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

Importancia y uso:

4.1 The options available in methods for the measurement of color or color-difference are many. These involve choices in: (1) specimens, (2) geometric and spectral properties of instruments, (3) calibration bases for standards used, (4) procedure for sample handling including conditioning, (5) procedure for taking data, and (6) equations for converting instrumental data to final results. Once the measurements have been made, it is essential to document what has been done for the purpose of interlaboratory comparisons, or for future use. A sample form is provided in Fig. 1 to record identifying information applicable to any instrumental method of color or color-difference measurement.

4.2 Refer to Guide E179, Practices E991, E1164, E1345, E1708, E1767, E2152, and E2194 and Test Methods D5386, D6166, E1247, E1331, E1347, E1348, and E1349, for specific details of measurements.
