Status: historical
Page Count: 3
ICS Code (Colours and measurement of light): 17.180.20
scope:

1.1 This test method describes 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 flat object-color specimen. It is especially recommended for measuring retroreflective specimens, fluorescent specimens, and specimens of intermediate gloss.

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 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
