ASTM E1349-06(2013) Standard Test Method for Reflectance Factor and Color by Spectrophotometry Using Bidirectional (45deg;:0deg; or 0deg;:45deg;) Geometry
1.1 This test method covers the instrumental measurement of the reflection properties and color of object-color specimens by use of a spectrophotometer or spectrocolorimeter with a bidirectional optical measuring system, such as annular, circumferential, or uniplanar 45:0 or 0:45 geometry.
1.2 This test method is generally suitable for any non-fluorescent, flat object-color specimen. It is especially recommended for measuring retroreflective specimens and specimens of intermediate gloss.
1.3 Procedures required for the measurement of fluorescent object color are given in Practice
