Continues the series by including all revisions to existing standards made since the publications of the fifth edition (no date noted) and a number of new standards. They provide guidance in the instrumentation and visual appraisal of the appearance of materials, and to describe specific measurement instruments and techniques for their use. The appearances appraised involved standard illuminants and observers as well as actual light sources and human observers. Most of the standards relate to a variety of materials, which include those that reflect and transmit light and those that are self-luminous. The introduction, with accompanying tables, provides a basic overview of the science of appearance, distinguishing between the various optical properties of materials and the appropriate standard test methods. It also discusses some industry-specific color standards in the US. The disk presumably contains the same material as the volume. Annotation c. Book News, Inc., Portland, OR (booknews.com) Read Less
