Spectrophotometer Color Test

Purpose of Test:

A spectrophotometer is used to measure the differences in color between a reference and a test specimen and are determined from measurements made by use of a spectral based or filter based colorimeter.

Color-difference magnitudes are computed, from differences in these color-scale values, that represent the perceived color differences between the reference and the test specimen.

Measuring geometry is d/10, Light source D65.

Device/Machine: UV-VIS Spectrophotometer.

Calibration Frequency:

o UV-VIS Spectrophotometer: Every 8 Hours

Approximate  Test Duration:

o  Sample preparation and Test time: 30 minutes

Specification: ASTM D2244
