(Practice)Standard Practice for Obtaining Spectrometric Data for Object-Color Evaluation
Standard Practice for Obtaining Spectrometric Data for Object-Color Evaluation
SCOPE
1.1 This practice covers the instrumental measurement requirements, calibration procedures, and material standards needed to obtain precise spectral data for computing the colors of objects.
1.2 This practice lists the parameters that must be specified when spectrometric measurements are required in specific methods, practices, or specifications.
1.3 Most sections of this practice apply to both spectrometers, which can produce spectral data as output, and spectrocolorimeters, which are similar in principle but can produce only colorimetric data as output. Exceptions to this applicability are noted.
1.4 This practice is limited in scope to spectrometers and spectrometric colorimeters that employ only a single monochromator. This practice is general as to the materials to be characterized for color.
1.5 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
The fundamental procedure for evaluating the color of a reflecting or transmitting object is to obtain
spectrometric data for specified illuminating and viewing conditions, and from these data to compute
tristimulus values based on a CIE (International Commission on Illumination) standard observer and
a CIE standard illuminant. The considerations involved and the procedures used to obtain precise
spectrometric data are contained in this practice. The values and procedures for computing CIE
tristimulus values from spectrometric data are contained in Practice E 308. Considerations regarding
the selection of appropriate illuminating and viewing geometries are contained in Guide E 179.
