ASTM WK77169
New Practice for Measurement of fluorescent materials using hemispherical geometries
1. Scope
The scope of the Committee shall be to promote knowledge of color and appearance properties and characteristics, and to encourage the improvement and development of standards for describing and evaluating appearance properties by:
Stimulating and sponsoring research into color and appearance problems.
Formulating terms, nomenclature, and definitions generally applicable for describing color and appearance.
Developing, or coordinating with other technical committees to develop standards for measuring fundamental and general properties.
Developing standard specifications for those attributes of color and appearance which are appropriate.
Assisting other technical committees to improve color and appearance standards and specifications by advice, suggestions, and dissemination of information.
Reviewing and recommending approval or revision of ASTM standards, existing or proposed, involving color and appearance factors.
Serving, with the approval of the ASTM Board of Directors, as liaison agent between the Society and other organizations in matters concerned with factors of color and appearance.
Keywords
fluorescence; color; colorimetry; spectrophotometry; reflectance; transmittance; radiance factor; integrating sphere; luminescence; phosphorescence; instrumental measurement
Rationale
E991-11 recommends bidirectional, rather than integrating-sphere geometries for fluorescence measurement (see 5.7.1) but integrating spheres are used for measurement of fluorescent textiles and paper. A standard for the measurement of fluorescent materials using hemispherical geometries is needed. Guidance is needed for sphere-based methods.
The title and scope are in draft form and are under development within this ASTM Committee.
