scope:

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 E991 and Practice E2153.

1.4 Procedures required for the measurement of color using filter colorimeters are contained in Test Method E1347 and this standard does not address those instruments.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
