use of Multiple Measurements
SUPERSEDED (see Active link, below)
ASTM E1345
1. Scope
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 variablilty 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.
