The measurement of diffuse reflectance factor is a procedure which forms the basis of a number of optical test methods[2]. This Standard specifies the equipment and describes the general procedure for measuring diffuse reflectance factor as required for the evaluation of the physical correlates of specific appearance properties of pulp, paper and paperboard. Diffuse reflectance factor (R) is the ratio, expressed as a percentage, of the radiant (luminous) flux reflected by a body within a specified cone, to that reflected by the perfect reflecting diffuser under the same conditions of viewing and diffuse illumination.

Originated in Australia as AS 1301.436s-1991.
