Paper and board. Determination of CIE whiteness, D65/10° (outdoor daylight) Ingestion-build-202139 swimming pool and recreational waters1 Scope This document specifies the procedure to be used for determining the whiteness of papers and boards. The values obtained correspond to the visual appearance of white papers and boards with or without fluorescent whitening agents when they are viewed under the CIE D65 daylight standard illuminant. It is based on reflectance data obtained over the full visible spectral range (VIS) in contrast to the measurement of ISO brightness which is limited
