ASTM E805-01a

Standard Practice for Identification of Instrumental Methods of Color or Color-Difference Measurement of Materials

SCOPE
1.1 This practice covers the documentation of instrumental measurement of color or color difference for current communication or for future reference. The practice is applicable to instrumental measurements of materials where color is seen by reflected, transmitted or emitted light and any combinations of one or more of these processes. The practice is recommended for documentation of methodology in interlaboratory color-measurement programs.
1.2 An adequate identification of an instrumental measure of color or color-difference consists of five parts:
1.2.1 Nature and source of available samples and the form of specimens actually measured,
1.2.2 Instrumental conditions of measurement, including instrument geometrical and spectral conditions of measurement,
1.2.3 Standards used,
1.2.4 Data acquisition procedure, and
1.2.5 Color scales employed.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
